## How to Calculate Profit and Loss (Page 1/4)

__Important Tips__
(1) Profit and Loss are the difference between cost /purchase price and the selling price

'__XX (Profit Loss) = Selling Price (S.P.) - Cost Price (C.P.)__ ;

if XX is +ve then it's Profit and if XX is -ve it's Loss

(2) Profit Loss % are always expressed in terms of C.P.

Profit % = (S.P. - C.P.)*100 / C.P.

Loss % = (C.P. - S.P.)*100 / C.P.

Question - Type 1 - Ram purchase 100 mango for Rs 75 and sold for Rs 125. What is his loss or profit and what %.

Answer - 1- Sine he has sold for more than the C.P. therefore he has earned a profit.

profit = S.P. - C.P.

= 125 - 75

= Rs 50 is profit

Profit % = (profit)*100 / C.P.

= 50*100 / 75 = 66.67 %

Question - Type 2 - Ram purchase 100 mango for Rs 175 and sold for Rs 125. What is his loss or profit and what %.

Answer - 2- Sine he has sold for less than the C.P. therefore he has earned a loss.

profit = C.P. - S.P.

= 175 - 125

= Rs 50 is Loss

Profit % = (Loss)*100 / C.P.

= 50*100 / 75 = 66.67 %
