Question

DUDE
Andrew purchased 20 pens and sold 16
them for the same amount as the total cost
20 pens. What is the profit percentage?​

Answer 1

Answer:

25%

Step-by-step explanation:

let the cost of 20 pens be x rs.

=> cost of 1 pen= x/20

selling price of 16 pen = x rs.

=> selling price of 1 pen= x/16

profit= selling price-cost price

        =x/16- x/20

         =x/80

profit percentage= profit amount/cost price*100

                               =x/80/x/20*100

                                =1/4*100

                                =25
