C Correct answer
Explanation

Let juice = 4x and water = 3x. Adding 2 litres of water gives (4x) / (3x + 2) = 4 / 5. Solving for x: 20x = 12x + 8, so 8x = 8, x = 1. Juice = 4x = 4 litres.

AI explanation

Let the initial quantities of juice and water be 4x and 3x respectively. Adding 2 litres of water makes the new ratio 4x to (3x + 2), which equals 4/5. Solving the equation 20x = 12x + 8 yields x = 1. The quantity of juice is 4x, which calculates to 4 litres.
