Answers
Answer:
5:12
Step-by-step explanation:
Since shopkeeper gives 4 articles free on the purchase of 5 articles, he gives total 9 articles.
∴ Cost price of 9 articles = Rs. 900
Since the shopkeeper earns 20% profit:
∴ Amount collected by the shopkeeper = 900 × 1.2 = Rs. 1080
Since the shopkeeper get the price of only 5 articles
∴ Selling price of a article = 1080/5 = Rs. 216
Since the shopkeeper allows 10% discount
∴ Marked price of a article = 216/0.9 = Rs. 240
∴ Ratio of cost price and marked price of the article = 100 : 240 = 5 : 12
