32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Syllogism particular conclusion
- A particular premise ('some') forces a particular conclusion; 'All A are B' plus 'Some B are C' does not prove 'All A are C'.
- Circular arrangement facing centre
- When people face the centre, a person's left is clockwise and right is anticlockwise; reverse this when they face outward.
- Inequality chain rule
- Combine symbols in order: A > B ≥ C means A > C. A conclusion is valid only if the same direction of inequality links the two entities.
- Rank from both ends
- Total number of people equals rank from left plus rank from right minus one, because the counted person is included twice.
- Data sufficiency test
- A statement is sufficient only if it produces exactly one definite answer. Two conflicting unique answers from separate statements indicate inconsistent data.
- Blood relation gender markers
- Use plus for male and minus for female in a generation-wise tree; never infer gender from a name or from a relationship word such as 'cousin'.
- Direction sense displacement
- Track east-west and north-south movement as coordinates; shortest distance back to start equals the square root of the sum of squares.
- Coding-decoding letter positions
- Assign A=1 through Z=26 and test forward or reverse shifts between the coded and original word before trying substitution patterns.
- Compound interest formula
- Amount equals principal multiplied by (1 + rate/100) raised to the time in years; compound interest is that amount minus the principal.
- CI minus SI two years
- For two years, the gap between compound and simple interest equals principal multiplied by the square of rate divided by 100.
- Successive discount formula
- Two successive discounts of a and b percent equal a single discount of a + b − ab/100 percent, always less than the simple sum.
- km/h to m/s
- Multiply a speed in kilometres per hour by 5/18 to convert it to metres per second; multiply by 18/5 for the reverse.
- Boat and stream speeds
- Downstream speed is boat plus stream and upstream is boat minus stream; boat speed is their average and stream speed is half their difference.
- Alligation ratio rule
- Ratio of two mixed quantities equals the difference between the mean and the cheaper price to the difference between the dearer price and the mean.
- Permutation versus combination
- Permutations count ordered arrangements using n!/(n−r)!; combinations count unordered selections using n!/(r!(n−r)!). Order decides which applies.
- Relative speed rule
- When two bodies move towards each other their speeds add; when they move in the same direction the difference of speeds is used.
- Weighted average formula
- The weighted average equals the sum of each value multiplied by its weight, divided by the total of all weights.
- Profit and loss selling price
- Selling price equals cost price multiplied by (100 + profit percent) divided by 100; use 100 minus loss percent when a loss occurs.
- One of plus plural noun
- In 'one of the + plural noun', the verb agrees with 'one' and stays singular, as in 'one of the boys is absent'.
- Each every either neither
- These words are grammatically singular and take a singular verb and singular pronoun, even when followed by 'of' plus a plural noun.
- Prepositions of time
- Use 'in' for months, years and seasons, 'on' for days and dates, and 'at' for clock times, noon and night.
- Since and for usage
- 'Since' marks a starting point in time and 'for' marks a duration; both pair with present perfect or present perfect continuous tenses.
- Correlative parallelism
- After 'not only…but also' and 'either…or', the linked elements must share the same grammatical form, such as both nouns or both clauses.
- Reading comprehension extreme options
- Options containing absolute words such as always, never or only are usually wrong unless the passage explicitly states that absolute claim.
- Para jumble opening sentence
- The first sentence is usually independent and introduces the topic without pronouns or demonstratives that refer to earlier text.
- Cloze connector clues
- Connectors signal the blank's meaning: although shows contrast, therefore shows result, and moreover shows addition of a similar idea.
- RBI establishment facts
- The Reserve Bank of India was set up on 1 April 1935 under the RBI Act 1934, nationalised in 1949, with headquarters in Mumbai.
- Monetary Policy Committee target
- The six-member MPC targets consumer price inflation of 4 percent, with a tolerance band of 2 to 6 percent.
- CRR versus SLR
- CRR is the share of net demand and time liabilities held as cash with RBI; SLR is held in approved securities such as government bonds.
- Repo and reverse repo
