Question

The ratio of expenditure to the income of a person is 7 : 8. What amount will he save for month if his monthly salary is Rs. 64,000?

Answer 1

Let the expenditure and income be $7x$ and $8x$ respectively.

Monthly salary $=Rs.64000\left(\text{Given}\right)$

$8x=64000$

$=\frac{64000}{8}=8000$

Expenditure $=7x=7\times 8000=56000$

Therefore,

Saving $=$ Income $-$ Expenditure

Saving $=64000-56000=Rs.8000$

Hence the saving of the person $Rs.8000$.
