If the selling price of an article is 8% more than the cost price and the discount offered is 10% on the marked price of the article, then what is the ratio of the cost price to the marked price?

5 : 6 8 : 9 3 : 4 4 : 5

5 : 6

Direct concept = Ratio of CP to MP = (100% – Discount) : (100 + Profit) = (100 – 10) : (100 + 8) = 90 : 108 = 5 : 6
