Measuring 7 Liters Puzzle - Solution

The Puzzle:

Jack and Jill did not have much success when they went up the hill to fetch a pail of water from the well. However, once they had both tumbled down the other side they found the pond and decided to get the water from there instead.



The problem was that they wanted 7 litres exactly. Jack's bucket held 5 litres and Jill's bucket held 3 litres. How did they bring back 7 litres? No guessing!

Our Solution:

One possible method follows:

1. Fill up the 5 litre bucket

2. Pour the 5 litre bucket into the 3 litre bucket until the 3 litre bucket is full.



3. Empty the 3 litre bucket.

4. Pour the remaining 2 litres from the 5 litre bucket into the 3 litre bucket.

5. Fill up the 5 litre bucket again.
