SRCC GBO cheat sheet

Reading comprehension: locate the main idea, author's tone, and inference separately; answers to inference questions must be supported by the passage, not by outside knowledge.

Common error-spotting traps: subject-verb agreement with collective nouns, misplaced modifiers, and pronoun-antecedent mismatch; check each clause's subject before the verb.

Standard idiom pairs tested in this exam include 'not only...but also', 'no sooner...than', 'hardly...when', 'scarcely...when', and 'either...or'; keep the parallel structure intact.

Active to passive conversion: object becomes subject, verb becomes 'be + past participle', and the agent is introduced with 'by'; tense of the original must be preserved.

Direct to indirect speech: shift present to past, 'today' to 'that day', 'tomorrow' to 'the next day', and 'this' to 'that' when the reporting verb is past.

Synonyms and antonyms are best answered by substituting the option into the original sentence and checking whether the meaning and register still fit.

Para jumbles: find the opening sentence (usually a general statement with no pronoun referring backward), then chain sentences by pronoun and connector clues such as 'however' and 'therefore'.

One-word substitutions and spelling questions reward knowledge of Latin/Greek roots: 'bene' (good), 'mal' (bad), 'anti' (against), 'circum' (around).

Percentage change: successive changes of a% then b% give a net change of a + b + ab/100 percent; a rise then equal fall always leaves a net decrease.

Simple interest = P x R x T / 100; compound interest = P(1 + R/100)^T - P, with half-yearly compounding using R/2 and 2T periods.

Profit and loss: profit% is calculated on cost price unless stated otherwise; selling price = CP x (100 + profit%)/100; discount% is calculated on marked price.

Time-speed-distance: speed = distance/time; to convert km/h to m/s multiply by 5/18; for a train crossing a platform, total distance = train length + platform length.

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 avoid fractions.

Averages: new average after adding a value = (old sum + value)/(old count + 1); for consecutive numbers the average equals the middle term.

Permutation vs combination: arrangements use nPr = n!/(n-r)!; selections use nCr = n!/[r!(n-r)!]; 'at least one' is often easier as 1 minus 'none'.

Mensuration: area of circle = pi r^2, circumference = 2 pi r; volume of cylinder = pi r^2 h; volume of cone = (1/3) pi r^2 h; sphere volume = (4/3) pi r^3.

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

Blood relations: draw a family tree with gender markers and generation levels; 'brother of my father' is uncle, 'son of my grandfather's only son' is self or brother.

Direction sense: track net displacement with a coordinate grid; final distance uses Pythagoras when the path turns at right angles.

Series completion: check differences, then ratios, then alternating or prime-based patterns; letter series often skip a fixed number of positions in the alphabet.

Coding-decoding: compute the positional shift between plain and coded letters; the same shift usually applies to every letter or alternates between odd and even positions.

Data interpretation: read the axis units and the year labels before computing; percentage share = (part/whole) x 100, and growth rate = (new - old)/old x 100.

Seating arrangement: fix the confirmed position first, then place people relative to it; circular arrangements have (n-1)! distinct orders when rotations are treated as identical.

Statement-assumption and cause-effect questions: reject options that restate the statement or that introduce information absent from the passage.

Reserve Bank of India: established 1935, nationalised 1949, headquartered in Mumbai; it sets the repo rate, and the Monetary Policy Committee has six members and meets at least four times a year.

Repo rate is the rate at which RBI lends to banks against securities; reverse repo is the rate at which RBI absorbs liquidity; CRR and SLR are reserve ratios banks must maintain.

GDP is the market value of final goods and services produced within a country in a year; GNP = GDP + net factor income from abroad.

Inflation measures: CPI tracks retail prices, WPI tracks wholesale prices; demand-pull inflation arises from excess demand, cost-push from rising input costs.

Company forms: a private limited company needs a minimum of 2 members and a public limited company 7; maximum members are 200 and unlimited respectively under the Companies Act, 2013.

Business terminology: 'blue chip' means a large, established, financially sound company; 'bear' expects prices to fall, 'bull' expects prices to rise; IPO is a first public share issue.

Indian economy: the Green Revolution is associated with M. S. Swaminathan and wheat; the White Revolution with Verghese Kurien and milk; NABARD is the apex development bank for agriculture.

International institutions: IMF handles balance-of-payments support, the World Bank funds development projects, and WTO administers global trade rules; India is a founding member of all three.
