Question

A shopkeeper buys 1 dozen of pens at Rs 15 each and sells them at Rs 18

ch. Find his profit and profit percent.​

Answer 1

20%

Explanation:

Cost price (C. P.) of each pen = ₹ 15

Selling price (S. P.) of each pen = ₹ 18

Profit = S. P. - C. P. = 18 - 15 = ₹3

`profit \: percent \\ \\ = (profit)/(c.p.) * 100 \\ \\ = (3)/(15) * 100 \\ \\ = (3)/(3) * 20 \\ \\ = 20\%`
