10,7,3 = 5

[Mr. Laz]

You have a 10 gallon jug full of water
you have a 7 gallon empty jug
you have a 3 gallon empty jug

how do you get 2 jugs with 5 gallons of water in each using only these jugs.


(has nothing to do with antifreeze)

[seclark]

can we see the jugs?
sec

[The Franchise]

Pour 3 gallons from the 10 gallon jug into the 3 gallon jug.

Pour 5 gallons of water into the 7 gallon jug from the 10 gallon jug.

Pour 3 gallons from the 3 gallon jug into the 10 gallon jug.

10 gallon jug = 5 gallons

7 gallon jug = 5 gallons

3 gallon jug = empty

[crazycoffey]

pour half the water out of the 10 gal jug into the 7 gal jug, duh....

[The Franchise]

pour half the water out of the 10 gal jug into the 7 gal jug, duh....

Mine was better. :doh!:

[Dartgod]

Pour 3 gallons from the 10 gallon jug into the 3 gallon jug.

Pour 5 gallons of water into the 7 gallon jug from the 10 gallon jug.
Stop right there. How do you know you are pouring exactly 5 gallons into the 7 gallon jug? You had 7 gallons left after filling the 3 gallon jug.

How long do we have to do this before the bomb goes off?

:spock:ROFL It's early....leave me alone.

That's it! Now the mods are going to move this to the DC forum. ROFL

[DaFace]

Pretty sure you can't do this without at least being able to empty water out and refill jugs when you need to.

[Chazno]

Pour 6 gallons into the 7 gallon jar ( filing the 3 gal 2 x) --- 10(4 gallon) 7(6gallon) 3(empty)
Pour 3 gallons from 10 gallon to 3 gallon --- 10 (1 gallon) 7(6gallon) 3(3gallon)
Pour 1 gallon from 3 gallon into 7 gallon ---10(1 gallon) 7(7gallon) 3(2 gallon)
Pour 7 gallons from 7 gallon into 10 gallon ---10(8gallon) 7(empty) 3 (2 gallon)
Pour 2 gallons from 3 gallon into 7 gallon--- 10(8gallon) 7(2 gallon) 3(Empty)
Pour 3 gallons from 10 gallon in to 3 gallon ---10(5 gallon) 7(2 gallon) 3(3gallon)
Pour 3 gallons from 3gallon to 7 gallon ---10(5gallon) 7 (5gallon) 3 (empty)

[Dartgod]

I got it, but it took 9 steps...

Three Jugs: 10, 7, 3 (How much water in each: 10, 0, 0)

1. Fill the 7 gallon jug from the 10 gallon (3, 7, 0)
2. Fill the 3 gallon jug from the 7 gallon (3, 4, 3)
3. Empty the 3 gallon into the 10 gallon (6, 4, 0)
4. Fill the 3 gallon from the 7 gallon (6, 1, 3)
5. Empty the 3 gallon into the 10 gallon (9, 1, 0)
6. Empty the 7 gallon into the 3 gallon (9, 0, 1)
7. Fill the 7 gallon from the 10 gallon (2, 7, 1)
8. Fill the 3 gallon from the 7 gallon (2, 5, 3)
9. Empty the 3 gallon into the 10 gallon (5, 5, 0)

Done.

[Chief Chief]

Yeah, what he said...

How's mine not correct?

[Dartgod]

was mine not correct ????
Yeah, it works too. But it was 10 steps because your first step was technically 4 steps combined.

[DaFace]

Heh...apparently I suck.

[Chazno]

Yeah, it works too. But it was 10 steps because your first step was technically 4 steps combined.

Guess I missed that in the rules...

[Deberg_1990]

Wasnt this trick in "Die Hard with a Vengeance" ??

[wutamess]

Wasn't this on Die Hard?

[Phobia]

Generally I buy tools to reduce mental strain and man-hours. A new 5 gallon bucket is only $6. I'm gonna spend the money on the "tool".

This is why I own a business and other people figure out how to do something that should have taken 30 seconds in 3 hours.

[Phobia]

Hey - was this trick in Diehard?

[blueballs]

You take a tape measure and measure the height(edit:water line) of the ten gallon jug
You take a knife and puncture it at the half way mark
and catch the escaping water in the 7 gallon jug

[Phobia]

Show me a 10 gallon vessel that is not tapered.

[Rain Man]

Here in Colorado, we have illegal immigrants to do that kind of work. And they're cheap, so it doesn't really matter how long it takes.

[Blindside58]

Rent Die Hard: With a vengeance and have Samuel L. jackson tell you how to do it! And remember he is not yelling at you. "This is the way I talk!"

your best post to date....

[Mr. Laz]

.How's mine not correct?Stop right there. How do you know you are pouring exactly 5 gallons into the 7 gallon jug? You had 7 gallons left after filling the 3 gallon jug.

[Wa-Z]

How about filling up the 7 gal halfway (3.5) and the 3 gal halfway (1.5) and then combining the 2 into the 7 gal.

3.5 + 1.5 = 5

[Chief Chief]

How about filling up the 7 gal halfway (3.5) and the 3 gal halfway (1.5) and then combining the 2 into the 7 gal.

3.5 + 1.5 = 5

Your answer is illegal and thus incorrect since you're combining 3 steps into 1 step.

[Coogs]

I got it another way than Dartgod. took 10 steps though...

1. Pour 3 gallon into the 3 gallon jug (7 gal, 0 gal, 3 gal)
2. Pour the 3 gallon into the 7 gallon jug (7 gal, 3 gal, 0 gal)
3. Pour 3 more gal from the 10 gallon into the 3 gallon jug (4gal, 3 gal, 3 gal)
4. Pour the 3 gallon jug into the 7 gallon (4gal, 6 gal, 0 gal)
5. Pour 3 gal from the 10 gal into the 3 gal (1 gal, 6 gal, 3 gal)
6. Finish filling the 7 gallon from the 3 gallon (1 gal, 7 gal, 2 gal)
7. Dump the 7 gal back into the 10 gallon (8 gal, 0 gal, 2 gal)
8. Dump the 2 gal into the 7 gallon (8 gal, 2 gal, 0 gal)
9. fill the 3 gallon from the 10 gallon (5 gal, 2 gal, 3 gal)
10. dump the 3 gallon into the 7 gallon (5 gal, 5 gal, 0 gal)

[Dartgod]

I got it another way than Dartgod. took 10 steps though...

1. Pour 3 gallon into the 3 gallon jug (7 gal, 0 gal, 3 gal)
2. Pour the 3 gallon into the 7 gallon jug (7 gal, 3 gal, 0 gal)
3. Pour 3 more gal from the 10 gallon into the 3 gallon jug (4gal, 3 gal, 3 gal)
4. Pour the 3 gallon jug into the 7 gallon (4gal, 6 gal, 0 gal)
5. Pour 3 gal from the 10 gal into the 3 gal (1 gal, 6 gal, 3 gal)
6. Finish filling the 7 gallon from the 3 gallon (1 gal, 7 gal, 2 gal)
7. Dump the 7 gal back into the 10 gallon (8 gal, 0 gal, 2 gal)
8. Dump the 2 gal into the 7 gallon (8 gal, 2 gal, 0 gal)
9. fill the 3 gallon from the 10 gallon (5 gal, 2 gal, 3 gal)
10. dump the 3 gallon into the 7 gallon (5 gal, 5 gal, 0 gal)
That was the same solution that Chazno had, but he combined the first 4 steps:
Pour 6 gallons into the 7 gallon jar ( filing the 3 gal 2 x) --- 10(4 gallon) 7(6gallon) 3(empty)
Pour 3 gallons from 10 gallon to 3 gallon --- 10 (1 gallon) 7(6gallon) 3(3gallon)
Pour 1 gallon from 3 gallon into 7 gallon ---10(1 gallon) 7(7gallon) 3(2 gallon)
Pour 7 gallons from 7 gallon into 10 gallon ---10(8gallon) 7(empty) 3 (2 gallon)
Pour 2 gallons from 3 gallon into 7 gallon--- 10(8gallon) 7(2 gallon) 3(Empty)
Pour 3 gallons from 10 gallon in to 3 gallon ---10(5 gallon) 7(2 gallon) 3(3gallon)
Pour 3 gallons from 3gallon to 7 gallon ---10(5gallon) 7 (5gallon) 3 (empty)

Didn't see that one. I did the trick before I read any of the posts, and yours was the only one I saw.

[damaticous]

someone's been watching Die Hard huh?

[Jilly]

did you all see that thing on the news this morning about plastic jugs?

[luv]

someone's been watching Die Hard huh?

That's what I was thinking, but it's a little different. They only had two jugs.

[Calcountry]

Put a rock in the 10 gallon jug when it is half empty, that way you can flush, save the planet, AND reduce global warming. Al Gore told me so.

[Hog Rider]

Pour 6 gallons into the 7 gallon jar ( filing the 3 gal 2 x) --- 10(4 gallon) 7(6gallon) 3(empty)

Pour 3 gallons from 3gallon to 7 gallon ---10(5gallon) 7 (5gallon) 3 (empty)

problem is - how do you pour the one gallon from three?
Pour 3 gallons from 10 gallon to 3 gallon --- 10 (1 gallon) 7(6gallon) 3(3gallon)
Pour 1 gallon from 3 gallon into 7 gallon ---10(1 gallon) 7(7gallon) 3(2 gallon)

The 7 gallon has 6 in it.

[rad]

Someone probably already got it, but here goes:

Pour 3g from 10 to 3 g jug. Pour into 7g jug. (7/3/0)

Pour 3g from 10g to 3g jug. Pour into 7g jug again.(4/6/0)

Do it again, but only 1 gallon will fit in from 3g jug to 7 g jug (1/7/2)

Empty 7g into 10g jug (8/0/2)

Pour the 2g from the 3g jug into 7g jug (8/2/0)

Fill 3 g jug from 10g jug (5/2/3)

Pour 3g into the 7g jug (5/5/0)

[rad]

Dang!!!

[boogblaster]

Jug fillin' makes me dizzy ...

[Hog Rider]

The 7 gallon has 6 in it.

So you're sayin' 6 + 1 is 7?

I never got the connection Mr. Obvious, your a lifesaver, thanks!

and I read it a couple times :(
