Question
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 300 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) = (2.4 ×  a - 300) ×  0.80 Or, 1.8a = (2.4a - 300) ×  0.80 Or, 2.25a = 2.4a - 300 Or, 0.15a = 300 Or, a = 2000 So, marked price of the article = 2.4 ×  2000 = Rs. 4800
