(2)old price to the new price.

Answer 1

Hi,

Suppose the price of the chair is 100
Then, the decrease in price is 25
New price is 75

Ratio 1
25:100 = 1:4

Ratio 2
100:75 = 4:3

Hope it helps

Answer 2

Consider,

Old Price = Rs. 100, New Price = Rs. 75

Therefore, change in price = Rs. 25.

1) Change in price / Old price = 25/100 = 1/4

2) old price / New Price = 100/75 = 4/3
