PSLEJustin bought one hard drive for $175 after a discount of 30%.
- What was the price of the hard drive before discount?
- He paid $196 for a tablet. The total discount for the hard drive and tablet was $124. What was the percentage discount given for the tablet?
(a)
Price of the hard drive after the discount in percentage
= 100% - 30%
= 70%
70% of the price of the hard drive = 175
1% of the price of the hard drive = 175 ÷ 70 = 2.5
100% of the price of the hard drive = 100 x 2.5 = 250
Price of the hard drive before the discount = $250
(b)
Discount of the hard drive
= 250 - 175
= $75
Discount of the tablet
= 124 - 75
= $49
Original price of the tablet
= 196 + 49
= $245
Percentage discount of the tablet
=
49245 x 100%
= 20%
Answer(s): (a) $250; (b) 20%
