A shopkeeper marked an article 70% above its cost price
and made a profit of Rs. 742 when he sold the article after giving a discount of 10%. Find the profit percent earned by the shopkeeper if he had sold the article for Rs. 2100.Solution
Let cost price of the article is Rs. ‘x’ So, Selling price of the article = 0.9 × 1.7 × x = Rs. 1.53x According to question; 1.53x – x = 742 Or, 0.53x = 742 Or, x = 1400 Desired Percentage = [(2100 – 1400)/1400] × 100 = 50%
