A Correct answer
Explanation

The initial mixture of 35 L with a 4:1 ratio contains 28 L of milk and 7 L of water. Adding 7 L of water results in 28 L of milk and 14 L of water. The new ratio is 28:14, which simplifies to 2:1.

AI explanation

In the original 35 liter mixture, the 4 to 1 ratio means there is 28 liters of milk and 7 liters of water. Adding 7 liters of water increases the water volume to 14 liters, while the milk volume remains 28 liters. The new mixture has a total volume of 42 liters. The ratio of milk to water in the new mixture is 28 to 14, which simplifies to 2 to 1.
