A man received $10\%$ increase in his salary. His new salary is $Rs.5060.$ His original salary was

• A. $Rs.4554$
• B. $Rs.4600$
• C. $Rs.4200$
• D. $Rs.4400$

Answer 1

The correct option is B $Rs.4600$

Let original salary be $x$

Increase in salary $10\%$ of $Rsx$

$\begin{array}{c}=Rs\frac{10}{100}x=Rs\frac{x}{10}\\ Newsalary=Rsx+Rs\frac{x}{10}=Rs\frac{11}{10}x\\ Rs\frac{11}{10}x=Rs5060\\ x=Rs\frac{5060\times 10}{11}=Rs4600\\ Thus,theoriginalsalary=Rs4600\end{array}$

Hence,

option $B$ is correct answer.
