A Correct answer
Explanation

Using the alligation rule: (60 - 48) / (48 - 40) = 12 / 8 = 3 / 2.

AI explanation

Using the rule of alligation, the ratio of the quantities is the difference between the second cost and the mean price to the difference between the mean price and the first cost. This calculation is (60 minus 48) divided by (48 minus 40), resulting in 12 divided by 8. This fraction simplifies to a ratio of 3:2 for the first container to the second container.
