PSLEIan bought one television set for $204 after a discount of 20%.
- What was the price of the television set before discount?
- He paid $176 for a stereo system. The total discount for the television set and stereo system was $195. What was the percentage discount given for the stereo system?
(a)
Price of the television set after the discount in percentage
= 100% - 20%
= 80%
80% of the price of the television set = 204
1% of the price of the television set = 204 ÷ 80 = 2.55
100% of the price of the television set = 100 x 2.55 = 255
Price of the television set before the discount = $255
(b)
Discount of the television set
= 255 - 204
= $51
Discount of the stereo system
= 195 - 51
= $144
Original price of the stereo system
= 176 + 144
= $320
Percentage discount of the stereo system
=
144320 x 100%
= 45%
Answer(s): (a) $255; (b) 45%
