The profit percentage on the three articles A , B and C is 10%,20% and 25% and the ratio of the cost price is 1 : 2 : 4 . Also the ratio of number of articles sold of A , B and C is 2 : 5 : 2 then the overall profit percentage is :
Correct Answer: 21 %
Explanation:
CP of A + B + c = 2xy + 5x*2y - 2x*4y = 20xy profit of A = 0.2xy
profit of B = 2xy
profit of C = 2xy
Total profit = 4.2xy % profit = (4.2xy / 20xy) X 100 = 21%
