Question
A shopkeeper purchased an article for Rs. lsquo;arsquo;
and marked it 160% above its cost price and sold it after giving two successive discounts of 350 and 25%, 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) = (2.6a - 350) x 0.75 Or, 1.8a = (2.6a - 350) x 0.75 Or, 2.4a = 2.6a - 350 Or, 0.2a = 350 Or, a = 1750 So, marked price of the article = 2.6 x 1750 = Rs. 4550
