Question

A man got a $10$% increase in his salary. If his new salary is $Rs.1,54,000$, find his original salary.

Answer 1

Let the man salary before increment $=x$

There is $10$% increase in salary $=x+\left(\frac{10}{100}\right)x$

$=x+0.1x=1.1x$

Increased salary $=154000$

Therefore $1.1x=154000$

$=\frac{154000}{1.1}=1,40,000$

$\therefore$ the original salary is $1,40,000$
