B Correct answer
Explanation

Initial mixture: 80 gm with 60% milk = 48 gm milk, 32 gm water. Removing 20 gm removes proportionally: 48 × (20/80) = 12 gm milk, 32 × (20/80) = 8 gm water. Remaining: 36 gm milk, 24 gm water. Adding 6 gm water: 36 gm milk, 30 gm water. Ratio = 36:30 = 6:5. Option B is correct.
