** Profit, Loss & Discount **

**Cost price :** The money paid by the shopkeeper to buy the goods from a manufactures or a wholesale is called the cost price of the shopkeeper & it is abbreviated as C.P.

** Selling price : **The price at which a shopkeeper sells the goods is called the selling price of the shopkeeper, it is abbreviated is S.P.

Shopkeeper makes gain or profit if S.P. > C.P.

Profit = S.P. – C. P.

S.P. = Profit + C.P.

C.P. = S.P. – Profit

Loss = C.P. – S.P.

S.P. = C.P. – Loss

C.P. = S.P. + Loss

** Gain or loss is always calculated on C.P.**

**Overhead Charges : **Shopkeeper has to bear some additional expenses such as sales tax, labour charges, maintenance charges for the goods before they are sold. Such charges are called overhead charges. Overhead charges becomes a put of cost price.

** Illustration 12**

An article was purchased for M400 and sold for M336. Find the loss & loss percent.

** Solution**

C.P. of article = M400

S.P. of article = M336

Since S.P. < C.P., so there is a loss

Loss = C.P. – S.P.

= M(400 – 336) = M64

Hence, loss = M64

Loss % = 16%.
