IBPS quant guide
IBPS quant: what is on the paper, and how to get fast enough for it
Quantitative Aptitude is 35 questions in IBPS PO prelims (30 marks under the CRP PO XV and current CRP PO XVI, 2026, notifications), and Numerical Ability is another 35 in IBPS Clerk — both inside a 20-minute sectional window, about 34 seconds a question. Very few aspirants lose that section on theory. They lose it on seconds. Simplification, number series, quadratic comparison and data interpretation make up most of the paper. ComputePrep drills simplification, quadratic comparison and data interpretation against a clock (number series is a pattern-recognition topic and is not drilled here) — a free daily set at three difficulties, 15 to 70 seconds a question, with the fast method shown step by step after you answer.
The pattern, stage by stage
Quant changes character between the stages: prelims is a raw arithmetic sprint, while mains replaces most of it with Data Analysis and Interpretation — bigger sets, heavier numbers, and caselets you have to read before you can calculate.
| Paper | Section | Questions | Marks | Time |
|---|---|---|---|---|
| IBPS PO Prelims (CRP PO XVI, 2026) | Quantitative Aptitude | 35 | 30 | 20 min (sectional) |
| IBPS PO Mains (CRP PO XVI) | Data Analysis & Interpretation | 40 | 60 | 45 min |
| IBPS Clerk Prelims (CRP CSA XVI, 2026) | Numerical Ability | 35 | 35 | 20 min (sectional) |
| IBPS Clerk Mains (CRP CSA XVI) | Quantitative Aptitude | 40 | 50 | 35 min |
Question counts and timings are from the latest official notification we have checked; where a cycle changed the pattern, the row names that cycle. Exam boards revise the pattern between cycles — confirm every figure against the current year's notification before you plan around it.
Which topics actually carry the marks
A typical IBPS prelims quant paper is far more predictable than the syllabus makes it look. Roughly, by share of the 35 questions:
- Simplification and approximation. Often 10–15 questions. Pure speed — no concept to learn, only a recall base and shortcuts. Practise free: simplification questions, fast-calculation drills.
- Data interpretation. Usually 10 questions across two sets (table, bar, line, pie or caselet). The maths is easy; the arithmetic volume is not. Practise free: data interpretation sets, caselet DI.
- Number series. About 5 questions — missing-number or wrong-number. Pattern recognition first, arithmetic second. ComputePrep does not drill number series.
- Quadratic equation comparison. About 5 questions in the x-vs-y format. Fast marks once factorising is automatic. Practise free: quadratic equation drills.
- Arithmetic word problems. The remainder: percentages, profit and loss, simple and compound interest, averages, ratio, time and work, speed–distance, boats and streams, mixtures, and a stray permutation or probability question. Practise free: percentages, profit and loss, time and work, speed, time and distance.
What to practise daily
- Ten minutes on the recall base. Tables to 20, squares to 30, cubes to 15, and the fraction–percentage pairs. If you are recomputing 17 × 18 during a paper, no shortcut will save you.
- Three timed drills. ComputePrep serves timed drills daily across 33 drill types — simplification, DI, percentages, interest, time and work, speed–distance and the vedic shortcuts. Against a real deadline, not a stopwatch you glance at.
- Review the method, not the answer. After each question ask "was there a faster route?" rather than "was I right?". Right-but-slow is the actual problem and it is invisible unless you look for it.
- Practise approximation deliberately. In a five-option MCQ you rarely need the exact value — you need enough precision to eliminate four options. This one habit is worth minutes across a paper.
- One topic at a time. Per-topic timing tells you where you are slow. "Time and work costs me 70 seconds" is fixable; "quant is hard" is not.
What ComputePrep covers — and what it does not
ComputePrep drills the calculation layer: timed daily drills across 33 drill types plus the vedic shortcuts that make them fast. It is not a full quant course — it does not teach a chapter you have never seen, it does not cover the descriptive paper, and it will not build the reading skill that mains caselets need. Use it to turn knowledge you already have into speed you do not yet have.

The other section
Reasoning daily (Deduce) is the IBPS reasoning guide from the same makers — seating, syllogism and the rest of the paper, one free daily. Topic guides: seating arrangement, syllogism, clue phrases, how to get faster at seating. Deduce's reasoning puzzle book is the printed companion.
Frequently asked questions
How many quant questions are there in IBPS PO prelims?
35 questions carrying 30 marks, with a 20-minute sectional time limit, under the CRP PO XVI (2026) notification — unchanged from CRP PO XV. IBPS Clerk prelims (CRP CSA XVI) has 35 Numerical Ability questions, for 35 marks, in the same window. Confirm against the notification for your cycle.
Which quant topic carries the most marks in IBPS prelims?
Simplification and approximation, usually 10 to 15 questions, followed by data interpretation at around 10. Between them they are close to two-thirds of the section, and both are decided by calculation speed rather than concept.
How fast do I need to be for the 20-minute sectional?
About 34 seconds per question if you attempt all 35 — which almost nobody does. A realistic target is 25 to 28 solid attempts, which still means roughly 45 seconds each including reading.
Do I need vedic maths for IBPS?
You need five or six shortcuts, not fifty sutras. Nikhilam for multiplying near a base, squaring numbers ending in five, squaring near a base, the same-tens/units-add-to-ten case, and difference of squares cover most of what a prelims paper throws at you.
Is IBPS Clerk quant easier than IBPS PO quant?
The topics overlap almost entirely. Clerk numerical ability leans harder on simplification and straightforward arithmetic and lighter on complex DI, but the sectional clock is identical, so the speed requirement is not lower.
