Quantitative Aptitude is often considered the decisive section in bank examinations like SBI PO, IBPS PO, IBPS Clerk, and RBI Grade B. With strict sectional timing (20 minutes in Prelims for 35 questions), clearing cutoffs and maximizing score requires combining fast mental calculations with strategic question selection.
1. Build High-Speed Calculation Skills
Before tackling complex word problems, eliminate calculation bottlenecks by memorizing fundamental tables and shortcuts:
- Memorize multiplication tables up to 30, squares up to 50, and cubes up to 20.
- Master fraction-to-percentage conversions (e.g., 1/7 = 14.28%, 1/8 = 12.5%).
- Practice mental math techniques for Vedic addition, subtraction, and approximation daily for 15 minutes.
2. High-Yield Topics for Bank Prelims
In Prelims exams, speed-focused topics account for 15 to 20 out of 35 questions. Target these first during your exam attempt:
- Simplification / Approximation: 5–10 questions. Requires basic BODMAS application and percentage shortcuts.
- Quadratic Equations: 5 questions. Learn sign-conversion tricks to solve equations within 2 minutes.
- Number Series: 5 questions (Missing or Wrong Number Series patterns).
- Data Interpretation (DI): 10–15 questions (Bar graphs, Pie charts, Table DI, Line graphs). Focus on average, ratio, and percentage-based calculations.
3. Tackling Mains-Level Caselets & Arithmetic
Bank Mains examinations focus heavily on Caselet DI and Arithmetic-based Data Interpretation. Develop deep conceptual clarity in core topics such as Percentages, Profit & Loss, Ratio & Proportion, Partnership, Simple & Compound Interest, Time & Work, and Boats & Streams. Avoid relying on tricks; understand concepts from the ground up.
4. Mock Test Execution Strategy
During sectional mock tests, divide your 20-minute Prelims window into two phases: spend the first 8–10 minutes solving Speed Math (Simplification, Series, Quadratic) and straightforward DI sets, then spend the remaining 10 minutes on arithmetic questions and remaining DI sets.
