Question

A retailer marks his goods at 35%above the cp and allow a discount of 20%on the mp . find his gain %or lose.%

Answer 1

Let the CP be Rs.X.
MP of the goods= CP+ 35%OF CP
                          = RS. X +35% * X
                          = RS.27x/20
Discount %        = 20%
SP of the goods = (1-d/100) * MP
                           = (1-20/100)* Rs.27x/20
                           = 4/5 * Rs.27x/20
                           = Rs. 27x/25
Profit                   = SP-CP
                            = RS. 27x/25 - Rs. x
                            = Rs.2x / 25
Profit%                = Profit / CP*100
                            =( RS. 2x/25 ) /RS.x *100
                            = 8%
Ans.= The retailer had a profit of 8%.
