Solution:

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 =

{4 .2 x y × 10 0}/{20xy}=21%
