PSLEPeter bought one massage chair for $224 after a discount of 30%.
- What was the price of the massage chair before discount?
- He paid $132 for a mobile phone. The total discount for the massage chair and mobile phone was $140. What was the percentage discount given for the mobile phone?
(a)
Price of the massage chair after the discount in percentage
= 100% - 30%
= 70%
70% of the price of the massage chair = 224
1% of the price of the massage chair = 224 ÷ 70 = 3.2
100% of the price of the massage chair = 100 x 3.2 = 320
Price of the massage chair before the discount = $320
(b)
Discount of the massage chair
= 320 - 224
= $96
Discount of the mobile phone
= 140 - 96
= $44
Original price of the mobile phone
= 132 + 44
= $176
Percentage discount of the mobile phone
=
44176 x 100%
= 25%
Answer(s): (a) $320; (b) 25%
