How to Solve RBI Grade B Quantitative Aptitude Questions Quickly

The Quantitative Aptitude section in the RBI Grade B 2025 exam requires speed and accuracy. You do not just need to solve the questions you need to solve them fast. With limited time and tricky calculations, the right approach can make all the difference. Here is how you can tackle this section.

Master the Basics Before Rushing into Speed Tricks

Imagine trying to drive a sports car without knowing how to steer. That is what solving quant questions without strong basics feels like. Make sure you have a solid understanding of key topics like percentages, ratios, averages, profit and loss, time and work and data interpretation. The faster you recognize question types, the quicker you can apply the right technique.

Use Shortcuts

Speed is important in the Quantitative Aptitude section and using shortcuts can help solve questions faster. Instead of doing long multiplications, simple shortcuts can save time. For example, to find 5% of a number, just divide it by 20. Also learning squares, cubes, and fraction-to-decimal conversions up to 30 helps in quick calculations and avoids wasting time on lengthy steps.

Approximate When You Can

Exact calculations are not always necessary. Approximation is a time saver especially in percentage and ratio-based questions. For example, if you need to calculate 48% of 198, rounding it to 50% of 200 gives 100 which is close enough to get the correct answer quickly.

Data Interpretation (DI)

DI questions can be a great way to score marks but they can also take up too much time if not handled smartly. To solve them quickly, start by analyzing the data instead of jumping straight into calculations. Focus only on the important values as many numbers in a table are just distractions. Use mental math to make quick estimates instead of getting stuck in long calculations. This approach helps in solving DI questions faster and more accurately.

Solve Previous Year Papers and Take Mock Tests

Mock tests are not just practice they are a reality check. Simulating exam conditions improves speed, accuracy, and time management and revising previous year papers helps you recognize patterns and frequently asked question types.

Know When to Skip

Some questions are just designed to waste your time. If you find yourself stuck for more than 40–50 seconds, mark it for review and move on. Getting stuck on one question can cost you several easy marks in other questions.
