      Solution

      Let the cost price of article β€˜A’ = Rs. β€˜100y’ Then, selling price of the article when it is sold at a profit of 32% = 1.32 Γ— 100y = Rs. β€˜132y’ And, selling price of the article when it is sold at a loss of 40% = 0.60 Γ— 100y = Rs. β€˜60y’ According to the question, 132y – 60y = 810 Or, y = (810/72) Or, y = 11.25 So, cost price of article β€˜A’ = 100 Γ— 11.25 = Rs. 1125 Therefore, cost price of article β€˜B’ = 1125 + 80 = Rs. 1205
