SSC CPO - 11 Nov 2022 - Shift 1 • Quantitative Aptitude • Q121

A man spends 65% of his income. His income increases by 20% and his expenditure also increases by 10%. The percentage of increase in his savings is ________.

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. 38.5%

As we know that

Income = Expenditure + Saving

Let Income is 100 units

According to the question

Expenditure = 65 units

Saving = 35 units

Now, Income is 120 units

and Expenditure = 65 × 1.1 units = 71.5 units

Savings = 120 - 71.5 = 48.5 units

The percentage of increase in his savings is = [(48.5 - 35)/35] × 100 = 38.5%
