PROFIT AND LOSS



PROFIT AND LOSS 



SOME BASIC FORMULA E

1) Gain on Rs. 100 is Gain per cent


2) Loss on Rs. 100 is Loss per cent

 

Example:  The cost price of a shirt is Rs. 200 and  selling price is Rs. 250. Calculate the  % profit.

Solution :  We have, C.P.= Rs. 200, 
                                S.P = Rs. 250.    
                   Profit = S.P. - C.P.
                                250 - 200 = Rs. 50.
                   
               
               

Example: Anu bought a necklace for Rs. 750 and sold it for Rs. 675. Find her percentage loss.

Solution : Here. C.P. = Rs. 750.
                         S.P. = Rs. 675.
                          Loss = C.P. - S.P. = 750 - 675 = Rs. 75.

                     
                    

3) When the selling price and gain% are given:


4) When the selling price and loss% are given:



5) When the cost and gain per cent are given:


6) When the cost and loss %  are given:


Example: Mr. Sharma buys a cooler for Rs. 4500. for how much should he sell so that there is a gain of 8%?

Solution: We have, C.P. = Rs. 4500,  gain% = 8%.

 


          

              =   4860

Example: By selling a fridge for Rs. 7200, Pankaj loses 10%. find the cost price of the fridge.

Solution: We have. S.P. = Rs. 7200, loss% = 10%.
