Question

A man earns $₹25440$ per month. He spends $\frac{1}{4}$ of it on house rent, $\frac{3}{8}$ on food and clothes, $\frac{1}{10}$ on insurance and $\frac{1}{5}$ on other items. The rest he saves. How much does he save each month?

Answer 1

Total earning in $1$ month $=₹25440$

Money spent on rent is $\frac{1}{4}$ of total earning $=₹\frac{1}{4}\times 25440$

$=₹6360$

Money spent on food is $\frac{3}{8}$ of total earning $=₹\frac{3}{8}\times 25440$

$=₹9540$

Money spent on insurance is $\frac{1}{10}$ of total earning $=₹\frac{1}{10}\times 25440$

$=₹2544$

Money spent on other items is $\frac{1}{5}$ of total earning $=₹\frac{1}{5}\times 25440$

$=₹5088$

Therefore, the total money spent $=₹(6360+9540+2544+5088)$

$=₹23532$

So, money saved by the man $=₹(25440-23532)$

$=\mathbf{₹}\mathbf{}\mathbf{1908}$

Hence, the man saves $\mathbf{₹}\mathbf{}\mathbf{1908}$ each month.
