Question

Radha purchased some pens .She sold all the pens .She sold 11 pens for rs 10 and incurred 30% loss In order to obtain 40% profit what should be the Selling rate?

Answer 1

Selling Price of 11 pens = Rs 10 (Given)

Find the Cost Price of 11 pens:

100 - 30 = 70%

70% = Rs 10

1% = 10 ÷ 70 = Rs 1/7

100% = 1/7 x 100 = Rs 14.29

Find the selling price to earn 40%:

40% profit = 40% x 14.29 = 0.4 x 14.29 = Rs 5.71

Find the selling price:

R14.29 + Rs 5.71 = Rs 20

Answer: The selling price will be Rs 20 for the 11 pens.
