    Solution

    Let the cost price of article 'A' be Rs. 'p'. So, cost price of article 'B' = Rs. (1,120 - p) Mark price of article 'A' = Rs.1.25p Marked price of article 'B' = 1.4 X (1,120 - p) = Rs. (1,568 - 1.4p) Selling price of article 'A' = 0.9 X 1.25p = Rs. 1.125p Selling price of article 'B' = 0.9 X (1,568 - 1.4p) = Rs. (1,411.2 - 1.26p) ATQ, 1.125p + 1,411.2 - 1.26p = 1,338.3 Or, 0.135p = 72.9 Or, 'p' = 540 Therefore, cost price of article 'A' is Rs. 540.
