Question

Geetha earns Rs.$12000$ a month, out of which she saves Rs.$3000$. Find the ratio of her expenditure to her income.

Answer 1

Money earned,$E=\text{Rs.}12000$

Money saved, $S=\text{Rs.}3000$

Expenditure, $E_x=E-S$

$=12000-3000$

$=\text{Rs.}9000$

Ratio$=E_x:E$

$=9000:12000$ = $\frac{9000}{12000}$

$=\frac{3\times 3000}{4\times 3000}=\frac{3}{4}=3:4$
