You have a ten liter jug, an eight liter jug, and a five liter jug. Obtain exactly six liters of water in the 10 liter jug. You have only 23 liters of water.

1. Fill the 8 liter jug with water from the 10 liter jug.

2. Fill the 5 liter jug with water from the 8 liter jug. This leaves 3 liters in the 8 liter jug.
3. Pour out the water in the 5 liter jug.
4. Pour the remaining 3 liters from the 8 liter jug into the 5 liter jug.
5. Fill the 8 liter jug with water from the 10 liter jug.
6. Fill the 5 liter jug with water from the 8 liter jug. This leaves 1 liter in the 8 liter jug.
7. Pour the 5 liters from the 5 liter jug into the 10 liter jug.
8. Fill the 5 liter jug with water from the 10 liter jug.
9. You now have exactly 6 liters of water in the 10 liter jug.

And the water is already in the jugs, with no other place to store it

In that case, you can follow these steps to transfer the water:

1. Fill the 5-liter jug.
2. Pour the contents of the 5-liter jug into the 8-liter jug.
3. Fill the 5-liter jug again.
4. Pour the contents of the 5-liter jug into the 8-liter jug until the 8-liter jug is full (leaving 2 liters in the 5-liter jug).
5. Empty the 8-liter jug.
6. Transfer the 2 liters remaining in the 5-liter jug into the 8-liter jug.
7. Fill the 5-liter jug again.
8. Pour the contents of the 5-liter jug into the 8-liter jug.
9. You now have exactly 6 liters of water in the 10-liter jug.

That gets us seven liters of water!

I apologize for the oversight. Let's correct that and follow these steps:

1. Fill the 8-liter jug with water from the 10-liter jug.
2. Fill the 5-liter jug with water from the 8-liter jug. This leaves 3 liters in the 8-liter jug.
3. Pour out the water in the 5-liter jug.
4. Transfer the remaining 3 liters in the 8-liter jug to the 5-liter jug.
5. Fill the 8-liter jug again with water from the 10-liter jug.
6. Fill the 5-liter jug with water from the 8-liter jug. This will leave 6 liters in the 10-liter jug.

Follow these steps carefully to successfully achieve exactly 6 liters of water in the 10-liter jug. Thank you for your patience.

That got us five liters! Try AGAIN!

Here is the complete step-by-step process again to obtain exactly six liters of water in the 10-liter jug using the 10-liter, 8-liter, and 5-liter jugs:

1. Fill the 5-liter jug.
2. Pour the water from the 5-liter jug into the 8-liter jug.
3. Fill the 5-liter jug again.
4. Pour water from the 5-liter jug into the 8-liter jug until the 8-liter jug is full (this will leave 2 liters of water in the 5-liter jug).
5. Empty the 8-liter jug.
6. Transfer the 2 liters of water from the 5-liter jug to the 8-liter jug.
7. Fill the 5-liter jug again.
8. Pour water from the 5-liter jug into the 8-liter jug until the 8-liter jug is full (this will leave 1 liter of water in the 5-liter jug).
9. Fill the 10-liter jug from the 8-liter jug.

At the end of these steps, the 10-liter jug will have exactly 6 liters of water.

How do you get ONE liter in the five liter jug?

I apologize for the error. Let's correct that:

1. Fill the 8-liter jug with water from the 10-liter jug.
2. Pour the water from the 8-liter jug into the 5-liter jug, filling it.
3. Fill the 8-liter jug with water from the 10-liter jug.
4. Pour water from the 8-liter jug into the 5-liter jug until it is full (which will leave exactly 6 liters of water in the 10-liter jug).

Following these steps carefully will result in having 6 liters of water in the 10-liter jug. Thank you for your patience and understanding.
