PSLEHenry bought one laptop for $198 after a discount of 25%.
- What was the price of the laptop before discount?
- He paid $135 for a television set. The total discount for the laptop and television set was $156. What was the percentage discount given for the television set?
(a)
Price of the laptop after the discount in percentage
= 100% - 25%
= 75%
75% of the price of the laptop = 198
1% of the price of the laptop = 198 ÷ 75 = 2.64
100% of the price of the laptop = 100 x 2.64 = 264
Price of the laptop before the discount = $264
(b)
Discount of the laptop
= 264 - 198
= $66
Discount of the television set
= 156 - 66
= $90
Original price of the television set
= 135 + 90
= $225
Percentage discount of the television set
=
90225 x 100%
= 40%
Answer(s): (a) $264; (b) 40%
