- The initial mixture is 30 liters with 15% water, so it contains 4.5 liters of water (15% of 30 liters).

- This means there are 25.5 liters of milk in the mixture.

- To achieve 37.5% water concentration, we must calculate the total water needed when mixed with the existing milk volume.

- The equation becomes: (4.5 + x) / (30 + x) = 0.375, where x is the added water in liters.

- Solving for x gives x = 7.2 liters.

- Correct Answer: 7.2 liters
