✔ 最佳答案
(120 - cost)/cost = 60% = 0.6120 - cost = 0.6cost
cost = 75
selling price = 120( 1- 20%) = 96
percentage profit = (96 - 75)/75*100% = 28%

Profit %=[(Marked price - cost price) / cost price] x 100%
60% = [(120-cost price)/cost price] x 100%
cost price = $75
Discount % = [(Original total price - selling paid) / original total price] x 100%
20% = [(120 - selling price)/120] x 100%
selling price = $96
profit= selling price - cost price = 96 - 75 =$21
60% = [(120-cost price)/cost price] x 100%
cost price = $75
Discount % = [(Original total price - selling paid) / original total price] x 100%
20% = [(120 - selling price)/120] x 100%
selling price = $96
profit= selling price - cost price = 96 - 75 =$21

Let the cost be $x
(120-x)/x = 60%
120-x = (60%) x
x (1+60%) = 120
x = 120/1.6 = $75
Now it is sold at $120 (1-20%) = $120 (80%) = $96
Profit = $96 - $75 = $21

(Percentage Profit = 21/75 = 28%)
(120-x)/x = 60%
120-x = (60%) x
x (1+60%) = 120
x = 120/1.6 = $75
Now it is sold at $120 (1-20%) = $120 (80%) = $96
Profit = $96 - $75 = $21
