                    1)  When S.P> C.P , it is a situation of Profit
                         Type 1
                         Profit= S.P- C.P




                         Type-2







                    2)  When S.P<C.P , it is a situation of Loss

                            Loss= CP- SP
                                  loss
                            Loss%=     100
                                  CP

                  NOTE:
                       Profit or loss are normally calculated on cost price.
                       Additional expenses made after buying an article are included in the cost price
                         and are known as overhead expenses.

                       CP = Buying price + Overhead expenses
                       If there is a profit of P %,
                         Cost Price = C
                         Sale price= SP
                                         100
                         Then C =                  x SP
                                    100  Profit %
                         If there is a loss of L %,
