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:
