In April, the profit of a book store is increased by 25%, and in May, it is decreased by 20%. How did the profit of the store at the end of May compare to that in the beginning of April?

Correct option is C

Given:

Profit increased by 25% in April

Then decreased by 20% in May

We are to find the overall net percentage change in profit from the beginning of April to the end of May.

Solution:

Let the initial profit = 100

After 25% increase in April:

100+25% of 100=100+25=125

After 20% decrease in May:

125−20% of 125=125−25=100

So, final profit = ₹100

Final profit is same as initial.
There is no net change in the profit.

Alternate Method:

a + b + $$\frac {ab}{100}$$​​

25 - 20 - $$\frac{500}{100}$$

= 25 - 20 -5

= 25 - 25 = 0

Final profit is same as initial.

There is no net change in the profit.
