A shopkeeper purchased an article for Rs. ‘a’ and marked it 140% above its cost price and sold it after giving two successive discounts of 480 and 20%, respectively and earned a profit of Rs. 4a/5. Find the marked price of the article.
Selling price of the article = a + (4a/5) = Rs. (9a/5) So, (9a/5) = (2.4 × a – 480) × 0.80 Or, 1.8a = (2.4a – 480) × 0.80 Or, 2.25a = 2.4a – 480 Or, 0.15a = 480 Or, a = 3200 So, marked price of the article = 2.4 × 3200 = Rs. 7680
