A shopkeeper purchased an article for Rs. ‘a’ and marked it 135% above its cost price and sold it after giving two successive discounts of 200 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) = (2.35 × a – 200) × 0.80 Or, 1.8a = (2.35a – 200) × 0.80 Or, 2.25a = 2.35a – 200 Or, 0.10a = 200 Or, a = 2000 So, marked price of the article = 2.35 × 2000 = Rs. 4700
