Ratio of CP given as 1:2:4. Let cost of, A = x, B = 2x and C = 4x Ratio of number of articles sold is given as 2:5:2. Let number of items sold be, A = 2y, B = 5y and C = 2y Total cost (A + B + C), = (2xy + 10 xy + 8xy) = 20xy Profit of A = 0.2xy Profit of B = 2xy Profit of C = 2xy Total profit = 4.2xy % Profit =
