Question

The price of a book is increased by 25%. If the new price is * 100 more than the old price, find the old price and the new price. ​

Answer 1

Answer:

Old price = 400 Rs , New price = 500Rs.

Step-by-step explanation:

Old price = x

New price = x+ (x*25)/100

= x + x/4 = 5x/4

Given , $\frac{5x}{4} - x = 100\\=> \frac{x}{4} = 100\\=> x= 400$

so , new price = (5*400)/4 = 500 .
