PSLEJustin bought one computer for $180 after a discount of 25%.
- What was the price of the computer before discount?
- He paid $174 for a laptop. The total discount for the computer and laptop was $118. What was the percentage discount given for the laptop?
(a)
Price of the computer after the discount in percentage
= 100% - 25%
= 75%
75% of the price of the computer = 180
1% of the price of the computer = 180 ÷ 75 = 2.4
100% of the price of the computer = 100 x 2.4 = 240
Price of the computer before the discount = $240
(b)
Discount of the computer
= 240 - 180
= $60
Discount of the laptop
= 118 - 60
= $58
Original price of the laptop
= 174 + 58
= $232
Percentage discount of the laptop
=
58232 x 100%
= 25%
Answer(s): (a) $240; (b) 25%
