Question

After spending $69\%$ of his monthly earnings a man saves $Rs.2108$. Find his monthly income.

Answer 1

Let the monthly income $=Rs.x$

$=69\%$

Spent $=x\times \left(69/100\right)$

$=0.69x$

saved amount $=x-0.69x=0.31x$

$=\frac{31x}{100}$

It is given that saved amount $=Rs.2108$

So, $\frac{31x}{100}=2108$

$\Rightarrow 31x=2108\times 100$

$\Rightarrow x=\frac{2108\times 100}{31}$

$\Rightarrow x=Rs.6800$

$\therefore$ His monthly income $x=Rs.6800$
