Question

by selling 40 pens are shopkeeper suffers a loss of equal to the selling price of 5 pens find his loss percent

Answer 1

Let the selling price of 1 pen = 1 rupee.

Given that there are 40 pens.

Then the selling price of 40 pens = 40 rupees.

Given that he suffers a loss = 5 pens.

We know that Loss = CP - SP

                          5 = CP - 40

                          CP = 40 + 5

                          CP = 45.


We know that Loss% = Loss/CP * 100

                                    = 4/45 * 100

                                    = 8.88%.

Hope this helps!
