You only need to round off the numbers and do quick calculations.

For example:
19.98% of 749.99 becomes 20% of 750, which is much easier to solve.

Tips to Solve Approximation Questions

This topic carries 5-10 marks in the IBPS Clerk 2025, so you can’t skip this type of question. Here are some tips to help you easily solve approximations.

Round off smartly
Change 749.99 to 750, 19.98% to 20%, 124.99 to 125 — it saves time and helps you calculate faster.

Use basic percentage tricks
Know that:
10% of X = X/10
20% of X = 2 × (X/10)
50% of X = X/2
These tricks save you from lengthy calculations.

Ignore .98 or .99 in exams
If a number is like 499.98, treat it as 500. Don’t waste time dealing with .02 or .01 differences — they don’t change the answer much.

Don’t try to find the exact answer
Remember: You only need the closest match to the actual answer. Look at the options — choose the nearest one.
Practice regularly
The more you practice, the faster you’ll get at rounding, calculating, and spotting correct options without full calculations.
