Question
A shopkeeper purchased an article for Rs. ‘a’ and
marked it 150% above its cost price and sold it after giving two successive discounts of 540 and 20%, respectively and earned a profit of Rs. 4a/5. Find the marked price of the article.Solution
Selling price of the article = a + (4a/5) = Rs. (9a/5) So, (9a/5) = (2.5 × a – 540) × 0.80 Or, 1.8a = (2.5a – 540) × 0.80 Or, 2.25a = 2.5a – 540 Or, 0.25a = 540 Or, a = 2160 So, marked price of the article = 2.5 × 2160 = Rs. 5400
