IBPS AFO cheat sheet

Soil pH ranges: strongly acidic <5.5, moderately acidic 5.5-6.5, near neutral 6.6-7.3, alkaline >7.3; most field crops peak between pH 6.0 and 7.5, while tea prefers pH 4.5-5.5 and rice tolerates 5.5-6.5.

N-P-K is expressed as N, P2O5, and K2O: elemental P = P2O5 × 0.44 and elemental K = K2O × 0.83; a 50 kg bag of 10:26:26 supplies 5 kg N, 13 kg P2O5, and 13 kg K2O.

The three primary plant macronutrients are N, P, and K; secondary nutrients are Ca, Mg, and S; the recognized micronutrients are Fe, Mn, Zn, Cu, B, Mo, Cl, and Ni.

Nitrogen is taken up chiefly as nitrate (NO3-) and ammonium (NH4+); it is mobile in the plant, so deficiency appears first as yellowing of older, lower leaves.

Phosphorus deficiency shows as stunted growth with purplish or dark green older leaves; potassium deficiency shows as marginal scorching of older leaves.

Zinc deficiency in rice appears as khaira (brown rusty spots on middle leaves); boron deficiency causes hollow heart in cauliflower and browning in rice.

Legumes fix atmospheric nitrogen through Rhizobium in root nodules; inoculation is recommended when a field has no recent history of the specific legume crop.

Integrated Pest Management follows the sequence: monitor and survey, then cultural and mechanical methods, then biological control, then need-based chemical sprays; the economic threshold level (ETL) is the pest density at which control becomes economically justified.

Drip irrigation saves roughly 40-60% water compared with surface flooding; sprinkler irrigation suits close-growing crops, while drip suits wide-row crops, orchards, and vegetables.

Subject-verb agreement: a singular subject takes a singular verb, but 'one of + plural noun' takes a singular verb, as in 'One of the officers is absent'; collective nouns take a singular verb when acting as a unit.

Common error patterns: 'discuss about' and 'comprise of' are redundant; 'comprise' takes no preposition, while 'comprise of' should be replaced by 'consist of'.

Prepositions: 'cope with', 'comply with', 'conducive to', 'deprived of', 'composed of', 'adapted to', 'averse to', 'capable of', 'eligible for', 'superior to'.

For a reading-comprehension passage, locate the answer sentence rather than relying on outside knowledge; the correct option restates the passage, while distractor options add unsupported claims or reverse the cause-effect relation.

Cloze tests: read the whole passage first, then choose the option that fits both meaning and grammar; check collocation, tense, and article agreement.

Para jumbles: identify the opening sentence (usually general, introducing a subject without pronouns referring back), then chain sentences by pronouns, conjunctions, and repeated keywords.

Synonyms and antonyms should be judged from an example context, because a word such as 'address' can mean to speak, to deal with, or a location.

Idioms often appear in error spotting: 'at the drop of a hat' means instantly, 'a bolt from the blue' means a sudden shock, and 'to bell the cat' means to take the risk first.

For sentence improvement, prefer the shortest grammatically correct option; an option that changes the meaning of the original sentence is generally incorrect.

Percentage change: percentage increase = (new - old) / old × 100; a successive increase of a% then b% is equivalent to a + b + ab/100.

Simple interest SI = P × R × T / 100; compound interest CI = P × (1 + R/100)^T - P, compounded annually; for half-yearly compounding, halve the rate and double the time.

Profit and loss: profit% is calculated on cost price by default; selling price = CP × (100 + profit%) / 100; for successive discounts of a% and b%, net discount = a + b - ab/100.

Time, speed and distance: distance = speed × time; average speed for equal distances at speeds x and y is 2xy / (x + y), not (x + y)/2.

Boats and streams: downstream speed = boat speed + stream speed; upstream speed = boat speed - stream speed; boat speed = (downstream + upstream)/2.

Time and work: if A finishes in x days and B in y days, together they take xy/(x + y) days; use the LCM method to express rates as units per day.

Ratio and mixture: alligation rule gives the ratio of two components as (higher - mean) : (mean - lower); repeated replacement leaves final quantity = original × (1 - replaced/total)^n.

Mensuration: area of circle = πr², circumference = 2πr; cylinder volume = πr²h; sphere volume = (4/3)πr³; cone volume = (1/3)πr²h.

Data interpretation: compute the required ratio or percentage directly from the table or graph; convert percentages to fractions (12.5% = 1/8, 16.67% = 1/6, 33.33% = 1/3) to speed up calculation.

In a linear arrangement facing north, a person to the right of another has a higher position number; when facing south, the mapping reverses, so right becomes the lower position number.

For circular seating facing the centre, a person's immediate left is the next position clockwise; when facing outward, immediate left is anticlockwise.

Blood relations: draw a family tree using symbols (+ male, - female, = married, | child) and never assume gender from a name alone; 'brother of my father' is uncle, and 'son of my sister' is nephew.

Syllogism: a conclusion follows only if it is true in every possible Venn diagram of the given statements; 'some A are B' does not imply 'some B are not A'.

Coding-decoding: check letter positions (A=1 to Z=26) for shifts, reversals, or sums; a common pattern is each letter moved by an increasing step.

Inequalities: chain the symbols, then test the conclusion; 'A > B ≥ C' gives A > C but not C > A, and only 'either-or' applies when the pair is complementary and both individually false.

Direction sense: track net displacement with north as +y and east as +x; the shortest distance uses the Pythagorean theorem, and a left turn while facing north points west.

Series completion: check differences of differences, alternate-term patterns, and prime or square multipliers; number series often combine two interleaved sequences.

Puzzles with multiple attributes: start with the most restrictive clue, and use a grid to eliminate options rather than holding all possibilities in memory.

The Reserve Bank of India was established on 1 April 1935 under the RBI Act, 1934, and was nationalised in 1949; it is the monetary authority and regulates banks.

NABARD, established in 1982, is the apex institution for agricultural and rural credit; it refinances cooperatives, RRBs, and rural infrastructure through the Rural Infrastructure Development Fund.

Priority sector lending targets: 40% of adjusted net bank credit for domestic commercial banks, including 18% for agriculture and 7.5% for micro enterprises; RRBs and small finance banks carry a 75% target.

The Kisan Credit Card scheme gives short-term crop loans and was extended to dairy, fishery, and animal husbandry; interest subvention applies to prompt repayment of short-term crop loans.

Pradhan Mantri Fasal Bima Yojana: farmers pay 2% premium for kharif food and oilseed crops, 1.5% for rabi crops, and 5% for commercial and horticultural crops, with the balance subsidised by the government.

Pradhan Mantri Kisan Samman Nidhi provides Rs 6,000 per year in three instalments of Rs 2,000 to eligible landholding farmer families.

Deposit insurance under DICGC covers up to Rs 5 lakh per depositor per bank for both principal and interest.

The Monetary Policy Committee has six members and sets the repo rate; raising the repo rate tightens liquidity, while the reverse repo absorbs liquidity.

Nationalised banks: 14 banks were nationalised in 1969 and 6 more in 1980; regional rural banks were set up in 1975 on the recommendation of the Narasimham Working Group.

Legumes fix atmospheric nitrogen through Rhizobium in root nodules; inoculation is recommended when a field has no recent history of the specific legume crop.

Integrated Pest Management follows the sequence: monitor and survey, then cultural and mechanical methods, then biological control, then need-based chemical sprays; the economic threshold level (ETL) is the pest density at which control becomes economically justified.

Drip irrigation saves roughly 40-60% water compared with surface flooding; sprinkler irrigation suits close-growing crops, while drip suits wide-row crops, orchards, and vegetables.

Subject-verb agreement: a singular subject takes a singular verb, but 'one of + plural noun' takes a singular verb, as in 'One of the officers is absent'; collective nouns take a singular verb when acting as a unit.

Common error patterns: 'discuss about' and 'comprise of' are redundant; 'comprise' takes no preposition, while 'comprise of' should be replaced by 'consist of'.

Prepositions: 'cope with', 'comply with', 'conducive to', 'deprived of', 'composed of', 'adapted to', 'averse to', 'capable of', 'eligible for', 'superior to'.

For a reading-comprehension passage, locate the answer sentence rather than relying on outside knowledge; the correct option restates the passage, while distractor options add unsupported claims or reverse the cause-effect relation.

Cloze tests: read the whole passage first, then choose the option that fits both meaning and grammar; check collocation, tense, and article agreement.

Para jumbles: identify the opening sentence (usually general, introducing a subject without pronouns referring back), then chain sentences by pronouns, conjunctions, and repeated keywords.

Synonyms and antonyms should be judged from an example context, because a word such as 'address' can mean to speak, to deal with, or a location.

Idioms often appear in error spotting: 'at the drop of a hat' means instantly, 'a bolt from the blue' means a sudden shock, and 'to bell the cat' means to take the risk first.

For sentence improvement, prefer the shortest grammatically correct option; an option that changes the meaning of the original sentence is generally incorrect.

Percentage change: percentage increase = (new - old) / old × 100; a successive increase of a% then b% is equivalent to a + b + ab/100.

Simple interest SI = P × R × T / 100; compound interest CI = P × (1 + R/100)^T - P, compounded annually; for half-yearly compounding, halve the rate and double the time.

Profit and loss: profit% is calculated on cost price by default; selling price = CP × (100 + profit%) / 100; for successive discounts of a% and b%, net discount = a + b - ab/100.

Time, speed and distance: distance = speed × time; average speed for equal distances at speeds x and y is 2xy / (x + y), not (x + y)/2.

Boats and streams: downstream speed = boat speed + stream speed; upstream speed = boat speed - stream speed; boat speed = (downstream + upstream)/2.

Time and work: if A finishes in x days and B in y days, together they take xy/(x + y) days; use the LCM method to express rates as units per day.

Ratio and mixture: alligation rule gives the ratio of two components as (higher - mean) : (mean - lower); repeated replacement leaves final quantity = original × (1 - replaced/total)^n.

Mensuration: area of circle = πr², circumference = 2πr; cylinder volume = πr²h; sphere volume = (4/3)πr³; cone volume = (1/3)πr²h.

Data interpretation: compute the required ratio or percentage directly from the table or graph; convert percentages to fractions (12.5% = 1/8, 16.67% = 1/6, 33.33% = 1/3) to speed up calculation.

In a linear arrangement facing north, a person to the right of another has a higher position number; when facing south, the mapping reverses, so right becomes the lower position number.

For circular seating facing the centre, a person's immediate left is the next position clockwise; when facing outward, immediate left is anticlockwise.

Blood relations: draw a family tree using symbols (+ male, - female, = married, | child) and never assume gender from a name alone; 'brother of my father' is uncle, and 'son of my sister' is nephew.

Syllogism: a conclusion follows only if it is true in every possible Venn diagram of the given statements; 'some A are B' does not imply 'some B are not A'.

Coding-decoding: check letter positions (A=1 to Z=26) for shifts, reversals, or sums; a common pattern is each letter moved by an increasing step.

Inequalities: chain the symbols, then test the conclusion; 'A > B ≥ C' gives A > C but not C > A, and only 'either-or' applies when the pair is complementary and both individually false.

Direction sense: track net displacement with north as +y and east as +x; the shortest distance uses the Pythagorean theorem, and a left turn while facing north points west.

Series completion: check differences of differences, alternate-term patterns, and prime or square multipliers; number series often combine two interleaved sequences.

Puzzles with multiple attributes: start with the most restrictive clue, and use a grid to eliminate options rather than holding all possibilities in memory.

The Reserve Bank of India was established on 1 April 1935 under the RBI Act, 1934, and was nationalised in 1949; it is the monetary authority and regulates banks.

NABARD, established in 1982, is the apex institution for agricultural and rural credit; it refinances cooperatives, RRBs, and rural infrastructure through the Rural Infrastructure Development Fund.

Priority sector lending targets: 40% of adjusted net bank credit for domestic commercial banks, including 18% for agriculture and 7.5% for micro enterprises; RRBs and small finance banks carry a 75% target.

The Kisan Credit Card scheme gives short-term crop loans and was extended to dairy, fishery, and animal husbandry; interest subvention applies to prompt repayment of short-term crop loans.

Pradhan Mantri Fasal Bima Yojana: farmers pay 2% premium for kharif food and oilseed crops, 1.5% for rabi crops, and 5% for commercial and horticultural crops, with the balance subsidised by the government.

Pradhan Mantri Kisan Samman Nidhi provides Rs 6,000 per year in three instalments of Rs 2,000 to eligible landholding farmer families.

Deposit insurance under DICGC covers up to Rs 5 lakh per depositor per bank for both principal and interest.

The Monetary Policy Committee has six members and sets the repo rate; raising the repo rate tightens liquidity, while the reverse repo absorbs liquidity.

Nationalised banks: 14 banks were nationalised in 1969 and 6 more in 1980; regional rural banks were set up in 1975 on the recommendation of the Narasimham Working Group.

Soil pH ranges: strongly acidic <5.5, moderately acidic 5.5-6.5, near neutral 6.6-7.3, alkaline >7.3; most field crops peak between pH 6.0 and 7.5, while tea prefers pH 4.5-5.5 and rice tolerates 5.5-6.5.

N-P-K is expressed as N, P2O5, and K2O: elemental P = P2O5 × 0.44 and elemental K = K2O × 0.83; a 50 kg bag of 10:26:26 supplies 5 kg N, 13 kg P2O5, and 13 kg K2O.

The three primary plant macronutrients are N, P, and K; secondary nutrients are Ca, Mg, and S; the recognized micronutrients are Fe, Mn, Zn, Cu, B, Mo, Cl, and Ni.

Nitrogen is taken up chiefly as nitrate (NO3-) and ammonium (NH4+); it is mobile in the plant, so deficiency appears first as yellowing of older, lower leaves.

Phosphorus deficiency shows as stunted growth with purplish or dark green older leaves; potassium deficiency shows as marginal scorching of older leaves.

For a reading-comprehension passage, locate the answer sentence rather than relying on outside knowledge; the correct option restates the passage, while distractor options add unsupported claims or reverse the cause-effect relation.

Cloze tests: read the whole passage first, then choose the option that fits both meaning and grammar; check collocation, tense, and article agreement.

Para jumbles: identify the opening sentence (usually general, introducing a subject without pronouns referring back), then chain sentences by pronouns, conjunctions, and repeated keywords.

Synonyms and antonyms should be judged from an example context, because a word such as 'address' can mean to speak, to deal with, or a location.

Idioms often appear in error spotting: 'at the drop of a hat' means instantly, 'a bolt from the blue' means a sudden shock, and 'to bell the cat' means to take the risk first.

For sentence improvement, prefer the shortest grammatically correct option; an option that changes the meaning of the original sentence is generally incorrect.

Percentage change: percentage increase = (new - old) / old × 100; a successive increase of a% then b% is equivalent to a + b + ab/100.

Simple interest SI = P × R × T / 100; compound interest CI = P × (1 + R/100)^T - P, compounded annually; for half-yearly compounding, halve the rate and double the time.

Profit and loss: profit% is calculated on cost price by default; selling price = CP × (100 + profit%) / 100; for successive discounts of a% and b%, net discount = a + b - ab/100.

Time, speed and distance: distance = speed × time; average speed for equal distances at speeds x and y is 2xy / (x + y), not (x + y)/2.

Boats and streams: downstream speed = boat speed + stream speed; upstream speed = boat speed - stream speed; boat speed = (downstream + upstream)/2.

Time and work: if A finishes in x days and B in y days, together they take xy/(x + y) days; use the LCM method to express rates as units per day.

Ratio and mixture: alligation rule gives the ratio of two components as (higher - mean) : (mean - lower); repeated replacement leaves final quantity = original × (1 - replaced/total)^n.

Mensuration: area of circle = πr², circumference = 2πr; cylinder volume = πr²h; sphere volume = (4/3)πr³; cone volume = (1/3)πr²h.

Data interpretation: compute the required ratio or percentage directly from the table or graph; convert percentages to fractions (12.5% = 1/8, 16.67% = 1/6, 33.33% = 1/3) to speed up calculation.

In a linear arrangement facing north, a person to the right of another has a higher position number; when facing south, the mapping reverses, so right becomes the lower position number.

For circular seating facing the centre, a person's immediate left is the next position clockwise; when facing outward, immediate left is anticlockwise.

Blood relations: draw a family tree using symbols (+ male, - female, = married, | child) and never assume gender from a name alone; 'brother of my father' is uncle, and 'son of my sister' is nephew.

Syllogism: a conclusion follows only if it is true in every possible Venn diagram of the given statements; 'some A are B' does not imply 'some B are not A'.

Coding-decoding: check letter positions (A=1 to Z=26) for shifts, reversals, or sums; a common pattern is each letter moved by an increasing step.

Inequalities: chain the symbols, then test the conclusion; 'A > B ≥ C' gives A > C but not C > A, and only 'either-or' applies when the pair is complementary and both individually false.

Direction sense: track net displacement with north as +y and east as +x; the shortest distance uses the Pythagorean theorem, and a left turn while facing north points west.

Series completion: check differences of differences, alternate-term patterns, and prime or square multipliers; number series often combine two interleaved sequences.

Puzzles with multiple attributes: start with the most restrictive clue, and use a grid to eliminate options rather than holding all possibilities in memory.

The Reserve Bank of India was established on 1 April 1935 under the RBI Act, 1934, and was nationalised in 1949; it is the monetary authority and regulates banks.

NABARD, established in 1982, is the apex institution for agricultural and rural credit; it refinances cooperatives, RRBs, and rural infrastructure through the Rural Infrastructure Development Fund.

Priority sector lending targets: 40% of adjusted net bank credit for domestic commercial banks, including 18% for agriculture and 7.5% for micro enterprises; RRBs and small finance banks carry a 75% target.

The Kisan Credit Card scheme gives short-term crop loans and was extended to dairy, fishery, and animal husbandry; interest subvention applies to prompt repayment of short-term crop loans.

Pradhan Mantri Fasal Bima Yojana: farmers pay 2% premium for kharif food and oilseed crops, 1.5% for rabi crops, and 5% for commercial and horticultural crops, with the balance subsidised by the government.

Pradhan Mantri Kisan Samman Nidhi provides Rs 6,000 per year in three instalments of Rs 2,000 to eligible landholding farmer families.

Deposit insurance under DICGC covers up to Rs 5 lakh per depositor per bank for both principal and interest.

The Monetary Policy Committee has six members and sets the repo rate; raising the repo rate tightens liquidity, while the reverse repo absorbs liquidity.

Nationalised banks: 14 banks were nationalised in 1969 and 6 more in 1980; regional rural banks were set up in 1975 on the recommendation of the Narasimham Working Group.

Soil pH ranges: strongly acidic <5.5, moderately acidic 5.5-6.5, near neutral 6.6-7.3, alkaline >7.3; most field crops peak between pH 6.0 and 7.5, while tea prefers pH 4.5-5.5 and rice tolerates 5.5-6.5.

N-P-K is expressed as N, P2O5, and K2O: elemental P = P2O5 × 0.44 and elemental K = K2O × 0.83; a 50 kg bag of 10:26:26 supplies 5 kg N, 13 kg P2O5, and 13 kg K2O.

The three primary plant macronutrients are N, P, and K; secondary nutrients are Ca, Mg, and S; the recognized micronutrients are Fe, Mn, Zn, Cu, B, Mo, Cl, and Ni.

Nitrogen is taken up chiefly as nitrate (NO3-) and ammonium (NH4+); it is mobile in the plant, so deficiency appears first as yellowing of older, lower leaves.

Phosphorus deficiency shows as stunted growth with purplish or dark green older leaves; potassium deficiency shows as marginal scorching of older leaves.

Zinc deficiency in rice appears as khaira (brown rusty spots on middle leaves); boron deficiency causes hollow heart in cauliflower and browning in rice.

Legumes fix atmospheric nitrogen through Rhizobium in root nodules; inoculation is recommended when a field has no recent history of the specific legume crop.

Integrated Pest Management follows the sequence: monitor and survey, then cultural and mechanical methods, then biological control, then need-based chemical sprays; the economic threshold level (ETL) is the pest density at which control becomes economically justified.

Drip irrigation saves roughly 40-60% water compared with surface flooding; sprinkler irrigation suits close-growing crops, while drip suits wide-row crops, orchards, and vegetables.

Subject-verb agreement: a singular subject takes a singular verb, but 'one of + plural noun' takes a singular verb, as in 'One of the officers is absent'; collective nouns take a singular verb when acting as a unit.

Common error patterns: 'discuss about' and 'comprise of' are redundant; 'comprise' takes no preposition, while 'comprise of' should be replaced by 'consist of'.

Prepositions: 'cope with', 'comply with', 'conducive to', 'deprived of', 'composed of', 'adapted to', 'averse to', 'capable of', 'eligible for', 'superior to'.

Percentage change: percentage increase = (new - old) / old × 100; a successive increase of a% then b% is equivalent to a + b + ab/100.

Simple interest SI = P × R × T / 100; compound interest CI = P × (1 + R/100)^T - P, compounded annually; for half-yearly compounding, halve the rate and double the time.

Profit and loss: profit% is calculated on cost price by default; selling price = CP × (100 + profit%) / 100; for successive discounts of a% and b%, net discount = a + b - ab/100.

Time, speed and distance: distance = speed × time; average speed for equal distances at speeds x and y is 2xy / (x + y), not (x + y)/2.

Boats and streams: downstream speed = boat speed + stream speed; upstream speed = boat speed - stream speed; boat speed = (downstream + upstream)/2.

Time and work: if A finishes in x days and B in y days, together they take xy/(x + y) days; use the LCM method to express rates as units per day.

Ratio and mixture: alligation rule gives the ratio of two components as (higher - mean) : (mean - lower); repeated replacement leaves final quantity = original × (1 - replaced/total)^n.

Mensuration: area of circle = πr², circumference = 2πr; cylinder volume = πr²h; sphere volume = (4/3)πr³; cone volume = (1/3)πr²h.

Data interpretation: compute the required ratio or percentage directly from the table or graph; convert percentages to fractions (12.5% = 1/8, 16.67% = 1/6, 33.33% = 1/3) to speed up calculation.

In a linear arrangement facing north, a person to the right of another has a higher position number; when facing south, the mapping reverses, so right becomes the lower position number.

For circular seating facing the centre, a person's immediate left is the next position clockwise; when facing outward, immediate left is anticlockwise.

Blood relations: draw a family tree using symbols (+ male, - female, = married, | child) and never assume gender from a name alone; 'brother of my father' is uncle, and 'son of my sister' is nephew.

Syllogism: a conclusion follows only if it is true in every possible Venn diagram of the given statements; 'some A are B' does not imply 'some B are not A'.

Coding-decoding: check letter positions (A=1 to Z=26) for shifts, reversals, or sums; a common pattern is each letter moved by an increasing step.

Inequalities: chain the symbols, then test the conclusion; 'A > B ≥ C' gives A > C but not C > A, and only 'either-or' applies when the pair is complementary and both individually false.

Direction sense: track net displacement with north as +y and east as +x; the shortest distance uses the Pythagorean theorem, and a left turn while facing north points west.

Series completion: check differences of differences, alternate-term patterns, and prime or square multipliers; number series often combine two interleaved sequences.

Puzzles with multiple attributes: start with the most restrictive clue, and use a grid to eliminate options rather than holding all possibilities in memory.

The Reserve Bank of India was established on 1 April 1935 under the RBI Act, 1934, and was nationalised in 1949; it is the monetary authority and regulates banks.

NABARD, established in 1982, is the apex institution for agricultural and rural credit; it refinances cooperatives, RRBs, and rural infrastructure through the Rural Infrastructure Development Fund.

Priority sector lending targets: 40% of adjusted net bank credit for domestic commercial banks, including 18% for agriculture and 7.5% for micro enterprises; RRBs and small finance banks carry a 75% target.

The Kisan Credit Card scheme gives short-term crop loans and was extended to dairy, fishery, and animal husbandry; interest subvention applies to prompt repayment of short-term crop loans.

Pradhan Mantri Fasal Bima Yojana: farmers pay 2% premium for kharif food and oilseed crops, 1.5% for rabi crops, and 5% for commercial and horticultural crops, with the balance subsidised by the government.

Pradhan Mantri Kisan Samman Nidhi provides Rs 6,000 per year in three instalments of Rs 2,000 to eligible landholding farmer families.

Deposit insurance under DICGC covers up to Rs 5 lakh per depositor per bank for both principal and interest.

The Monetary Policy Committee has six members and sets the repo rate; raising the repo rate tightens liquidity, while the reverse repo absorbs liquidity.

Nationalised banks: 14 banks were nationalised in 1969 and 6 more in 1980; regional rural banks were set up in 1975 on the recommendation of the Narasimham Working Group.

Soil pH ranges: strongly acidic <5.5, moderately acidic 5.5-6.5, near neutral 6.6-7.3, alkaline >7.3; most field crops peak between pH 6.0 and 7.5, while tea prefers pH 4.5-5.5 and rice tolerates 5.5-6.5.

N-P-K is expressed as N, P2O5, and K2O: elemental P = P2O5 × 0.44 and elemental K = K2O × 0.83; a 50 kg bag of 10:26:26 supplies 5 kg N, 13 kg P2O5, and 13 kg K2O.

The three primary plant macronutrients are N, P, and K; secondary nutrients are Ca, Mg, and S; the recognized micronutrients are Fe, Mn, Zn, Cu, B, Mo, Cl, and Ni.

Nitrogen is taken up chiefly as nitrate (NO3-) and ammonium (NH4+); it is mobile in the plant, so deficiency appears first as yellowing of older, lower leaves.

Phosphorus deficiency shows as stunted growth with purplish or dark green older leaves; potassium deficiency shows as marginal scorching of older leaves.

Zinc deficiency in rice appears as khaira (brown rusty spots on middle leaves); boron deficiency causes hollow heart in cauliflower and browning in rice.

Legumes fix atmospheric nitrogen through Rhizobium in root nodules; inoculation is recommended when a field has no recent history of the specific legume crop.

Integrated Pest Management follows the sequence: monitor and survey, then cultural and mechanical methods, then biological control, then need-based chemical sprays; the economic threshold level (ETL) is the pest density at which control becomes economically justified.

Drip irrigation saves roughly 40-60% water compared with surface flooding; sprinkler irrigation suits close-growing crops, while drip suits wide-row crops, orchards, and vegetables.

Subject-verb agreement: a singular subject takes a singular verb, but 'one of + plural noun' takes a singular verb, as in 'One of the officers is absent'; collective nouns take a singular verb when acting as a unit.

Common error patterns: 'discuss about' and 'comprise of' are redundant; 'comprise' takes no preposition, while 'comprise of' should be replaced by 'consist of'.

Prepositions: 'cope with', 'comply with', 'conducive to', 'deprived of', 'composed of', 'adapted to', 'averse to', 'capable of', 'eligible for', 'superior to'.

For a reading-comprehension passage, locate the answer sentence rather than relying on outside knowledge; the correct option restates the passage, while distractor options add unsupported claims or reverse the cause-effect relation.

Cloze tests: read the whole passage first, then choose the option that fits both meaning and grammar; check collocation, tense, and article agreement.

Para jumbles: identify the opening sentence (usually general, introducing a subject without pronouns referring back), then chain sentences by pronouns, conjunctions, and repeated keywords.

Synonyms and antonyms should be judged from an example context, because a word such as 'address' can mean to speak, to deal with, or a location.

Time and work: if A finishes in x days and B in y days, together they take xy/(x + y) days; use the LCM method to express rates as units per day.

Ratio and mixture: alligation rule gives the ratio of two components as (higher - mean) : (mean - lower); repeated replacement leaves final quantity = original × (1 - replaced/total)^n.

Mensuration: area of circle = πr², circumference = 2πr; cylinder volume = πr²h; sphere volume = (4/3)πr³; cone volume = (1/3)πr²h.

Data interpretation: compute the required ratio or percentage directly from the table or graph; convert percentages to fractions (12.5% = 1/8, 16.67% = 1/6, 33.33% = 1/3) to speed up calculation.

In a linear arrangement facing north, a person to the right of another has a higher position number; when facing south, the mapping reverses, so right becomes the lower position number.

For circular seating facing the centre, a person's immediate left is the next position clockwise; when facing outward, immediate left is anticlockwise.

Blood relations: draw a family tree using symbols (+ male, - female, = married, | child) and never assume gender from a name alone; 'brother of my father' is uncle, and 'son of my sister' is nephew.

Syllogism: a conclusion follows only if it is true in every possible Venn diagram of the given statements; 'some A are B' does not imply 'some B are not A'.

Coding-decoding: check letter positions (A=1 to Z=26) for shifts, reversals, or sums; a common pattern is each letter moved by an increasing step.

Inequalities: chain the symbols, then test the conclusion; 'A > B ≥ C' gives A > C but not C > A, and only 'either-or' applies when the pair is complementary and both individually false.

Direction sense: track net displacement with north as +y and east as +x; the shortest distance uses the Pythagorean theorem, and a left turn while facing north points west.

Series completion: check differences of differences, alternate-term patterns, and prime or square multipliers; number series often combine two interleaved sequences.

Puzzles with multiple attributes: start with the most restrictive clue, and use a grid to eliminate options rather than holding all possibilities in memory.

The Reserve Bank of India was established on 1 April 1935 under the RBI Act, 1934, and was nationalised in 1949; it is the monetary authority and regulates banks.

NABARD, established in 1982, is the apex institution for agricultural and rural credit; it refinances cooperatives, RRBs, and rural infrastructure through the Rural Infrastructure Development Fund.

Priority sector lending targets: 40% of adjusted net bank credit for domestic commercial banks, including 18% for agriculture and 7.5% for micro enterprises; RRBs and small finance banks carry a 75% target.

The Kisan Credit Card scheme gives short-term crop loans and was extended to dairy, fishery, and animal husbandry; interest subvention applies to prompt repayment of short-term crop loans.

Pradhan Mantri Fasal Bima Yojana: farmers pay 2% premium for kharif food and oilseed crops, 1.5% for rabi crops, and 5% for commercial and horticultural crops, with the balance subsidised by the government.

Pradhan Mantri Kisan Samman Nidhi provides Rs 6,000 per year in three instalments of Rs 2,000 to eligible landholding farmer families.

Deposit insurance under DICGC covers up to Rs 5 lakh per depositor per bank for both principal and interest.

The Monetary Policy Committee has six members and sets the repo rate; raising the repo rate tightens liquidity, while the reverse repo absorbs liquidity.

Nationalised banks: 14 banks were nationalised in 1969 and 6 more in 1980; regional rural banks were set up in 1975 on the recommendation of the Narasimham Working Group.

Soil pH ranges: strongly acidic <5.5, moderately acidic 5.5-6.5, near neutral 6.6-7.3, alkaline >7.3; most field crops peak between pH 6.0 and 7.5, while tea prefers pH 4.5-5.5 and rice tolerates 5.5-6.5.

N-P-K is expressed as N, P2O5, and K2O: elemental P = P2O5 × 0.44 and elemental K = K2O × 0.83; a 50 kg bag of 10:26:26 supplies 5 kg N, 13 kg P2O5, and 13 kg K2O.

The three primary plant macronutrients are N, P, and K; secondary nutrients are Ca, Mg, and S; the recognized micronutrients are Fe, Mn, Zn, Cu, B, Mo, Cl, and Ni.

Nitrogen is taken up chiefly as nitrate (NO3-) and ammonium (NH4+); it is mobile in the plant, so deficiency appears first as yellowing of older, lower leaves.

Phosphorus deficiency shows as stunted growth with purplish or dark green older leaves; potassium deficiency shows as marginal scorching of older leaves.

Zinc deficiency in rice appears as khaira (brown rusty spots on middle leaves); boron deficiency causes hollow heart in cauliflower and browning in rice.

Legumes fix atmospheric nitrogen through Rhizobium in root nodules; inoculation is recommended when a field has no recent history of the specific legume crop.

Integrated Pest Management follows the sequence: monitor and survey, then cultural and mechanical methods, then biological control, then need-based chemical sprays; the economic threshold level (ETL) is the pest density at which control becomes economically justified.

Drip irrigation saves roughly 40-60% water compared with surface flooding; sprinkler irrigation suits close-growing crops, while drip suits wide-row crops, orchards, and vegetables.

Subject-verb agreement: a singular subject takes a singular verb, but 'one of + plural noun' takes a singular verb, as in 'One of the officers is absent'; collective nouns take a singular verb when acting as a unit.

Common error patterns: 'discuss about' and 'comprise of' are redundant; 'comprise' takes no preposition, while 'comprise of' should be replaced by 'consist of'.

Prepositions: 'cope with', 'comply with', 'conducive to', 'deprived of', 'composed of', 'adapted to', 'averse to', 'capable of', 'eligible for', 'superior to'.

For a reading-comprehension passage, locate the answer sentence rather than relying on outside knowledge; the correct option restates the passage, while distractor options add unsupported claims or reverse the cause-effect relation.

Cloze tests: read the whole passage first, then choose the option that fits both meaning and grammar; check collocation, tense, and article agreement.

Para jumbles: identify the opening sentence (usually general, introducing a subject without pronouns referring back), then chain sentences by pronouns, conjunctions, and repeated keywords.

Synonyms and antonyms should be judged from an example context, because a word such as 'address' can mean to speak, to deal with, or a location.

Idioms often appear in error spotting: 'at the drop of a hat' means instantly, 'a bolt from the blue' means a sudden shock, and 'to bell the cat' means to take the risk first.

For sentence improvement, prefer the shortest grammatically correct option; an option that changes the meaning of the original sentence is generally incorrect.

Percentage change: percentage increase = (new - old) / old × 100; a successive increase of a% then b% is equivalent to a + b + ab/100.

Simple interest SI = P × R × T / 100; compound interest CI = P × (1 + R/100)^T - P, compounded annually; for half-yearly compounding, halve the rate and double the time.

Profit and loss: profit% is calculated on cost price by default; selling price = CP × (100 + profit%) / 100; for successive discounts of a% and b%, net discount = a + b - ab/100.

Time, speed and distance: distance = speed × time; average speed for equal distances at speeds x and y is 2xy / (x + y), not (x + y)/2.

For circular seating facing the centre, a person's immediate left is the next position clockwise; when facing outward, immediate left is anticlockwise.

Blood relations: draw a family tree using symbols (+ male, - female, = married, | child) and never assume gender from a name alone; 'brother of my father' is uncle, and 'son of my sister' is nephew.

Syllogism: a conclusion follows only if it is true in every possible Venn diagram of the given statements; 'some A are B' does not imply 'some B are not A'.

Coding-decoding: check letter positions (A=1 to Z=26) for shifts, reversals, or sums; a common pattern is each letter moved by an increasing step.

Inequalities: chain the symbols, then test the conclusion; 'A > B ≥ C' gives A > C but not C > A, and only 'either-or' applies when the pair is complementary and both individually false.

Direction sense: track net displacement with north as +y and east as +x; the shortest distance uses the Pythagorean theorem, and a left turn while facing north points west.

Series completion: check differences of differences, alternate-term patterns, and prime or square multipliers; number series often combine two interleaved sequences.

Puzzles with multiple attributes: start with the most restrictive clue, and use a grid to eliminate options rather than holding all possibilities in memory.

The Reserve Bank of India was established on 1 April 1935 under the RBI Act, 1934, and was nationalised in 1949; it is the monetary authority and regulates banks.

NABARD, established in 1982, is the apex institution for agricultural and rural credit; it refinances cooperatives, RRBs, and rural infrastructure through the Rural Infrastructure Development Fund.

Priority sector lending targets: 40% of adjusted net bank credit for domestic commercial banks, including 18% for agriculture and 7.5% for micro enterprises; RRBs and small finance banks carry a 75% target.

The Kisan Credit Card scheme gives short-term crop loans and was extended to dairy, fishery, and animal husbandry; interest subvention applies to prompt repayment of short-term crop loans.

Pradhan Mantri Fasal Bima Yojana: farmers pay 2% premium for kharif food and oilseed crops, 1.5% for rabi crops, and 5% for commercial and horticultural crops, with the balance subsidised by the government.

Pradhan Mantri Kisan Samman Nidhi provides Rs 6,000 per year in three instalments of Rs 2,000 to eligible landholding farmer families.

Deposit insurance under DICGC covers up to Rs 5 lakh per depositor per bank for both principal and interest.

The Monetary Policy Committee has six members and sets the repo rate; raising the repo rate tightens liquidity, while the reverse repo absorbs liquidity.

Nationalised banks: 14 banks were nationalised in 1969 and 6 more in 1980; regional rural banks were set up in 1975 on the recommendation of the Narasimham Working Group.

Soil pH ranges: strongly acidic <5.5, moderately acidic 5.5-6.5, near neutral 6.6-7.3, alkaline >7.3; most field crops peak between pH 6.0 and 7.5, while tea prefers pH 4.5-5.5 and rice tolerates 5.5-6.5.

N-P-K is expressed as N, P2O5, and K2O: elemental P = P2O5 × 0.44 and elemental K = K2O × 0.83; a 50 kg bag of 10:26:26 supplies 5 kg N, 13 kg P2O5, and 13 kg K2O.

The three primary plant macronutrients are N, P, and K; secondary nutrients are Ca, Mg, and S; the recognized micronutrients are Fe, Mn, Zn, Cu, B, Mo, Cl, and Ni.

Nitrogen is taken up chiefly as nitrate (NO3-) and ammonium (NH4+); it is mobile in the plant, so deficiency appears first as yellowing of older, lower leaves.

Phosphorus deficiency shows as stunted growth with purplish or dark green older leaves; potassium deficiency shows as marginal scorching of older leaves.

Zinc deficiency in rice appears as khaira (brown rusty spots on middle leaves); boron deficiency causes hollow heart in cauliflower and browning in rice.

Legumes fix atmospheric nitrogen through Rhizobium in root nodules; inoculation is recommended when a field has no recent history of the specific legume crop.

Integrated Pest Management follows the sequence: monitor and survey, then cultural and mechanical methods, then biological control, then need-based chemical sprays; the economic threshold level (ETL) is the pest density at which control becomes economically justified.

Drip irrigation saves roughly 40-60% water compared with surface flooding; sprinkler irrigation suits close-growing crops, while drip suits wide-row crops, orchards, and vegetables.

Subject-verb agreement: a singular subject takes a singular verb, but 'one of + plural noun' takes a singular verb, as in 'One of the officers is absent'; collective nouns take a singular verb when acting as a unit.

Common error patterns: 'discuss about' and 'comprise of' are redundant; 'comprise' takes no preposition, while 'comprise of' should be replaced by 'consist of'.

Prepositions: 'cope with', 'comply with', 'conducive to', 'deprived of', 'composed of', 'adapted to', 'averse to', 'capable of', 'eligible for', 'superior to'.

For a reading-comprehension passage, locate the answer sentence rather than relying on outside knowledge; the correct option restates the passage, while distractor options add unsupported claims or reverse the cause-effect relation.

Cloze tests: read the whole passage first, then choose the option that fits both meaning and grammar; check collocation, tense, and article agreement.

Para jumbles: identify the opening sentence (usually general, introducing a subject without pronouns referring back), then chain sentences by pronouns, conjunctions, and repeated keywords.

Synonyms and antonyms should be judged from an example context, because a word such as 'address' can mean to speak, to deal with, or a location.

Idioms often appear in error spotting: 'at the drop of a hat' means instantly, 'a bolt from the blue' means a sudden shock, and 'to bell the cat' means to take the risk first.

For sentence improvement, prefer the shortest grammatically correct option; an option that changes the meaning of the original sentence is generally incorrect.

Percentage change: percentage increase = (new - old) / old × 100; a successive increase of a% then b% is equivalent to a + b + ab/100.

Simple interest SI = P × R × T / 100; compound interest CI = P × (1 + R/100)^T - P, compounded annually; for half-yearly compounding, halve the rate and double the time.

Profit and loss: profit% is calculated on cost price by default; selling price = CP × (100 + profit%) / 100; for successive discounts of a% and b%, net discount = a + b - ab/100.

Time, speed and distance: distance = speed × time; average speed for equal distances at speeds x and y is 2xy / (x + y), not (x + y)/2.

Boats and streams: downstream speed = boat speed + stream speed; upstream speed = boat speed - stream speed; boat speed = (downstream + upstream)/2.

Time and work: if A finishes in x days and B in y days, together they take xy/(x + y) days; use the LCM method to express rates as units per day.

Ratio and mixture: alligation rule gives the ratio of two components as (higher - mean) : (mean - lower); repeated replacement leaves final quantity = original × (1 - replaced/total)^n.

Mensuration: area of circle = πr², circumference = 2πr; cylinder volume = πr²h; sphere volume = (4/3)πr³; cone volume = (1/3)πr²h.

Direction sense: track net displacement with north as +y and east as +x; the shortest distance uses the Pythagorean theorem, and a left turn while facing north points west.

Series completion: check differences of differences, alternate-term patterns, and prime or square multipliers; number series often combine two interleaved sequences.

The Reserve Bank of India was established on 1 April 1935 under the RBI Act, 1934, and was nationalised in 1949; it is the monetary authority and regulates banks.

NABARD, established in 1982, is the apex institution for agricultural and rural credit; it refinances cooperatives, RRBs, and rural infrastructure through the Rural Infrastructure Development Fund.

Priority sector lending targets: 40% of adjusted net bank credit for domestic commercial banks, including 18% for agriculture and 7.5% for micro enterprises; RRBs and small finance banks carry a 75% target.

The Kisan Credit Card scheme gives short-term crop loans and was extended to dairy, fishery, and animal husbandry; interest subvention applies to prompt repayment of short-term crop loans.

Pradhan Mantri Fasal Bima Yojana: farmers pay 2% premium for kharif food and oilseed crops, 1.5% for rabi crops, and 5% for commercial and horticultural crops, with the balance subsidised by the government.

Pradhan Mantri Kisan Samman Nidhi provides Rs 6,000 per year in three instalments of Rs 2,000 to eligible landholding farmer families.

Deposit insurance under DICGC covers up to Rs 5 lakh per depositor per bank for both principal and interest.

The Monetary Policy Committee has six members and sets the repo rate; raising the repo rate tightens liquidity, while the reverse repo absorbs liquidity.

Nationalised banks: 14 banks were nationalised in 1969 and 6 more in 1980; regional rural banks were set up in 1975 on the recommendation of the Narasimham Working Group.

Soil pH ranges: strongly acidic <5.5, moderately acidic 5.5-6.5, near neutral 6.6-7.3, alkaline >7.3; most field crops peak between pH 6.0 and 7.5, while tea prefers pH 4.5-5.5 and rice tolerates 5.5-6.5.

N-P-K is expressed as N, P2O5, and K2O: elemental P = P2O5 × 0.44 and elemental K = K2O × 0.83; a 50 kg bag of 10:26:26 supplies 5 kg N, 13 kg P2O5, and 13 kg K2O.

The three primary plant macronutrients are N, P, and K; secondary nutrients are Ca, Mg, and S; the recognized micronutrients are Fe, Mn, Zn, Cu, B, Mo, Cl, and Ni.

Nitrogen is taken up chiefly as nitrate (NO3-) and ammonium (NH4+); it is mobile in the plant, so deficiency appears first as yellowing of older, lower leaves.

Phosphorus deficiency shows as stunted growth with purplish or dark green older leaves; potassium deficiency shows as marginal scorching of older leaves.

Zinc deficiency in rice appears as khaira (brown rusty spots on middle leaves); boron deficiency causes hollow heart in cauliflower and browning in rice.

Legumes fix atmospheric nitrogen through Rhizobium in root nodules; inoculation is recommended when a field has no recent history of the specific legume crop.

Integrated Pest Management follows the sequence: monitor and survey, then cultural and mechanical methods, then biological control, then need-based chemical sprays; the economic threshold level (ETL) is the pest density at which control becomes economically justified.

Drip irrigation saves roughly 40-60% water compared with surface flooding; sprinkler irrigation suits close-growing crops, while drip suits wide-row crops, orchards, and vegetables.

Subject-verb agreement: a singular subject takes a singular verb, but 'one of + plural noun' takes a singular verb, as in 'One of the officers is absent'; collective nouns take a singular verb when acting as a unit.

Common error patterns: 'discuss about' and 'comprise of' are redundant; 'comprise' takes no preposition, while 'comprise of' should be replaced by 'consist of'.

Prepositions: 'cope with', 'comply with', 'conducive to', 'deprived of', 'composed of', 'adapted to', 'averse to', 'capable of', 'eligible for', 'superior to'.

For a reading-comprehension passage, locate the answer sentence rather than relying on outside knowledge; the correct option restates the passage, while distractor options add unsupported claims or reverse the cause-effect relation.

Cloze tests: read the whole passage first, then choose the option that fits both meaning and grammar; check collocation, tense, and article agreement.

Para jumbles: identify the opening sentence (usually general, introducing a subject without pronouns referring back), then chain sentences by pronouns, conjunctions, and repeated keywords.

Synonyms and antonyms should be judged from an example context, because a word such as 'address' can mean to speak, to deal with, or a location.

Idioms often appear in error spotting: 'at the drop of a hat' means instantly, 'a bolt from the blue' means a sudden shock, and 'to bell the cat' means to take the risk first.

For sentence improvement, prefer the shortest grammatically correct option; an option that changes the meaning of the original sentence is generally incorrect.

Percentage change: percentage increase = (new - old) / old × 100; a successive increase of a% then b% is equivalent to a + b + ab/100.

Simple interest SI = P × R × T / 100; compound interest CI = P × (1 + R/100)^T - P, compounded annually; for half-yearly compounding, halve the rate and double the time.

Profit and loss: profit% is calculated on cost price by default; selling price = CP × (100 + profit%) / 100; for successive discounts of a% and b%, net discount = a + b - ab/100.

Time, speed and distance: distance = speed × time; average speed for equal distances at speeds x and y is 2xy / (x + y), not (x + y)/2.

Boats and streams: downstream speed = boat speed + stream speed; upstream speed = boat speed - stream speed; boat speed = (downstream + upstream)/2.

Time and work: if A finishes in x days and B in y days, together they take xy/(x + y) days; use the LCM method to express rates as units per day.

Ratio and mixture: alligation rule gives the ratio of two components as (higher - mean) : (mean - lower); repeated replacement leaves final quantity = original × (1 - replaced/total)^n.

Mensuration: area of circle = πr², circumference = 2πr; cylinder volume = πr²h; sphere volume = (4/3)πr³; cone volume = (1/3)πr²h.

Data interpretation: compute the required ratio or percentage directly from the table or graph; convert percentages to fractions (12.5% = 1/8, 16.67% = 1/6, 33.33% = 1/3) to speed up calculation.

In a linear arrangement facing north, a person to the right of another has a higher position number; when facing south, the mapping reverses, so right becomes the lower position number.

For circular seating facing the centre, a person's immediate left is the next position clockwise; when facing outward, immediate left is anticlockwise.

Blood relations: draw a family tree using symbols (+ male, - female, = married, | child) and never assume gender from a name alone; 'brother of my father' is uncle, and 'son of my sister' is nephew.

Syllogism: a conclusion follows only if it is true in every possible Venn diagram of the given statements; 'some A are B' does not imply 'some B are not A'.

Coding-decoding: check letter positions (A=1 to Z=26) for shifts, reversals, or sums; a common pattern is each letter moved by an increasing step.

The Kisan Credit Card scheme gives short-term crop loans and was extended to dairy, fishery, and animal husbandry; interest subvention applies to prompt repayment of short-term crop loans.

Pradhan Mantri Fasal Bima Yojana: farmers pay 2% premium for kharif food and oilseed crops, 1.5% for rabi crops, and 5% for commercial and horticultural crops, with the balance subsidised by the government.

Pradhan Mantri Kisan Samman Nidhi provides Rs 6,000 per year in three instalments of Rs 2,000 to eligible landholding farmer families.

Deposit insurance under DICGC covers up to Rs 5 lakh per depositor per bank for both principal and interest.

The Monetary Policy Committee has six members and sets the repo rate; raising the repo rate tightens liquidity, while the reverse repo absorbs liquidity.

Nationalised banks: 14 banks were nationalised in 1969 and 6 more in 1980; regional rural banks were set up in 1975 on the recommendation of the Narasimham Working Group.

Soil pH ranges: strongly acidic <5.5, moderately acidic 5.5-6.5, near neutral 6.6-7.3, alkaline >7.3; most field crops peak between pH 6.0 and 7.5, while tea prefers pH 4.5-5.5 and rice tolerates 5.5-6.5.

N-P-K is expressed as N, P2O5, and K2O: elemental P = P2O5 × 0.44 and elemental K = K2O × 0.83; a 50 kg bag of 10:26:26 supplies 5 kg N, 13 kg P2O5, and 13 kg K2O.

The three primary plant macronutrients are N, P, and K; secondary nutrients are Ca, Mg, and S; the recognized micronutrients are Fe, Mn, Zn, Cu, B, Mo, Cl, and Ni.

Nitrogen is taken up chiefly as nitrate (NO3-) and ammonium (NH4+); it is mobile in the plant, so deficiency appears first as yellowing of older, lower leaves.

Phosphorus deficiency shows as stunted growth with purplish or dark green older leaves; potassium deficiency shows as marginal scorching of older leaves.

Zinc deficiency in rice appears as khaira (brown rusty spots on middle leaves); boron deficiency causes hollow heart in cauliflower and browning in rice.

Legumes fix atmospheric nitrogen through Rhizobium in root nodules; inoculation is recommended when a field has no recent history of the specific legume crop.

Integrated Pest Management follows the sequence: monitor and survey, then cultural and mechanical methods, then biological control, then need-based chemical sprays; the economic threshold level (ETL) is the pest density at which control becomes economically justified.

Drip irrigation saves roughly 40-60% water compared with surface flooding; sprinkler irrigation suits close-growing crops, while drip suits wide-row crops, orchards, and vegetables.

Subject-verb agreement: a singular subject takes a singular verb, but 'one of + plural noun' takes a singular verb, as in 'One of the officers is absent'; collective nouns take a singular verb when acting as a unit.

Common error patterns: 'discuss about' and 'comprise of' are redundant; 'comprise' takes no preposition, while 'comprise of' should be replaced by 'consist of'.

Prepositions: 'cope with', 'comply with', 'conducive to', 'deprived of', 'composed of', 'adapted to', 'averse to', 'capable of', 'eligible for', 'superior to'.

For a reading-comprehension passage, locate the answer sentence rather than relying on outside knowledge; the correct option restates the passage, while distractor options add unsupported claims or reverse the cause-effect relation.

Cloze tests: read the whole passage first, then choose the option that fits both meaning and grammar; check collocation, tense, and article agreement.

Para jumbles: identify the opening sentence (usually general, introducing a subject without pronouns referring back), then chain sentences by pronouns, conjunctions, and repeated keywords.

Synonyms and antonyms should be judged from an example context, because a word such as 'address' can mean to speak, to deal with, or a location.

Idioms often appear in error spotting: 'at the drop of a hat' means instantly, 'a bolt from the blue' means a sudden shock, and 'to bell the cat' means to take the risk first.

For sentence improvement, prefer the shortest grammatically correct option; an option that changes the meaning of the original sentence is generally incorrect.

Percentage change: percentage increase = (new - old) / old × 100; a successive increase of a% then b% is equivalent to a + b + ab/100.

Simple interest SI = P × R × T / 100; compound interest CI = P × (1 + R/100)^T - P, compounded annually; for half-yearly compounding, halve the rate and double the time.

Profit and loss: profit% is calculated on cost price by default; selling price = CP × (100 + profit%) / 100; for successive discounts of a% and b%, net discount = a + b - ab/100.

Time, speed and distance: distance = speed × time; average speed for equal distances at speeds x and y is 2xy / (x + y), not (x + y)/2.

Boats and streams: downstream speed = boat speed + stream speed; upstream speed = boat speed - stream speed; boat speed = (downstream + upstream)/2.

Time and work: if A finishes in x days and B in y days, together they take xy/(x + y) days; use the LCM method to express rates as units per day.

Ratio and mixture: alligation rule gives the ratio of two components as (higher - mean) : (mean - lower); repeated replacement leaves final quantity = original × (1 - replaced/total)^n.

Mensuration: area of circle = πr², circumference = 2πr; cylinder volume = πr²h; sphere volume = (4/3)πr³; cone volume = (1/3)πr²h.

Data interpretation: compute the required ratio or percentage directly from the table or graph; convert percentages to fractions (12.5% = 1/8, 16.67% = 1/6, 33.33% = 1/3) to speed up calculation.

In a linear arrangement facing north, a person to the right of another has a higher position number; when facing south, the mapping reverses, so right becomes the lower position number.

For circular seating facing the centre, a person's immediate left is the next position clockwise; when facing outward, immediate left is anticlockwise.

Blood relations: draw a family tree using symbols (+ male, - female, = married, | child) and never assume gender from a name alone; 'brother of my father' is uncle, and 'son of my sister' is nephew.

Syllogism: a conclusion follows only if it is true in every possible Venn diagram of the given statements; 'some A are B' does not imply 'some B are not A'.

Coding-decoding: check letter positions (A=1 to Z=26) for shifts, reversals, or sums; a common pattern is each letter moved by an increasing step.

Inequalities: chain the symbols, then test the conclusion; 'A > B ≥ C' gives A > C but not C > A, and only 'either-or' applies when the pair is complementary and both individually false.

Direction sense: track net displacement with north as +y and east as +x; the shortest distance uses the Pythagorean theorem, and a left turn while facing north points west.

Series completion: check differences of differences, alternate-term patterns, and prime or square multipliers; number series often combine two interleaved sequences.

Puzzles with multiple attributes: start with the most restrictive clue, and use a grid to eliminate options rather than holding all possibilities in memory.

The Reserve Bank of India was established on 1 April 1935 under the RBI Act, 1934, and was nationalised in 1949; it is the monetary authority and regulates banks.
