Explanation

Initial: 50L milk. After first operation: 40L milk + 10L water. After second operation: removing 10L of mixture (proportionally 8L milk, 2L water) and adding 10L water gives 32L milk + 18L water. The milk:water ratio is 32:18 = 16:9. Option A reverses the ratio. Options C and D are incorrect ratios.
