C Correct answer
Explanation

Assume the total cost of the stock is 100 units. Two-thirds earns 20% profit and one-third earns 14% profit. The weighted gain is (2/3 x 20) + (1/3 x 14) = 18%, corresponding to option C.

AI explanation

Using the weighted average method, the overall gain percentage is (2/3 * 20) + (1/3 * 14). This calculates to 40/3 + 14/3, which equals 54/3 or 18%. The total gain is 18%.
