Question

Peter purchased 35 pens at a rate of 5 pens for ₹22 and sold them at a rate of 4 pens for ₹22. Find out his profit percent.

Answer 1

As we know that the formula of profit percent

Profit percent = [ (SP - CP) / CP] × 100%

Selling price = 22 Rs
one pen = 5 Rs
Cost price of 4 pens = 4×5
= 20 Rs

Profit percent = [ ( 22 - 20) / 20] × 100%
= (2/20) × 100%
= (1/10) × 100%
= 10%
