Question

A man spends 35% of his income on food, 25% on children's education, and 80% of the remaining on house rent. What percent of his income he is left with?

Answer 1

Given :

Amount spent on food $=35\%$

Amount spent on children's education$=25\%$

Then, the total amount spent $=$amount spent on food $+$ amount spent on children's education

$=35\%+25\%=60\%$

Remaining amount $=40\%$

$80\%$of remaining amount $=\frac{80}{100}\times 40=32\%$

So, the amount left with him $=$ remaining amount $-32\%$ $=40\%-32\%=8\%$

Hence, $8\%$ of his income is left with him.
