    C Rs. 409.5 Correct Answer Incorrect Answer
    D Rs. 400.5 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the cost price of article ‘A’ = Rs. ‘100y’ Then, selling price of the article when it is sold at a profit of 40% = 1.40 × 100y = Rs. ‘140y’ And, selling price of the article when it is sold at a loss of 40% = 0.60 × 100y = Rs. ‘60y’ According to the question, 140y – 60y = 270 Or, y = (270/80) Or, y = 3.375 So, cost price of article ‘A’ = 100 × 3.375 = Rs. 337.5 Therefore, cost price of article ‘B’ = 337.5 + 72 = Rs. 409.5
