Quantitative Aptitude for LIC AAO

Prelims' Quant, and Mains' 'Data Analysis & Interpretation' section.

📊 Prelims: 35 Q / 35 marks · Mains: 30 Q / 90 marks

How toppers play this section

Mains' framing as 'Data Analysis & Interpretation' signals a DI-heavy question mix layered on top of the standard arithmetic/algebra toolkit — the full IBPS-PO-shared quant syllabus prepares for both stages.

Chapters

Built to the LIC AAO blueprint — notes, shortcuts, solved PYQ-style examples and practice in every chapter.

1Data Interpretation (Table, Bar, Line, Pie, Caselet)The whole quant section in disguise. 30–50% of every IBPS PO quant paper is DI — and DI is just percentage, ratio and average applied to a chart. Learn to read the chart before the question, choose the base correctly, and approximate ruthlessly, and a 5-question set becomes five fast, near-certain marks.⏱ 25 min read

2Simplification & ApproximationThe fastest, most certain marks in the quant section — 5–10 questions in Prelims that a trained hand clears in under 30 seconds each. Master BODMAS discipline, the fraction–percentage table, and a handful of squaring/multiplication tricks, and you bank a block of guaranteed marks that buys time for the heavier DI.⏱ 20 min read

3Number Series — Missing & Wrong Term3–5 fast, high-accuracy marks in every paper — once you can spot the pattern family in 15 seconds. Learn the six patterns IBPS rotates (difference, ratio, ×n±k, squares/cubes, double-difference and mixed), the "check the gaps first" habit, and the wrong-term variant, and series becomes a reliable scorer rather than a staring contest.⏱ 18 min read

4Quadratic Equations & InequalitiesThe two-equation "compare x and y" set — 0–5 marks that are pure mechanics. You rarely need the quadratic formula; factor by the sum-product method, find both roots' signs, and apply the comparison rule. Learn the sign shortcut and the "can't compare when ranges overlap" trap, and these are 30-second marks.⏱ 17 min read

5Arithmetic — Percentage, Profit & Loss, InterestThe engine room of bank quant — 5–8 direct marks plus the hidden math inside every caselet and DI set. One toolkit (percentage as a fraction, the multiplying factor, and the SI/CI relationship) powers percentage, profit-loss, discount, interest and partnership alike. Learn the templates once and a whole family of questions collapses into one-liners.⏱ 24 min read

6Ratio, Proportion, Ages & PartnershipThe "shared quantity" family — dividing amounts, comparing values, ages and profit-splits, all on one idea: work with parts, not the total. Learn the single-variable (k) method, the componendo trick for proportions, and the capital×time rule for partnership, and this becomes fast one-line arithmetic that also powers DI and mixtures.⏱ 19 min read

7Average, Mixture & AlligationThe "blend and balance" family — averages, weighted averages, and the alligation cross that solves mixture problems in one line. Learn the total-sum view of averages, the replacement formula, and the alligation see-saw, and a whole class of DI and arithmetic questions collapses into fast mental math.⏱ 18 min read

8Time & Work, Speed & DistanceTwo topics, one engine — rate × time = output. Time & work uses the LCM (total-units) method; speed & distance uses proportionality and relative speed for trains and boats. Learn the LCM trick, the relative-speed rules, and the boats-and-streams formulas, and these become fast, template-driven marks.⏱ 20 min read

9Permutation, Combination & ProbabilityThe counting family — 1–3 Mains marks that hinge on one question: does order matter? Learn the arrangement-vs-selection distinction, the standard selection templates, and probability as favourable ÷ total, and these move from intimidating to formulaic. IBPS keeps them simple; the trap is over-complicating.⏱ 19 min read

10Mensuration — 2D & 3DThe formula-recall topic — areas and perimeters of 2D shapes, and volumes and surface areas of 3D solids. 1–2 marks direct, but the same formulas power many DI and geometry questions. Learn the core formula set, the "which formula does this word ask for" habit, and a few shortcuts, and mensuration becomes fast, certain marks.⏱ 17 min read

11Data Sufficiency (Quant)The numerical cousin of reasoning DS — decide whether the statements give enough to solve, not what the answer is. 3–5 Mains marks that reward judging solvability over grinding out the value. Learn the "count your equations" habit, the fixed option key, and the unique-answer test, and quant DS becomes fast, high-accuracy marks.⏱ 16 min read

12Quantity Comparison (I vs II)The Mains "compute two quantities and compare them" set — Quantity I and Quantity II, pick the relation. It's arithmetic wrapped in a fixed answer key, and the smart move is to simplify or estimate rather than fully compute both. Learn the option framework, the estimate-first habit, and the equal-case rule, and these are quick marks.⏱ 15 min read
