CAT 99.94%ile | IIM Bangalore Alum
If you look at the historical papers from CAT 2017 to CAT 2025, one statistical reality stands out: Arithmetic constitutes between 38% and 48% of the entire Quantitative Aptitude section.
For non-engineers, CAT repeaters, and working professionals with limited study hours, mastering arithmetic is the single highest return-on-investment prep strategy available.
In a 22-question 40-minute QA section, solving 8 questions with 100% accuracy yields 24 raw marks. In CAT 2025, 24 raw marks comfortably delivered a 92.8+ percentile in Quant. Arithmetic provides those 8 questions every single year.
| Subtopic | Total PYQs (2017-2025) | Avg Qs Per Slot | Difficulty Rating |
|---|---|---|---|
| Time, Speed & Distance (Races, Trains, Escalators) | 54 | 2.2 | Moderate to High |
| Time & Work (Pipes, Cisterns, Efficiency) | 48 | 1.9 | Easy to Moderate |
| Percentages, Profit & Loss, Discounts | 52 | 2.1 | Easy to Moderate |
| Averages, Mixtures & Alligations | 46 | 1.8 | Moderate |
| Simple & Compound Interest, Installments | 34 | 1.4 | Easy (Formulaic) |
Rather than setting up 4 algebraic equations with x and y, top percentile scorers use ratio transformations and weighted average balancing:
If Efficiency Ratio E1 : E2 = a : b, then Time Taken Ratio T1 : T2 = b : a (when total work is constant).
Use this to eliminate variables when solving men-women-days efficiency problems from CAT 2024 Slot 1.
When two objects travel towards each other or start from the same point, the distance covered is directly proportional to speed for equal time intervals:

Typically 8 to 10 out of 22 questions (around 40% of the entire section) are from Arithmetic.
Yes. Arithmetic (8-10 Qs) and Algebra (6-8 Qs) together comprise over 70% of the QA section. Mastering these two areas is sufficient to score 99+ percentile in QA.
Discuss mock analysis, DILR approaches, and QA shortcuts with 3,400+ aspirants.
We analyzed test-taking datasets across 2,400+ aspirants to determine whether taking 50+ mocks yields higher percentiles or leads to burnout. Here is the mathematical sweet spot.
Why do students leave 3 easy questions unread in the last 2 minutes of a section? The 3-Round ABC attempt strategy guarantees you never leave a free mark on the table.
