Explanation:-

Correct Question: the salary of an officer is increased by 30%. what percentage should the new salary be reduce to restore the original salary

Approach:

I used here a simple formula

$\frac{r}{100 + r} \times 100$

here, r is the number given increased or decreasd.

Given:

increased percentage => 30%

Solution:

so, put the value

$\frac{30}{100 + 30} \times 100$

=>

$\frac{30}{130} \times 100$

=> 23.07% is the required answer.
