Question

A wholesale dealer sell 40 pens at the MP of 36 pens and the retailer sells them to customer at 1% discount find its profit%?​

Answer 1

Answer:

Retailer buys at 10% discount on marked price.

Lets say the marked price is x.

36 pens will cost 36x.

So buying price of each pen is 36x/40=9x/10=0.9x .

Selling price is at a discount of 1% on marked price x, that is, at 0.99x .

So effectively the profit per pen is selling price minus buying price 0.99x−0.9x=0.09x .

Thus profit% is 0.09x/x∗100=9 .
