PSLEDavid bought one laptop for $171 after a discount of 25%.
- What was the price of the laptop before discount?
- He paid $186 for a television set. The total discount for the laptop and television set was $171. What was the percentage discount given for the television set?
(a)
Price of the laptop after the discount in percentage
= 100% - 25%
= 75%
75% of the price of the laptop = 171
1% of the price of the laptop = 171 ÷ 75 = 2.28
100% of the price of the laptop = 100 x 2.28 = 228
Price of the laptop before the discount = $228
(b)
Discount of the laptop
= 228 - 171
= $57
Discount of the television set
= 171 - 57
= $114
Original price of the television set
= 186 + 114
= $300
Percentage discount of the television set
=
114300 x 100%
= 38%
Answer(s): (a) $228; (b) 38%
