PSLEElijah bought one mobile phone for $189 after a discount of 30%.
- What was the price of the mobile phone before discount?
- He paid $111 for a tablet. The total discount for the mobile phone and tablet was $155. What was the percentage discount given for the tablet?
(a)
Price of the mobile phone after the discount in percentage
= 100% - 30%
= 70%
70% of the price of the mobile phone = 189
1% of the price of the mobile phone = 189 ÷ 70 = 2.7
100% of the price of the mobile phone = 100 x 2.7 = 270
Price of the mobile phone before the discount = $270
(b)
Discount of the mobile phone
= 270 - 189
= $81
Discount of the tablet
= 155 - 81
= $74
Original price of the tablet
= 111 + 74
= $185
Percentage discount of the tablet
=
74185 x 100%
= 40%
Answer(s): (a) $270; (b) 40%
