Profit and Loss

Cost Price (C.P.) The price at which an article is purchased or manufactured is called its cost price. Selling Price (S.P.) The price at which an article is sold, is called its selling price. Profit If the selling price of an article is greater than its cost price, we say that there is a profit or gain. Profit = Selling Price - Cost Price When S.P.>C.P. Profit = S.P. - C.P. S.P.= C.P.+Profit C.P.=S.P.-Profit Profit % = Profit/C.P. * 100 Profit = Profit % * C.P. When C.P.  and Profit% are given then, S.P. = C.P. * ((100+Profit %)/100) When S.P. and Profit % are given then C.P.= 100* S.P./100+ Profit % Loss If the selling price of an article is less than tits cost price, we say that there is a loss. Loss = Cost Price - Selling Price  When C.P.>S.P. Loss = C.P. - S.P. S.P.= C.P.-Loss C.P.=S.P.+Loss Loss % = Loss/C.P. * 100 Loss = Loss % * C.P. When C.P.  and Loss % are given then, S.P. = C.P. * ((100-Loss %)/100) When ...
