sumit purchased 35 pens at the rate of 5 pens for ₹ 22 and sold them at the rate of 4 pens for ₹ 22. find out his profit percent.

Answer 1

total pens = 35


cost of 5 pens = ₹22


cost of 1 pen = 22 ÷ 5 = ₹4.4



cost of 35 pens = 35 × 4.4 = ₹154


s.p of 4 pens = ₹22


.s.p of 1 pen = 22 ÷ 4 = ₹5.5


s.p of 35 pens = 35 × 5.5 = ₹192.5


Find the profit:
----------------------

profit = s.p - c.p = 192.5 - 154


profit = ₹38.5


Find the profit%:
-----------------------

profit % = (profit× 100)/ c.p


= (38.5 × 100)/ 154 = 25%



Answer: profit = 25%
