A shopkeeper marked an article 70% above its cost price
and made a profit of Rs. 648 when he sold the article after giving a discount of 20%. Find the profit percent earned by the shopkeeper if he had sold the article for Rs. 2700.Solution
Let cost price of the article is Rs. ‘x’ So, Selling price of the article = 0.8 × 1.7 × x = Rs. 1.36x According to question; 1.36x – x = 648 Or, 0.36x = 648 Or, x = 1800 Desired Percentage = [(2700 – 1800)/1800] × 100 = 50%
