Mohan bought some pens at the rate of ₹150/dozen. He sold them for Rs. 16 each. His profit percentage is ______%.

Correct option is A

Given:

Cost price = ₹150 per dozen

Selling price = ₹16 per pen

Formula Used:

​$$\text{Profit\%} = \dfrac{\text{SP} - \text{CP}}{\text{CP}} \times 100$$

Profit = Selling Price - Cost price

Solution:

​$$\text{CP per pen} = \dfrac{150}{12} = ₹12.50$$​​

Profit per pen = 16 - 12.50 = ₹3.50

​$$\text{Profit\%} = \dfrac{3.50}{12.50} \times 100$$ = 28%
