Question

The price of a book is reduced by 25%, what is the ratio of change in present price to the old price?

Answer 1

Answer:

Answer. Therefore, change in price = Rs. 25.

Answer 2

Answer:

let the original price of book = x

and the reduced price of book =x - 25% of x

Now,

= original price/reduced price

= x/x-25% of x

= x/x-x/4

= 4/3

Hence 4:3 is the ratio of change in present price to the old price.
