Question

Two equal glasses of the same type are respectively 1/3 and 1/4 full of milk. The glasses are then filled to the brim by adding water and the contents are mixed in a pot. What is the ratio of water to milk in the pot?

1. A. 3 : 1
2. B. 7 : 3
3. C. 11 : 7
4. D. 17 : 7 (Correct answer)

Correct Answer

Option D — 17 : 7

Detailed Solution & Explanation

The correct answer is 17 : 7.

Key Points

• Let glass capacity = 12 units (LCM of 3 and 4).
• Glass 1: milk = 4, water = 8. Glass 2: milk = 3, water = 9. Mixed: total milk = 4+3 = 7, total water = 8+9 = 17. Ratio water:milk = 17:7. This is a standard mixture and alligation problem.
