Two successive discounts of 20% and 30% are given while selling an item. What is the ratio of the marked price to the selling price of the item?

25 : 14

Let the marked price of the article = 100

Two successive discounts of 20% and 30%

Successive discount =  x + y - \(\frac{x × y}{100}\)

Successive discount =  20 + 30 - \(\frac{20 × 30}{100}\) = 44%

Now the selling price of the article = 100 - 44 = 56

MP : SP = 100 : 56 = 25 : 14
