A Correct answer
Explanation

Average price = (1*18 + 2*24) / (1+2) = (18 + 48) / 3 = 66 / 3 = 22.

AI explanation

Using the weighted average formula, the average price equals (1 times 18 + 2 times 24) divided by the total quantity of (1 + 2). The calculation becomes (18 + 48) divided by 3, yielding a resulting mixture price of Rs. 22.
