A shopkeeper marked an article 70% above its cost price
and made a profit of Rs. 275 when he sold the article after giving a discount of 25%. Find the profit percent earned by the shopkeeper if he had sold the article for Rs. 1350.Solution
Let cost price of the article is Rs. ‘x’ So, Selling price of the article = 0.75 × 1.7 × x = Rs. 1.275x According to question; 1.275x – x = 275 Or, 0.275x = 275 Or, x = 1000 Desired Percentage = [(1350 – 1000)/1000] × 100 = 35%
