✔ 最佳答案
The selling price is=320x(1-30%)
=320x70%
=$224
The cost price is
=224/(1-48%)
=224/52%
=430.8(1d.p.)
The profit per cent is
=(430.8-224)/430.8x100%
=206.4/483.8x100%
=48%
我唔知岩唔岩,你最好check下la!!

The discount = 320x30% = $96
The sold price = 320 – 96 = $224
The cost price = 96 / 48% = $200
The profit percent = (224-200)/200 = 12%
The sold price = 320 – 96 = $224
The cost price = 96 / 48% = $200
The profit percent = (224-200)/200 = 12%
