Numerical Ability for SBI Clerk

Officially 'Quantitative Aptitude' at Mains — same narrow 6-topic syllabus as IBPS Clerk.

📊 Prelims: 35 Q / 35 marks · Mains (Quantitative Aptitude): 50 Q / 50 marks

How toppers play this section

Identical scope to IBPS Clerk's clerk-level Numerical Ability — 6 topics, no ratio/partnership, average/mixture, permutation-combination or mensuration at this level. Simplification & Approximation is the heaviest, fastest-to-master topic; Data Interpretation and Arithmetic Word Problems (percentage, profit & loss, interest) follow closely. Number Series, Quadratic Equations and Time-Speed-Distance-Work complete a syllabus that rewards drilled speed over broad coverage — 50 questions in 45 minutes leaves little room for slow, first-principles working.

Chapters

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

1Simplification & ApproximationThe heaviest single topic in clerk-level Numerical Ability — exact BODMAS evaluation for simplification questions, and fast, deliberate rounding for approximation questions, each demanding a different discipline despite looking similar.⏱ 5 min read

2Data InterpretationClerk-level DI stays to a single table, bar or line chart with straightforward percentage, ratio and average questions — no caselets, no missing-value puzzles, no data sufficiency layered on top, unlike the PO-level version of this topic.⏱ 5 min read

3Arithmetic — Percentage, Profit & Loss, InterestThe percentage engine that drives profit-loss, discount and interest questions alike — the same core relationship applied to buying-and-selling, marked-price discounting, and money growing over time.⏱ 6 min read

4Number Series — Missing & Wrong TermFind the pattern, not the answer directly — missing-term series ask for the next value once a rule is identified, wrong-term series ask which single value breaks an otherwise-consistent rule.⏱ 6 min read

5Quadratic EquationsSolve two quadratic equations, find both roots of each, and compare the two variables — banking exams package this as a distinctive 'Quantity I vs Quantity II' format rarely seen outside this exam family.⏱ 6 min read

6Time, Speed, Distance & WorkRelative speed for crossing and overtaking, upstream/downstream boat problems, and combined work rates — one core relationship (distance = speed × time, or work = rate × time) applied across every variant.⏱ 8 min read
