Question

7. The salary of an employee is increased by 20%. By what percentage should the new salary be reduse
to restore the original salary?
​

Answer 1

Taking the sample value to be 100.

A 20% increase means 100*1.2=120.

Thus a total increase of 20.

Now let's find the ratio of 20 to 120 i.e., 20/120=0.1666.

Changing to percentage 0.1666*100=16.6%.

Hence, a decrease of 16.6% to the new salary will restore the original salary.

Hope this helps!
