PSLEWarren bought one projector for $176 after a discount of 20%.
- What was the price of the projector before discount?
- He paid $138 for a television set. The total discount for the projector and television set was $182. What was the percentage discount given for the television set?
(a)
Price of the projector after the discount in percentage
= 100% - 20%
= 80%
80% of the price of the projector = 176
1% of the price of the projector = 176 ÷ 80 = 2.2
100% of the price of the projector = 100 x 2.2 = 220
Price of the projector before the discount = $220
(b)
Discount of the projector
= 220 - 176
= $44
Discount of the television set
= 182 - 44
= $138
Original price of the television set
= 138 + 138
= $276
Percentage discount of the television set
=
138276 x 100%
= 50%
Answer(s): (a) $220; (b) 50%
