Question

The price of a sweater was slashed from ₹ 960to ₹816 by a shopkeeper in the winter season. Find the rate of discount given by him.

Answer 1

let the discount be x%
therefore

960 - x%of960 = 816
960 - x/100 ÷ 960 = 816
960 - x × 960/100 = 816
960 - x×9.6 = 816
960 = 816 + x×9.6
x×9.6 = 960-816
x×9.6 = 144
x = 144/9.6
x = 15

therefore,

rate of discount given by shopkeeper = 15%
