    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ, Let the cost price of article 'A' and 'B' be Rs. 'x' and Rs. 'y', respectively. So, x + y = 680 ............(I) And, 1.50(y - x) = 150 So, y - x = 100 .............(II) Adding equations (I) and (II), we get, x + y + y - x = 680 + 100 Or, 2y = 780 So, 'y' = (780/2) = 390 Therefore, marked price of article 'B' = 390 x 1.50 = Rs.585
