Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. 0%

The monthly income of a person was 40,000. He used to save 25% of his income.

monthly income of a person initially = 40000

monthly savings of a person initially = 25% of 40000

= 25/100 × 40000

= 10000

monthly expenditure of a person initially = 40000 -10000

= 30000

His nominal income increases by 15% and his nominal expenditure increases by 20%.

monthly income of a person after increase = 40000 of (100 + 15)%

= 40000 of 115%

= 40000 × 115/100

= 46000

monthly expenditure of a person after increase = 30000 of (100 + 20)%

= 30000 of 120%

= 36000

monthly savings of a person after increase = 46000 - 36000

= 10000

Here the monthly savings of a person initially and after the increase in income is the same.

So the percentage change will be zero.

Percentage change in his nominal savings - (10000 - 10000/10000) × 100

= 0/10000 ×100

= 0
