Explanation:

- Statement I: Ravi eats 2 eggs and then pauses for 12 seconds each time. We don't know his total time to finish 24 eggs. This alone can't tell us who finishes first.

- Statement II: Harish finishes eating 24 eggs in 7.5 minutes. This only gives us Harish's time.

- Combining both statements: We can calculate Ravi's time based on his eating and resting pattern. Compare this time with Harish's 7.5 minutes to determine who finishes first.

- Correct Answer: Option 3, as both statements are needed to determine who finishes first.
