    D Rs. 297.5 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 45% = 1.45 × 100y = Rs. ‘145y’ And, selling price of the article when it is sold at a loss of 35% = 0.65 × 100y = Rs. ‘65y’ According to the question, 145y – 65y = 150 Or, y = (150/80) Or, y = 1.875 So, cost price of article ‘A’ = 100 × 1.875 = Rs. 187.5 Therefore, cost price of article ‘B’ = 187.5 + 80 = Rs. 267.5
