Answer
Correct Answer: 7:3
Explanation
Step 1: Understand the ratios
Vessel A ratio = 4:1 (Milk:Water) ⇒ Milk = 4/5, Water = 1/5
Vessel B ratio = 3:2 (Milk:Water) ⇒ Milk = 3/5, Water = 2/5
Step 2: Take equal quantities from A and B
Assume 1 litre from A and 1 litre from B
From A (1 litre): Milk = 4/5 litre, Water = 1/5 litre
From B (1 litre): Milk = 3/5 litre, Water = 2/5 litre
Step 3: Total in vessel C
Total milk = 4/5 + 3/5 = 7/5 litres
Total water = 1/5 + 2/5 = 3/5 litres
Step 4: Find the ratio of milk to water
Milk : Water = (7/5) : (3/5) = 7 : 3
Answer: 7 : 3
