Question
A shopkeeper marked an article 65% above its cost price
and made a profit of Rs. 644 when he sold the article after giving a discount of 15%. Find the profit percent earned by the shopkeeper if he had sold the article for Rs. 2000.Solution
Let cost price of the article is Rs. ‘x’ So, Selling price of the article = 0.85 × 1.65 × x = Rs. 1.4025x According to question; ⇒ 1.4025x – x = 644 ⇒ 0.4025x = 644 ⇒ x = 1600 Desired Percentage = [(2000 – 1600)/1600] × 100 = 25%
