D Correct answer
Explanation

Total volume = 8.1 + 36.9 = 45.0 liters. The percentage of milk is (8.1 / 45.0) * 100 = (81 / 450) * 100 = (9 / 50) * 100 = 18%.

AI explanation

The total quantity of the mixture is the sum of milk and water, which is 8.1 liters plus 36.9 liters, equaling 45 liters. The percentage of milk is calculated as (8.1 / 45) multiplied by 100. This gives 810 divided by 45, which equals 18. The result is 18%.
