4 : 5

2 : 3

1 : 2

- To determine the correct ratio, use the concept of weighted averages (also known as the rule of alligation).

- You want a mixture costing ?15 per kg from two varieties costing ?10 and ?30 per kg.

- Set up the equation for the alligation method: (Cost of higher priced item - Cost of mixture) : (Cost of mixture - Cost of lower priced item).

- This translates to (30 - 15) : (15 - 10) = 15 : 5.

- Simplify the ratio 15 : 5 to get 3 : 1.

Options:

1. 3 : 1 - This is the correct answer based on the calculations.

2. 4 : 5 - Incorrect, as it does not match the ratio derived.

3. 2 : 3 - Incorrect, doesn't align with calculated ratio.

4. 1 : 2 - Incorrect, doesn't match derived ratio.
