Solution

## The correct option is A 21%Let CP of A, B, C be 100, 200, and 400 respectively. Then profit for A, B, C = 10, 40, and 100 respectively. Let the number of articles sold be 2, 5, 2 respectively for A, B, and C. Total profit = 2×10+5×40+2×100=420 Total CP = 2×100+5×200+2×400=2000 Overall profit percentage = 4202000×100=21%. Alternate Approach: CP of A+B+C=2x×y+5x×2y+2x×4y=20xy Profit of A = 0.2xy Profit of B = 2xy Profit of C = 2xy Total profit = 4.2xy % profit =4.2xy20xy×100=21%
