Question

Mrs Rewari spends $25\%$ of her salary on house rent, $30\%$ on the education of her children and $40\%$ on household expenditure. Find her salary if she saves $Rs1470$ per month.

• A. $12300$
• B. $29400$
• C. $43700$
• D. $38200$

Answer 1

The correct option is B $29400$

Let total Salary$=100\%$

Expenditure$=25\%+30\%+40\%=95\%$

She saves $100\%-95\%=5\%$ of her salary.

Let her salary be $x$

$\frac{5x}{100}=1470$

$\Rightarrow x=1470\times \frac{100}{5}=29,400$

$\therefore$her salary is $Rs.29,400$
