Question

The salary of a man has increased by 20%. If he now gets Rs. 3,000, his salary before the increase was

• A. $Rs.2,000$
• B. $Rs.2,300$
• C. $Rs.2,400$
• D. $Rs.2,500$

Answer 1

Answer: (D)

$Rs.2,500$

Let the previous salary be $x$.

It is given that the present salary of the man is Rs.$3,000$ after the increase in salary by $20$%, therefore, we have:

$20$% of $x+x=$Rs.$3000$

$\Rightarrow \frac{20}{100}\times x+x=3000$

$\Rightarrow \frac{x}{5}+x=3000$

$\Rightarrow \frac{x}{5}+\frac{5x}{5}=3000$

$\Rightarrow \frac{x+5x}{5}=3000$

$\Rightarrow 6x=3000\times 5$

$\Rightarrow 6x=15000$

$\Rightarrow x=\frac{15000}{6}$

$\Rightarrow x=2500$

Hence, his salary before the increase was Rs.$2,500$.
