Single correct option
A vessel contains 24 litres of a milk-water mixture in the ratio 5:3. 8 litres of this mixture is removed and replaced with pure water. What is the new ratio of milk to water?
- A. 3:5
- B. 5:7
- C. 2:3
- D. 5:8
Show answer and solution
Answer: (B) 5:7
Initial milk = 24×5/8 = 15 L, water = 9 L. Removing 8 L of mixture removes milk and water in the same 5:3 ratio: milk removed = 8×5/8 = 5 L, water removed = 3 L. Remaining milk = 10 L, remaining water = 6 L, and 8 L of water is added back, so water = 6+8 = 14 L. New ratio = 10:14 = 5:7.
