Question

A coolie deposits Rs. 150 per month in his post office Saving Bank account. If this is 15% of his monthly income, find his monthly income.

Answer 1

Let his monthly income =Rs.x

$\therefore$ 15% of x =Rs. 150

$\Rightarrow \frac{15}{100}\times x=150$

$\Rightarrow x=\frac{150\times 100}{15}=Rs.1000$

$\therefore$ His monthly income =Rs.1000
