LIC AAO cheat sheet

Syllogism: 'All A are B' converts only to 'Some B are A'; 'No A is B' converts to 'No B is A'; 'Some A are B' converts to 'Some B are A'.

Coded inequality: symbols follow a fixed priority chain (e.g. A > B ≥ C = D). Combine only when the same symbol direction is preserved; a conclusion is false when it demands a strict relation across a '≥' or '≤' link.

Blood relations: draw a tree, not prose. Vertical line = parent-child generation, horizontal double line = siblings/marriage. Solve from the fixed anchor person outward.

Seating arrangement: fix the number of seats first (linear or circular). In a circle facing centre, left = clockwise; facing outward, left = anticlockwise.

Puzzles with multiple attributes: build a grid (persons × attributes) and fill forced cells first; eliminate one option per clue rather than guessing full arrangements.

Direction sense: net displacement = square root of (sum of east-west)² + (sum of north-south)²; final facing direction depends on total right/left turns mod 4.

Alphanumeric series: count positions from the left and right together; left position + right position = total + 1 for the same element.

Input-output and machine logic: identify the invariant rule (sorting, shifting, arithmetic) from step 1 to step 2, then apply it to the new input rather than memorising steps.

Data sufficiency: test each statement alone first; if either alone suffices, the answer is that statement alone - never combine statements before checking independence.

Percentage change: successive changes of a% and b% give net change = a + b + ab/100; a rise of a% then fall of a% gives a net fall of a²/100.

Profit and loss: SP = CP × (100 + profit%)/100. Two articles sold at the same price with equal profit% and loss% always produce a net loss of (x/10)² percent.

Simple and compound interest: CI − SI for 2 years = P(r/100)²; for 3 years = P(r/100)²(3 + r/100).

Time, speed, distance: if speeds are a and b over equal distances, average speed = 2ab/(a + b). Trains crossing each other add speeds; crossing a pole uses own length only.

Boats and streams: downstream = b + s, upstream = b − s, so boat speed = (D + U)/2 and stream speed = (D − U)/2.

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

Mixtures and alligation: ratio of quantities = (mean price − cheaper)/(dearer − mean price); repeated replacement reduces pure quantity by P(1 − x/V)^n.

Permutation and combination: arrangements of n distinct items = n!; selections = nCr = n!/(r!(n−r)!); circular arrangement of n people = (n − 1)!.

Mensuration: cylinder volume = πr²h, cone = (1/3)πr²h, sphere surface = 4πr²; a sphere of radius r recast into a cylinder conserves volume, not surface area.

Subject-verb agreement: 'one of the + plural noun' takes a singular verb; 'each/every/either/neither' takes a singular verb; 'none' agrees with the noun it refers to.

Articles: 'a' before consonant sounds, 'an' before vowel sounds (an hour, a university); 'the' with superlatives, unique objects, and rivers/ranges.

Prepositions with fixed collocations: 'comply with', 'averse to', 'capable of', 'deprived of', 'insist on', 'prefer to', 'superior to' - no 'than' after superior/inferior.

Tenses in reported speech: present becomes past, past becomes past perfect, 'will' becomes 'would'; time markers shift (now → then, today → that day).

Conditional sentences: Type 2 uses past simple in the if-clause with 'would + base verb'; Type 3 uses past perfect with 'would have + past participle'.

Reading comprehension: answer only from the passage. Extreme words (always, never, only) in an option usually signal a wrong inference; 'cannot be determined' is valid when the passage is silent.

Cloze test: decide the part of speech needed from the blank's surroundings, then check collocation and tone (positive/negative) before picking.

Para jumbles: find the opening sentence (introduces the subject without pronouns), then chain by pronouns, connectors, and chronological or cause-effect markers.

Error spotting: check each segment independently for subject-verb, tense, article, and preposition errors; a sentence may be error-free, so 'no error' is a real option.

RBI was established on 1 April 1935 under the RBI Act 1934, nationalised in 1949; headquarters in Mumbai; it issues currency and manages monetary policy.

Nationalised banks: 14 banks nationalised in 1969, 6 in 1980; Regional Rural Banks created in 1975 on the recommendation of the Narasimham Working Group.

Nobel Prize categories are five under the 1895 will (Physics, Chemistry, Medicine, Literature, Peace); Economics was added in 1968 by Sveriges Riksbank.

Indian geography: Tropic of Cancer passes through eight states; the Western Ghats run parallel to the west coast from Gujarat to Kerala.

Fundamental Duties were added by the 42nd Amendment (1976) on the Swaran Singh Committee's recommendation, in Part IVA (Article 51A).

IRDAI was set up in 1999 and became a statutory regulator in 2000 under the IRDA Act; headquarters in Hyderabad.

Life insurance is a contract of indemnity only in the sense of sum assured; general insurance is strictly a contract of indemnity, life insurance is not.
