PSLEBilly bought one television set for $238 after a discount of 15%.
- What was the price of the television set before discount?
- He paid $180 for a computer. The total discount for the television set and computer was $102. What was the percentage discount given for the computer?
(a)
Price of the television set after the discount in percentage
= 100% - 15%
= 85%
85% of the price of the television set = 238
1% of the price of the television set = 238 ÷ 85 = 2.8
100% of the price of the television set = 100 x 2.8 = 280
Price of the television set before the discount = $280
(b)
Discount of the television set
= 280 - 238
= $42
Discount of the computer
= 102 - 42
= $60
Original price of the computer
= 180 + 60
= $240
Percentage discount of the computer
=
60240 x 100%
= 25%
Answer(s): (a) $280; (b) 25%
