Question

Jack and will 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 Jacks bucket held 5 litres and
Jill's bucket held 3 litres. How did they bring back 7 liters? No guessing!
​

Answer 1

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
