Answer 1

Answer :

Let , salary before increment = x

Given : New salary = Rs 25,000 ( salary after increment )

And

Salary of Mohan is increased by 25% , So

x + 25% = 25000

$$\begin{gathered} \Rightarrow x+\frac{25x}{100}=25000 \\ \Rightarrow x+\frac{x}{4}=25000 \\ \Rightarrow \frac{4x+\hspace{0.17em}x}{4}=25000 \\ \Rightarrow \frac{5\hspace{0.17em}x}{4}=25000 \\ \Rightarrow x=25000\times \frac{4}{5} \\ \Rightarrow x=5000\times 4 \\ \mathbf{\Rightarrow }\mathit{x}\mathbf{}\mathbf{=}\mathbf{}\mathbf{}\mathbf{20000} \end{gathered}$$

And

Salary before increment = Rs . 20000 ( Ans )
