Ratio of CP given as 1 : 2 : 4Let cost of,
A = x
B = 2x
C = 4x
Ratio of Number of sell is given as 2 : 5 : 2
Let number of items sold be,
A = 2y
B = 5y
C = 2y
Total cost (A + B + C), = (2xy + 10xy + 8xy)
= 20xy
Profit of A = 0.2xy
Profit of B = 2xy
Profit of C = 2xy
Total profit = 4.2xy
% Profit = $$\frac{{4.2{\text{xy}} \times 100}}{{20{\text{xy}}}} = 21\% $$
