PSLEBen bought one stereo system for $216 after a discount of 10%.
- What was the price of the stereo system before discount?
- He paid $132 for a television set. The total discount for the stereo system and television set was $156. What was the percentage discount given for the television set?
(a)
Price of the stereo system after the discount in percentage
= 100% - 10%
= 90%
90% of the price of the stereo system = 216
1% of the price of the stereo system = 216 ÷ 90 = 2.4
100% of the price of the stereo system = 100 x 2.4 = 240
Price of the stereo system before the discount = $240
(b)
Discount of the stereo system
= 240 - 216
= $24
Discount of the television set
= 156 - 24
= $132
Original price of the television set
= 132 + 132
= $264
Percentage discount of the television set
=
132264 x 100%
= 50%
Answer(s): (a) $240; (b) 50%
