Adam pays $900 for a TV set at a discount of 10%.
- What is the usual price of the TV set?
- Bryan pays $700 for the same TV set. What is the percentage discount that is given to Bryan?
(a)
Price of the TV with 10% discount
= 100% - 10%
= 90%
90% → $900
1% → 900 ÷ 90 = $10
100% → 100 x 10 = $1000
Usual price of the TV set = $1000
(b)
Discount that Bryan is given
= 1000 - 700
= $300
Percentage discount that is given to Bryan
=
3001000 x 100%
= 30%
Answer(s): (a) $1000; (b) 30%
