Question
The sum of the cost prices of two articles, 'C' and 'D',
is Rs. 480. Both articles are marked up by 60%, whereas the marked price of article 'D' is Rs. 120 more than that of article 'C'. Find the marked price of article 'D'.Solution
ATQ, Let the cost price of article 'C' and 'D' be Rs. 'x' and Rs. 'y', respectively. So, x + y = 480 ............(I) And, 1.60(y - x) = 120 So, y - x = 75 .............(II) Adding equations (I) and (II), we get, x + y + y - x = 480 + 75 Or, 2y = 555 So, 'y' = (555/2) = 277.5 Therefore, marked price of article 'D' = 277.5 x 1.60 = Rs. 444
