PSLEJohn bought one hi-fi system for $225 after a discount of 25%.
- What was the price of the hi-fi system before discount?
- He paid $176 for a hard drive. The total discount for the hi-fi system and hard drive was $119. What was the percentage discount given for the hard drive?
(a)
Price of the hi-fi system after the discount in percentage
= 100% - 25%
= 75%
75% of the price of the hi-fi system = 225
1% of the price of the hi-fi system = 225 ÷ 75 = 3
100% of the price of the hi-fi system = 100 x 3 = 300
Price of the hi-fi system before the discount = $300
(b)
Discount of the hi-fi system
= 300 - 225
= $75
Discount of the hard drive
= 119 - 75
= $44
Original price of the hard drive
= 176 + 44
= $220
Percentage discount of the hard drive
=
44220 x 100%
= 20%
Answer(s): (a) $300; (b) 20%
