MSC Bank Recruitment cheat sheet

Subject-verb agreement: a singular subject takes a singular verb; intervening phrases (with, along with, as well as, together with) do not change the number of the subject.

Neither/nor and either/or follow the proximity rule: the verb agrees with the nearer subject, e.g. 'Neither the clerks nor the manager was present.'

Collective nouns (committee, jury, team) take a singular verb when acting as one unit and a plural verb when members act individually.

'Since' marks a point of time; 'for' marks a duration. 'He has worked here since 2019 for six years' is the correct pairing.

Articles: 'a' before consonant sounds (a university, a one-rupee coin), 'an' before vowel sounds (an hour, an MBA, an honest officer).

Cloze tests: read the whole passage first, then choose the option that fits both meaning and grammar; eliminate options that break collocation (e.g. 'make a decision', not 'do a decision').

Common error pairs: 'lie/lay', 'affect/effect', 'principal/principle', 'complement/compliment', 'stationary/stationery'.

Reading comprehension answers must be supported by the passage; options that are true in general but not stated in the text are distractors.

Percentage change: change = (new - old)/old × 100. Successive changes of a% and b% give a net change of a + b + ab/100 percent.

Simple interest SI = P × R × T / 100. Compound interest CI = P[(1 + R/100)^T - 1]; for two years CI - SI = P(R/100)^2.

Profit and loss: profit% = (SP - CP)/CP × 100. If SP is the same and gains and losses are equal in percent, the net result is always a loss of (x/10)^2 percent.

Speed: distance = speed × time. Convert km/h to m/s by multiplying by 5/18; m/s to km/h by multiplying by 18/5.

Ratio and proportion: if a:b = c:d then ad = bc. For partnership, profit shares are proportional to capital × time.

Averages: new average after adding a value = (old sum + value)/new count. For consecutive numbers, average = (first + last)/2.

Time and work: if A does a job in x days and B in y days, together they take xy/(x + y) days. Use LCM of days as total work units.

Coding-decoding: check letter positions (A=1 ... Z=26) and shifts; opposite letter pairs sum to 27 (A-Z, B-Y, C-X).

Direction sense: fix north at the top; net displacement uses Pythagoras when movements are perpendicular, e.g. 3 km north then 4 km east gives 5 km.

Seating arrangement: for a circle facing the centre, 'left' is clockwise and 'right' is anticlockwise; reverse this when facing outward.

Series: check differences, then ratios, then alternate-term patterns, then squares/cubes plus a constant, before assuming a random rule.

Inequality: 'A ≥ B > C' implies A > C and A ≥ C; only the conclusion that is certainly true in every case is valid.

Statement-assumption and statement-course of action questions: an assumption is what the author silently takes for granted, not what is stated explicitly.

Idioms commonly tested: 'at the eleventh hour' means at the last moment; 'to burn the midnight oil' means to work late; 'a white elephant' means a costly, useless possession.

Sentence connectors: 'although' and 'though' contrast; 'therefore' and 'hence' show result; 'moreover' and 'furthermore' add information; 'nevertheless' concedes.

Para jumbles: find the opening sentence that introduces the topic without a pronoun referring backwards, then follow pronoun and connector links to order the rest.

Spelling and usage traps: 'accommodation', 'occurrence', 'embarrass', 'recommend', 'maintenance', 'privilege', 'questionnaire'.

Mixtures and alligation: ratio of quantities = (mean price - cheaper price) : (dearer price - mean price). Repeated replacement leaves P(1 - x/P)^n of the original.

Pipes and cisterns: a filling pipe is positive work, a draining pipe negative; combined rate = 1/a - 1/b, and time = 1/(combined rate).

Simple interest doubles a sum in 100/R years; it triples in 200/R years; at compound interest, money doubles in approximately 72/R years (rule of 72).

Probability: P(E) = favourable outcomes/total outcomes; P(E) + P(not E) = 1; for independent events, P(A and B) = P(A) × P(B).

Number system: divisibility by 3 or 9 depends on digit sum; by 4 on the last two digits; by 8 on the last three digits; by 11 on the alternating digit sum.

Data interpretation: compute the percentage share of each item before comparing; avoid recomputing full values when only ratios are asked.

Puzzles with multiple variables: build a grid, mark definite placements first, and use 'either/or' clues to create two branches that are tested against later clues.

Input-output reasoning: track how elements are rearranged step by step (often smallest number first, then word alphabetically); the rule repeats until sorted.

Alphanumeric series: separate letters, digits and symbols into positions; questions ask for the element n places from an end after a stated rearrangement.

Coded inequalities: define each symbol's meaning in words before evaluating; conclusions must hold in all possible arrangements of the given statement.
