Question

How to find the cost price when there is a loss or profit?
EG:- (a). When there is a loss of 4%
(b). When a profit of 8%

Answer 1

• Gain % = (Gain / CP) * 100
• Loss % = (Loss / CP) * 100
• SP = [(100 + Gain%) / 100] * CP
• SP = [(100 – Loss %) / 100]*CP

The above two formulas can be stated as,

If an article is sold at a gain of 8%, then SP = 108% of CP.

If an article is sold at a loss of 4%, then SP = 96% of CP.

• CP = [100 / (100 + Gain%)] * SP
• CP = [100 / (100 – Loss%)] * SP

let cp be cost price
let sp be selling price
