CAT Quantitative Aptitude Formulas Cheatsheet & High-Yield Traps
Comprehensive mathematical formula repository covering Arithmetic, Algebra, Geometry, Number Systems & Modern Math. Master 80+ verified shortcut equations, remainder theorems, and CAT traps.
Executive Briefing & Key Takeaway
Verified SummaryQuantitative Aptitude in CAT consists of 22 questions covering 5 broad modules: Arithmetic (8–9 Qs), Algebra (6–7 Qs), Geometry & Mensuration (3–4 Qs), Modern Math (1–2 Qs), and Number Systems (1–2 Qs). Mastering core formulas in Time Speed Distance (Relative Speed, Harmonic Mean), Time & Work (Efficiency Ratios), Logarithms (Change of Base), Quadratics (Roots Relations, Discriminant), and Triangles (Cosine Rule, Apollonius Theorem) provides a 40+ raw score baseline necessary for 99+ percentile.

ThinkCAT HubFrequently Asked Questions
What are the most important formulas for CAT Quantitative Aptitude?
High-frequency formulas include Harmonic Mean in TSD (2ab/(a+b)), Work-Efficiency inverses, Logarithm base changes, Sum of roots (-b/a) and product (c/a), and Apollonius Theorem (AB² + AC² = 2(AD² + BD²)).
Can I score 99 percentile in CAT QA by just memorizing formulas?
No. CAT questions test conceptual application and boundary conditions rather than direct formula plugging. Formulas serve as speed accelerants once problem representation is understood.
Which chapters have the highest weightage in CAT Quant?
Arithmetic (Percentages, Profit & Loss, TSD, Time & Work) and Algebra (Linear, Quadratics, Logarithms, Functions) collectively make up 75% of the section.
