There is more than one way to solve the problem. You can fill the three-gallon container, pour it into the five-gallon container, fill the three-gallon container again, and then pour into the five-gallon until it is full, leaving one gallon in the three-gallon container.

Five Gallons Alternative solution: Fill the 3 gallon container and pour it into the empty 5 gallon container. Fill the 3 gallon again and pour 2 gallons into the 5 gallon so that it is full, and 1 gallon will remain in the 3 gallon container. Empty the 5 gallon container. Pour the remaining 1 gallon from the 3 gallon container into the 5 gallon container.

The alternative solution for 'Five Gallons' is to fill the 3-gallon container, pour it into the 5-gallon container, and repeat the process to achieve 4 gallons in the 5-gallon container.

Q.4 from the easy section has an alternate answer using more moves but results in the same answer.

For the easy Five Gallons problem there is another answer, basically in reverse. It is less efficient though. You fill up the 7 gallon and fill up the 4 gallon, leaving 3 gallons. Empty the 4 gallon and pour the 3 gallons into the 4 gallon. Then fill up the 7 gallon and pour 1 gallon into the 4 gallon leaving 6 gallons.

I agree with the 3 gallon and 5 gallon but there are 2 solutions. You can fill the 3, pour into the 5, refill the three, pour into the five. Then empty the 5 and pour the one that was left over in the three into the five. Then fill the three and pour into the five to reach four gallons.

Five gallons fill at the half the 4 gallon bucket, fill all the 7 gallon bucket, and pour with the seven gallon bucket the 4 gallon bucket, 4/2=2, 7-2=5.

On Five gallons - much easier to just first fill three gallons into the five. Refill the three-gallon and fill the five-gallon. Now you have one gallon left in the little container. Empty the big container, and fill the one gallon from the three-gallon container into the five-gallon. Then just refill the three-gallon, and pour into the big one. Viola - 4 gallons.

There's an easier answer for the 2nd question. Fill both buckets halfway. One would be 2.5 liters and the other would be 1.5. Add the 1.5 liters to the 2.5 liters in the 5-liter bucket and you'd get 4 liters.
