      Question

      A shopkeeper purchased an article for Rs. β€˜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.
      A Rs. 5400 Correct Answer Incorrect Answer
      B Rs. 7680 Correct Answer Incorrect Answer
      C Rs. 2500 Correct Answer Incorrect Answer
      D Rs. 2250 Correct Answer Incorrect Answer

      Solution

      Selling price of the article = a + (4a/5) = Rs. (9a/5) So, (9a/5) = (2.5 Γ— a – 540) Γ— 0.80 Or, 1.8a = (2.5a – 540) Γ— 0.80 Or, 2.25a = 2.5a – 540 Or, 0.25a = 540 Or, a = 2160 So, marked price of the article = 2.5 Γ— 2160 = Rs. 5400
