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
