(f) If the S.P is greater than the C.P, there has been a profit.
(g) If the S.P is lower than the C.P, there has been a loss.
(h) If the product is sold at the same price as the cost, there has been no loss or profit.

Important Formulae
-> Profit/Gain = S.P - C.P
-> Loss = C.P - S.P
-> Profit/Loss Percentage = S.P-C.P/C.P * 100
-> Loss % = Loss*100/C.P
-> Profit % = (Profit * 100)/C.P
