Nitin bought some pencils at the rate of ₹180 a dozen. He sold them for ₹17 each. His profit percentage is ______%. (Round off to two decimal places.)

Correct option is D

Given:

Cost price = ₹180 per dozen

Selling price = ₹17 per pencil

Find profit percentage (round to two decimals)

Formula Used:

Profit % = $$\frac{\text{Profit}}{\text{CP}} \times 100$$​​

Solution: 

CP per pencil = $$\frac{180}{12} = 15$$​​

Profit = 17 − 15 = 2

Profit% = $$\frac{2}{15} \times 100$$​ = 13.3333%
