Adam pays $400 for a TV set at a discount of 20%.
- What is the usual price of the TV set?
- Bryan pays $300 for the same TV set. What is the percentage discount that is given to Bryan?
(a)
Price of the TV with 20% discount
= 100% - 20%
= 80%
80% → $400
1% → 400 ÷ 80 = $5
100% → 100 x 5 = $500
Usual price of the TV set = $500
(b)
Discount that Bryan is given
= 500 - 300
= $200
Percentage discount that is given to Bryan
=
200500 x 100%
= 40%
Answer(s): (a) $500; (b) 40%
