Let the price of the book is 100
So, after increasing 25 % , the price is 100+ 25=125
Now , to reduce the price from 125 to 100 , we have to calculate the % for 25 on 125. Means,
At 125 reduction is 25
At 1 reduction is 25/125
At 100 reduction is 25 *100/125 = 20
Hence, price is to be reduced by 20% [Ans (A)]
