PSLEBryan bought one television set for $172 after a discount of 20%.
- What was the price of the television set before discount?
- He paid $132 for a mobile phone. The total discount for the television set and mobile phone was $175. What was the percentage discount given for the mobile phone?
(a)
Price of the television set after the discount in percentage
= 100% - 20%
= 80%
80% of the price of the television set = 172
1% of the price of the television set = 172 ÷ 80 = 2.15
100% of the price of the television set = 100 x 2.15 = 215
Price of the television set before the discount = $215
(b)
Discount of the television set
= 215 - 172
= $43
Discount of the mobile phone
= 175 - 43
= $132
Original price of the mobile phone
= 132 + 132
= $264
Percentage discount of the mobile phone
=
132264 x 100%
= 50%
Answer(s): (a) $215; (b) 50%
