Percentage and yearly income

by Dikshya Sharma
(Kathmandu , nepal)

A man spends 20% of his income in food, 15% in clothes, 15% in house rent and 30% in miscellaneous. Find his yearly income if he saves Rs 2500 per months.


Solution

20% + 15% + 15% + 30% = 80%

The man spent 80% of his income.

20% of his income went to saving

Let x be his monthly income

20% of x = Rs 2500

0.2x = Rs 2500

Multiply both sides by 10

0.2x times 10 = Rs 2500 times 10

2x = Rs 25000

Divide both sides by 2

2x/2 = 25000/2

x = Rs 12500

Multiply Rs 12500 by 12 to get his yearly income

12500 x 12 = 150000

The man's yearly income is Rs 150,000
