PSLEDaniel bought one hard drive for $192 after a discount of 20%.
- What was the price of the hard drive before discount?
- He paid $143 for a laptop. The total discount for the hard drive and laptop was $165. What was the percentage discount given for the laptop?
(a)
Price of the hard drive after the discount in percentage
= 100% - 20%
= 80%
80% of the price of the hard drive = 192
1% of the price of the hard drive = 192 ÷ 80 = 2.4
100% of the price of the hard drive = 100 x 2.4 = 240
Price of the hard drive before the discount = $240
(b)
Discount of the hard drive
= 240 - 192
= $48
Discount of the laptop
= 165 - 48
= $117
Original price of the laptop
= 143 + 117
= $260
Percentage discount of the laptop
=
117260 x 100%
= 45%
Answer(s): (a) $240; (b) 45%
