Question
Two successive discounts of 20% and 30% are given while
selling an article. What is the ratio of the marked price of the article to its selling price?Solution
Let's assume the marked price of the article is '100y'. Two successive discounts of 20% and 30% are given while selling an article. Selling price of the article = 100y of (100-20)% of (100-30)% = 100y of 80% of 70% = 56y Ratio of the marked price of the article to its selling price = 100y : 56y = 25 : 14
