Question

The salary of an employee was increased by $7\%$ if his present salary is $Rs.9630,$ find his salary before increment.

Answer 1

Given,

Present salary $=$Rs. $9630$

The salary was increased by $7\%$

Let the salary before increment be $x$.

$\therefore$ Increase in the present salary$=7\%ofx=\frac{7x}{100}$

According to question,

$x+\frac{7x}{100}=9630$

$\Rightarrow \frac{7x+100x}{100}=9630$

$\Rightarrow \frac{107x}{100}=9630$

$\Rightarrow 107x=9630\times 100$

$\Rightarrow 107x=963000$

$\Rightarrow x=\frac{963000}{107}$

$\Rightarrow x=9000$

Therefore, the salary of the employee before increment was Rs. $9000$
