What is the ratio of selling price to the cost price of an article, if there is a profit of 12%?

Correct option is C

Given:

Profit = 12%

Solution:

Let the cost price = 100 unit 

Then the selling price of the article = 100 + 100$$\times12 = 112$$ unit 

Ratio of the selling price to cost price = 112 : 100 = 28  : 25
