Question

in a sale, Richard bought a TV for £300. The original price of the TV was £380. What was the percentage discount on the TV?

Answer 1

cost price =300
original price =380
profit = 380-300=80
80/380X100=25%

Answer 2

(totalPrice-discountedPrice)/totalPrice x 100
so that would be:

(380-300)/380 x100 = 21%
