Question

By selling 63 pens, a shopkeeper gains an amount equal to the selling price of 13 pens. Find his gain percentage​

Answer 1

Answer:

he gain profit of 26 %

Step-by-step explanation:

given

By selling 63 pen

gain profit = selling price of 13 pen

let the selling price of one pen is 1

then

SP of 63 pen = 63

profit = SP of 13 pen = 13  

so we can find CP of all 63 pen

CP = SP - profit

CP = 63 - 13 = 50

CP = 50

SP = 63

profit = 13

so profit percent = (profit / CP ) ×100

= (13/50)×100

= 13×2 = 26 %

profit = 26%
