In a mixture, the ratio of the milk and water is 6 : 5. when 22 liter mixture is replaced by water, the ratio becomes 9 : 13. Find the quantity of water after replacement. Correct Answer 52 liter

Correct Option: DLet milk = 6x, water = 5xAccording to the question, 6x – 22 × 6 : 5x – 22 × 5 + 22 = 9 : 13 11 11 6x – 12 : 5x – 10 + 22 = 9 : 1313 (6x – 12) = 9 (5x + 12)78x – 156 = 45x + 10878x – 45x = 156 + 10833x = 264x = 8Water after replacement = 5 × 8 – 10 + 22 = 40 + 22 = 52 litreHence, option D is correct.
