Inside Quantitative Aptitude

ICAI Study Material · May 2026 edition

Part A — Business Mathematics

  1. Ratio and Proportion, Indices, LogarithmsFoundation of all maths chapters — log rules and index laws appear embedded in later chapters too.
  2. EquationsLinear, quadratic, simultaneous — high marks, formula-driven, straightforward to score once you know the types.
  3. Linear InequalitiesSolve and graph inequalities — brief chapter but a clean 4–6 marks if you remember the sign-flip rule for negatives.
  4. Mathematics of FinanceInterest, annuities, EMIs — the heaviest-weighted maths chapter, attempt after attempt.
  5. Basic Concepts of Permutations and CombinationsnPr, nCr, and counting problems — most students drop marks here; one correct formula chain = full marks.
  6. Sequence and Series — Arithmetic and Geometric ProgressionsAP and GP sums and nth-term formulas — predictable question types, high scoring with practice.
  7. Sets, Relations and Functions, Basics of Limits and Continuity FunctionsSet operations, Venn diagrams, domain-range — the conceptual bridge to calculus; Venn problems are quick marks.
  8. Basic Applications of Differential and Integral Calculus in Business and EconomicsDifferentiation for cost/revenue optima and basic integration — business-applied, not pure maths; manageable.

Part B — Logical Reasoning

  1. Number Series, Coding and Decoding and Odd Man OutPattern recognition questions — LR's easiest sub-topic; 3–5 marks available without formula-work.
  2. Direction Sense TestNavigate north/south/east/west distance problems — fully visual once you draw the path; no student should drop these marks.
  3. Seating ArrangementsLinear and circular arrangements — can get complex fast; draw the table, rule out, it becomes mechanical.
  4. Blood RelationsFamily-tree deduction questions — short but confusing if you skip drawing the tree; safe 3–4 marks with care.

Part C — Statistics

  1. Statistical Description of Data and SamplingTypes of data, frequency tables, diagrams — a lot of definitions; tested lightly but can't be skipped entirely.
  2. Measures of Central Tendency and DispersionMean, median, mode, SD, variance — computation-heavy and consistently 10–12 marks every paper; practise every formula.
  3. ProbabilityClassical probability and addition/multiplication theorems — moderate difficulty, 6–8 marks, and the base for Theoretical Distributions.
  4. Theoretical DistributionsBinomial and Poisson distributions — formula application chapter; straightforward once you identify which distribution to use.
  5. Correlation and RegressionKarl Pearson's r and regression lines — students fear this but the computation follows a fixed table format every time.
  6. Index NumbersLaspeyre's, Paasche's, Fisher's index — a lot of formulas in one chapter; highest confusion-to-marks ratio in the stats section.

How it works here

Question → your attempt → marks per step

You answer first. Then the solution opens step by step, with the marks each step carries — so you see exactly where answers gain and lose marks in the real exam.
