32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Syllogism 'some' rule

A 'some' premise cannot support an 'all' conclusion. Two particular premises never yield a definite conclusion, and a conclusion with a term absent from the premises never follows.

Circular seating left/right

When people face the centre, a person's left neighbour sits clockwise from them and the right neighbour anticlockwise. When they face outward, both directions reverse.

Rank formula

Total number of people equals rank from the top plus rank from the bottom minus one. Use it when a single person's position is given from both ends of a row.

Inequality chain validity

Relations combine only when the inequality signs point the same way. In 'A > B >= C', A > C is valid; in 'A > B < C', no relation between A and C can be concluded.

Direction displacement

Track movement as coordinate pairs, adding for East and North and subtracting for West and South. Final straight-line distance is the square root of the sum of squared net displacements.

Blood relation 'only son'

'Only son of X' means X has exactly one male child and no other sons. 'Only child' is stronger: the person has no siblings at all, which fixes the generation link.

Coding with letter positions

Number letters A to Z as 1 to 26. A constant shift means addition or subtraction; a mirror code pairs letters summing to 27, so A maps to Z and B to Y.

Input-output shifting pattern

In machine input questions, compare successive steps to identify whether numbers are sorted ascending, words alphabetically, or both alternately, then apply the same rule to the final step.

Subject-verb agreement trap

A verb agrees with the actual subject, not with a noun in a phrase between them. In 'The list of items is long', the singular 'list' governs 'is'.

Para jumble opening sentence

The first sentence usually introduces a full noun with no pronoun, definite article or backward reference. Sentences starting with 'this', 'he' or 'therefore' almost never open the paragraph.

Connector meaning pairs

'Although' and 'yet' mark contrast; 'because' and 'hence' mark cause and result; 'unless' means 'if not'. Matching the logical relation eliminates most options quickly.

Idiom: bolt from the blue

A completely unexpected and usually shocking event, like lightning from a clear sky. It describes surprise, not speed, and is used for bad news.

Idiom: let cat out of bag

To reveal a secret, often accidentally. The idiom concerns disclosure of hidden information, not escape or carelessness with possessions.

Reading comprehension inference limit

An inference must follow necessarily from stated facts. Options that are plausible in real life but not supported by the passage are wrong, however true they sound.

Cloze blank part of speech

Decide whether the blank needs a noun, verb, adjective or adverb before reading options. Grammar alone often removes two or three choices without needing full meaning.

Successive percentage change

Two successive changes of a% and b% equal a single change of a + b + ab/100 percent. A rise then equal fall always gives a net decrease, never zero.

CI minus SI two years

For two years the difference between compound and simple interest equals P times (R/100) squared, where P is principal and R the annual rate. For three years it also involves the cube term.

Train crossing platform

Time to cross a platform equals train length plus platform length, divided by speed. Convert km/h to m/s by multiplying by 5/18 before dividing.

Boat and stream speeds

Downstream is boat plus stream, upstream is boat minus stream. Boat speed is half the sum and stream speed half the difference of the two given speeds.

Two-person work formula

If A alone takes x days and B alone takes y days, together they take xy/(x + y) days. Taking the LCM of x and y as total work avoids fractional units.

Alligation ratio rule

The ratio of two mixed quantities equals the difference between the mean and the cheaper value, to the difference between the dearer and the mean.

Equal gain and loss trap

Two articles sold at the same price, one at gain% and one at the same loss%, always produce a net loss of gain squared divided by 100 percent.

Circular permutation

The number of ways to arrange n distinct people around a circle is (n - 1) factorial, because rotations are treated as identical and only relative order matters.

Average after adding a value

The new average equals the old average times the original count, plus the added value, all divided by the new count of items.

Repo rate

The rate at which the RBI lends short-term funds to banks against government securities. Raising it tightens liquidity and is used to control inflation.

CRR versus SLR

CRR is the share of net demand and time liabilities held as cash with the RBI and earns no interest. SLR is held in approved securities and earns interest.

Inflation targeting framework

Since 2016 the RBI targets consumer price inflation of 4 percent, with a tolerance band of 2 to 6 percent, set by a six-member Monetary Policy Committee.

DICGC deposit insurance

Deposit Insurance and Credit Guarantee Corporation insures each depositor up to 5 lakh rupees per bank, covering principal and interest across all deposits in that bank.

NPA 90-day rule

A loan becomes a non-performing asset when interest or principal is overdue for more than 90 days. It is then classified substandard, doubtful or loss.

Basel III capital ratios

Minimum common equity tier 1 is 4.5 percent of risk-weighted assets and total capital adequacy 8 percent. Adding the 2.5 percent conservation buffer gives 10.5 percent.

RTGS versus NEFT

RTGS settles high-value payments individually and in real time with no upper limit but a 2 lakh rupee minimum. NEFT settles in batches with no minimum amount.

Priority sector lending target

Banks must lend 40 percent of adjusted net bank credit to priority sectors, including 18 percent to agriculture and 7.5 percent to micro enterprises.
