B Correct answer
Explanation

Using alligation: (24 - 20) : (20 - 18) = 4 : 2 = 2 : 1.

AI explanation

Using the rule of alligation, the ratio of the quantity of the cheaper sugar to the dearer sugar is calculated as (24 - 20):(20 - 18). This simplifies to 4:2, making the required mixing ratio 2:1.
