Question

By selling 50 pens , a shopkeeper is gaining selling price of 5 pens and cost price of 10 pens , find out his percentage profit on selling price

Answer 1

Answer:

Let us suppose that the selling price of 1 pen is Rs 1

Hence, when the shopkeeper sells 50 pens then the selling price of 50 pens will be Rs 50

Now, we have been given that the shopkeeper gained the amount equal to the selling price of 10 pens.

So, 1 pen costs 1 rupee then

Profit (P) =10

S.P.=50

So, C.P.=40

P%=(10×100)/40

P%=25
