Question

You have two drums. One is three gallons and the other is five. You have an unlimited supply of water but need to get exactly four gallons. How could you do it?"

Answer 1

Die Hard 3...You fill up the 5 and pour it into the 3 - that leaves you with two. Then you dump out the 3 gallon. Pour the 2 from the 5 into the 3. Then fill up the 5 and fill up the 3 (there is only 1 gallon left) leaving you with 4 gallons in the 5.

Answer 2

Fill the 3 gallon drum and pour it into the five gallon drum. Fill the 3 gallon drum up again and with it top off the 5 gallon drum leaving 1 gallon left in the 3 gallon drum, Emplty the 5 gallon drum and pour the 1 gallon (that it in the 3 gallon drum) into the 5 gallon drum. Fill the 3 gallon drum up and pour that into the 5 gallon drum and you then have 4 gallons in the 5 gallon drum.

Answer 3

simple,

1) fill the 3 gallons of water into the 5 gallon using the 3 gallon drum.

2) then fill the 3 gallon drum completely with water and pour it into the 5 gallon drum. you'll be left with 1 gallon in the 3 gallon drum ( because 6-5 =1 gallon).

3) then empty the 5 gallon and pour the 1 gallon from the 3 gallon drum into the 5 gallon.

4) then fill the 3 gallon drum completely ( =3 gallons) and pour it into the 5 gallon drum ( 1+3 = 4 gallons)

Answer 4

Hey,

you fill the 3 gallons drum, and u empty it in the 5 gallon drum. Then u fill the 3 gallons drum again, and u pour that in the 5 gallon drum. Now, the five gallon drum contains 5 gallons, and there's 1 gallon left in the 3 gallons drum. U completly empty the 5 gallon drum, pour the remaining 1 gallon from the 3 gallon drum to the empty 5 gallon drum. Finally u fill the 3 gallon drum, and u pour it in the 5 gallon drum. U now have 4 gallons in ur 5 gallon drum.
