PSLEOwen bought one mobile phone for $156 after a discount of 20%.
- What was the price of the mobile phone before discount?
- He paid $118 for a massage chair. The total discount for the mobile phone and massage chair was $157. What was the percentage discount given for the massage chair?
(a)
Price of the mobile phone after the discount in percentage
= 100% - 20%
= 80%
80% of the price of the mobile phone = 156
1% of the price of the mobile phone = 156 ÷ 80 = 1.95
100% of the price of the mobile phone = 100 x 1.95 = 195
Price of the mobile phone before the discount = $195
(b)
Discount of the mobile phone
= 195 - 156
= $39
Discount of the massage chair
= 157 - 39
= $118
Original price of the massage chair
= 118 + 118
= $236
Percentage discount of the massage chair
=
118236 x 100%
= 50%
Answer(s): (a) $195; (b) 50%
