PSLEAsher bought one computer for $175 after a discount of 30%.
- What was the price of the computer before discount?
- He paid $170 for a television set. The total discount for the computer and television set was $155. What was the percentage discount given for the television set?
(a)
Price of the computer after the discount in percentage
= 100% - 30%
= 70%
70% of the price of the computer = 175
1% of the price of the computer = 175 ÷ 70 = 2.5
100% of the price of the computer = 100 x 2.5 = 250
Price of the computer before the discount = $250
(b)
Discount of the computer
= 250 - 175
= $75
Discount of the television set
= 155 - 75
= $80
Original price of the television set
= 170 + 80
= $250
Percentage discount of the television set
=
80250 x 100%
= 32%
Answer(s): (a) $250; (b) 32%
