PSLETom bought one television set for $238 after a discount of 30%.
- What was the price of the television set before discount?
- He paid $105 for a laptop. The total discount for the television set and laptop was $147. What was the percentage discount given for the laptop?
(a)
Price of the television set after the discount in percentage
= 100% - 30%
= 70%
70% of the price of the television set = 238
1% of the price of the television set = 238 ÷ 70 = 3.4
100% of the price of the television set = 100 x 3.4 = 340
Price of the television set before the discount = $340
(b)
Discount of the television set
= 340 - 238
= $102
Discount of the laptop
= 147 - 102
= $45
Original price of the laptop
= 105 + 45
= $150
Percentage discount of the laptop
=
45150 x 100%
= 30%
Answer(s): (a) $340; (b) 30%
