Ravi initially used to save 20% of his monthly income. Recently his monthly income was raised by 25%. His nominal savings also went up by 5%. What percentage of his present nominal income does Ravi currently save?

Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. 16.8%.

Let the initial income of Ravi be Rs. 100.

The initial savings of Ravi = 20% of 100

⇒ 20100×100{20 \over 100} \times 100 = Rs. 20

The monthly income is increases by 25%, New income = Rs. 125

Savings are increased by 5%, New savings = 105% of 20

⇒ 105100×20{105 \over 100} \times 20 = Rs. 21

The required percentage = 21125×100{21 \over 125} \times 100

⇒ 84584 \over 5 = 16.8%

Hence Ravi saves 16.8% of his income.
