51.
The answer is: D
Explanation
Let's break it down step by step in simple terms:
- The number of eggs doubles each day.
- On the 24th day, the basket is completely full.
- This means on the 23rd day, the basket was half full (since it doubles the next day).
- On the 22nd day, the basket was 1/4th full (because it doubles to 1/2 on the 23rd day).
Answer:
The basket was 1/4th full on the 22nd day.
Correct option: D: 22.
