PSLEWesley bought one hard drive for $252 after a discount of 20%.
- What was the price of the hard drive before discount?
- He paid $189 for a mobile phone. The total discount for the hard drive and mobile phone was $126. What was the percentage discount given for the mobile phone?
(a)
Price of the hard drive after the discount in percentage
= 100% - 20%
= 80%
80% of the price of the hard drive = 252
1% of the price of the hard drive = 252 ÷ 80 = 3.15
100% of the price of the hard drive = 100 x 3.15 = 315
Price of the hard drive before the discount = $315
(b)
Discount of the hard drive
= 315 - 252
= $63
Discount of the mobile phone
= 126 - 63
= $63
Original price of the mobile phone
= 189 + 63
= $252
Percentage discount of the mobile phone
=
63252 x 100%
= 25%
Answer(s): (a) $315; (b) 25%
