Question

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

Answer 1

Let the original salary be x.
So, the new salary after 10% increment is $x[1+(\frac{10}{100}\left)\right]$
= $1.1x$
Now, according to the problem,
$1.1x=₹1,54,000$
$\Rightarrow x=\frac{₹1,54,000}{1.1}\Rightarrow x=₹1,40,000$
So, his original salary is ₹1,40,000
