By selling an article, a shopkeeper makes a profit of 30% of its selling price. Find his profit percentage.

Correct option is C

Given:

Profit on Selling Price =30%

Formula Used:

Profit = Selling Price - Cost Price

Profit Percentage =$$\frac{Profit}{Cost\ Price} \times 100$$​

Solution:

Let the Selling Price be 100

Then Profit = 30% of 100 = 30

Cost Price = 100 - 30 = 70

Profit Percentage =$$\frac{30}{70} \times 100 = 42\frac{6}{7}\%$$​​
