Question

The ratio of income to savings of a family $11:2$ find the expenditure if the saving is $Rs.1520$.

Answer 1

Ratio of income and saving $=11:2$

So let the income be $11x$, then the saving will be $2x$

Total income $=$ expenditure $+$ saving
And the saving is given as $Rs.1520$

$\Rightarrow 2x=Rs.1520$

$\Rightarrow x=\frac{Rs.1520}{2}$

$\Rightarrow x=Rs.760$
$\Rightarrow$ Income $=11x=11\times Rs.760=Rs.8360$

Expenditure $=$ Income $-$ saving

$=Rs.8360-Rs.1520$

$=Rs.6840$
Therefore, the expenditure of the family is $Rs.6840$.
