Question

Ram spends $30\%$ of his salary on house rent, $30\%$ of the rest he spends on his children's education and $24\%$ of the total salary he spends on clothes. After his expenditure, he is left with $\text{Rs.}2500.$ What is Ram's salary?

• A. $\text{Rs.}12000$
• B. $\text{Rs.}20000$
• C. $\text{Rs.}10000$
• D. $\text{Rs.}15000$

Answer 1

The correct option is C $\text{Rs.}10000$

Let Ram's salary be $x.$
Amount spent on rent $=30\%\text{of}x=\frac{30x}{100}$
Amount spent on education
$=30\%$ from rest of the salary
$=\frac{30\times 70x}{100\times 100}=\frac{21x}{100}$
Amount spent on clothes $=24\%$ of total salary $=\frac{24x}{100}$
and saving $=\text{Rs.}2500$

Now, $\frac{30x}{100}+\frac{21x}{100}+\frac{24x}{100}+2500=x$
$\Rightarrow \frac{75x}{100}+2500=x$
$\Rightarrow x=10000$
Hence, Ram's salary is $\text{Rs.}10000.$
