Question

I bought 16 dozen pens and sold it at a loss equal to the Selling Price of 8 pens. What is the the Loss percent here?

Answer 1

Let the selling price of 8 pens be x
SP of 1 pen = x/8

Therefore SP of 16 dozen pens = 16*12*x/8
                                                    = 24x
Given loss = SP of 8 pens = x
Loss = CP - SP
CP = SP + Loss
CP = 24x + x
Thus, CP = 25x

Now, Loss percent = Loss/CP *100
                                 = x/25x *10
                                     = 4% loss
Hope that Helps !!
