PSLEJapheth bought one printer for $248 after a discount of 20%.
- What was the price of the printer before discount?
- He paid $133 for a stereo system. The total discount for the printer and stereo system was $195. What was the percentage discount given for the stereo system?
(a)
Price of the printer after the discount in percentage
= 100% - 20%
= 80%
80% of the price of the printer = 248
1% of the price of the printer = 248 ÷ 80 = 3.1
100% of the price of the printer = 100 x 3.1 = 310
Price of the printer before the discount = $310
(b)
Discount of the printer
= 310 - 248
= $62
Discount of the stereo system
= 195 - 62
= $133
Original price of the stereo system
= 133 + 133
= $266
Percentage discount of the stereo system
=
133266 x 100%
= 50%
Answer(s): (a) $310; (b) 50%
