Question

if a sallery of an officer incresed by 20 percent by what percent should the new sallery refused to restore original sallery​

Answer 1

Hii MATe ☺☺

Let's consider the salary of the officer =100

So, if the salary is increased by 25% then new salary =100+

100

25

×100

=100+25

=125

So, his new salary is 125

To make his salary original 25 must be subtracted from 123, then his salary will be 100 or original salary

So,

% decrease =

125

25 =51 ×100

Answer 2

Answer:

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

Step-by-step explanation:

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.
