Question
The sum of the cost prices of two articles, 'A' and 'B',
is Rs. 680. Both articles are marked up by 50%, whereas the marked price of article 'B' is Rs. 150 more than that of article 'A'. Find the marked price of article 'B'.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
