Question

how do you get exactly 4 gallons on a scale (being acurate) with a 5 and a 3 gallon jug?

Answer 1

(1) Fill the five gallon jug. Three gallon jug is empty.

(2) Empty three gallons from the five gallon jug into the three gallon jug.

(3) There remains two gallons in the five gallon jug. Empty the three gallon jug.

(4) Pour the two gallons into the three gallon jug.

(5) Fill the five gallon jug and pour one gallon from it into the three gallon jug - filling the three gallon jug.

(6) Four gallons remain in the five gallon jug.

Answer 2

Fill a five gallon jug completely. From the full five gallon jug dump contents into three gallon jug until it is full. This will leave 2 gallons in the 5 gallon jug. Mark the point where this comes to in the 5 gallon jug. Now empty the 3 gallon jug. Now take the 2 gallons and empty it into the 3 gallon jug. Next fill the 5 gallon jug to the point you previously marked as 2 gallons. Now the 5 gallon jug contains 2 gallons and the 3 gallon jug contains 2 gallons.

Answer 3

There's a few different ways but here's one. Fill the 5 gallon jug full of water. Pour the water from the 5 gallon jug into the three gallon jug leaving 2 gallons left in the 5 gallon jug. Dump the three gallon jug out and pour the 2 gallons from the 5 gallon jug into the 3 gallon jug. Refill the 5 gallon jug full again - then pour this water into the remaining space of the three gallon jug. There's only room for one gallon to pour out leaving four gallons left in the five gallon jug.

Answer 4

Fill the 5 gallon jug and pour into the 3 gallon jug, leaving 2 gallons of water in the 5 gallon jug. The 3 gallon jug is emptied and 2 gallons from the 5 gallon are poured into it, which leaves 1 gallon of empty space. Youn then fill the 5 gallon jug and empty one gallon from the 5 gallon into the 3 gallon jug, leaving exactly 4 gallons in the 5 gallon jug. BAM--its from Die Hard with a vengeance

Answer 5

4) pour from the 5 gallon jug into the 3 gallon bucket until full.
5) the remaining fluid inside the 5 gallon jug will be 4 gallons as long as your fill lines are accurate.

Answer 6

sh it this was a question on a math test once and i got it right but totally dont remember.

ohh i got it!!

fill up the 5 gallon jug and dump it all in the three gallon so you have 2 gallons left over in the 3 gallon jar...

then fill up the 5 gallon jar again and fill the 2 gallon jar to the top so that would be one gallon... and then you have 4 gallons in the 5 gallon jar!!

Answer 7

To get four gallons, fill the three gallon jug, and dump it into the five gallon jug. Fill the three gallon jug again, and dump what you can into the five gallon jug. Now there is one gallon in the three gallon jug. Dump out the five gallon jug, and put the one gallon from the three gallon jug into the five gallon jug. Now fill the three gallon jug. The total is four gallons.
