Question

the salary of an officer is increased by 20% by what percentage should the new salary be reduced to restore the original salary

Answer 1

Answer:

Let consider an amt =100

A/Q

100+100 of 20% = 100 + 20

120 of x% = 100

6x / 5 =100

x = 83.33

Reduced % = 100 - 83.33

= 16.67%

Step-by-step explanation:

Answer 2

Answer:

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.
