Question 65

Ram spends 20% of his monthly income on his household expenditure, 15% of the rest on books. 30% of rest on clothes and saves the rest. On counting, he comes to know he has finally saved Rs. 9,520. Find out his monthly income?

Solution

Let the monthly income be $$x$$

money spend on household expenditure=20% of $$x$$

money spend on books=15% of (80% of $$x$$)=12% of $$x$$

money spent on clothes=30% 0f (68% 0f $$x$$)=20.4% of $$x$$

Amount he has saved=[100-(20+12+20.4)]% of $$x$$=47.6% of $$x$$=9520

∴ x=20,000
