    Solution

    Let the cost price of article ‘A’ = Rs. ‘100y’ Then, selling price of the article when it is sold at a profit of 50% = 1.50 × 100y = Rs. ‘150y’ And, selling price of the article when it is sold at a loss of 40% = 0.60 × 100y = Rs. ‘60y’ According to the question, 150y – 60y = 180 Or, y = (180/90) Or, y = 2 So, cost price of article ‘A’ = 100 × 2 = Rs. 200 Therefore, cost price of article ‘B’ = 200 + 80 = Rs. 280
