You have a bucket that holds 4 gallons of water and another bucket that holds 7 gallons of water. You must go the lake and bring back exactly 5 gallons. How would this be done?

1. Fill 7 gallon jug
2. Put 4 gallons into 4 gallon jug from 7 gallon jug
3. Throw away 4 gallons jug
4. Put 3 gallons from 7 gallon jug into 4 gallon jug
5. Put 7 gallons into 7 gallon jug
6. Put 1 gallon into 4 gallon jug from 7 gallon jug
7. Throw away 4 gallons from 4 gallon jug
8. Put 4 gallons from 7 gallon jug into 4 gallon jug
9. Throw away 4 gallons from 4 gallon jug
10. Put 2 gallons from 7 gallon jug into 4 gallon jug
11. Fill 7 gallon jug
12. Put 2 gallons from 7 gallon jug into 4 gallon jug
13. You now have 5 gallons in the 7 gallon jug.

Lol I just did that in my head.

Fill the 7gal bucket
With it fill the 4 gallon bucket leaving 3 gallons in the 7 gallon bucket.

Dump the 4 gallon bucket then fill it halfway.

5 gallons. Does that work for you? :)

Edit: aah shucks, the monk beat me with a much more exacting answer.

Lol fill it halfway, you are a little cheat!

Hehe :D

Just fill the 7 gallon bucket up to the 5 gallon mark

Right? :P

Too complicated Monkey Boy. Jeez, you scientists over think everything.

Fill the 4 gallon bucket. Pour into 7 gallon bucket.
Refill the 4 gallon bucket. Pour into 7 gallon bucket.
You will be left with 1 gallon in the 4 gallon bucket. Dump the 7 gallon bucket out and pour the remaining 1 gallon into the 7 gallon bucket.
Refill the 4 gallon bucket and pour into 7 gallon one. You now have 5 gallons in that bucket.

Have to spread the love rube :)

Pour the 4 gallon bucket into the 7gallon 2 times- you have 1 gallon left in the 4 gallon bucket. Empty the 7 gallon bucket back into the lake. Then pour in the remaining 1 gallon in the 4 gallon bucket, and pour in another 4 gallons.
