PSLETommy bought one printer for $192 after a discount of 20%.
- What was the price of the printer before discount?
- He paid $124 for a projector. The total discount for the printer and projector was $172. What was the percentage discount given for the projector?
(a)
Price of the printer after the discount in percentage
= 100% - 20%
= 80%
80% of the price of the printer = 192
1% of the price of the printer = 192 ÷ 80 = 2.4
100% of the price of the printer = 100 x 2.4 = 240
Price of the printer before the discount = $240
(b)
Discount of the printer
= 240 - 192
= $48
Discount of the projector
= 172 - 48
= $124
Original price of the projector
= 124 + 124
= $248
Percentage discount of the projector
=
124248 x 100%
= 50%
Answer(s): (a) $240; (b) 50%
