Selling Price (SP) : The price at which the shopkeeper sells the goods is called the selling price (SP) of the goods sold by the shopkeeper.
Profit : If the selling price of an article is more than its cost price, then the dealer (or shopkeeper) makes a profit (or gain)

3.S.P=[100+Gain %100×C.P] = [100-Loss%100×C.P]
4. C.P=[100100+Gain %×S.P] = [100100-Loss %×S.P]
5. If an article is sold at a gain of say 35%, then SP = 135% of CP
6. If an article is sold at a loss of say 35%, then SP = 65% of CP
