How do you measure 4 gallons with only a 5 gallon and a 3 gallon bucket?
1.Dump 3 gal into 5 gal 2. Fill 3 ga and empty into 5 gal again 3. This will leave 1 gal in the 3 gal 4. Dump the 5 gal 5.Add the 1 gal from the 3 gal to the 5 gal 6. Fill the 3 gal again 7. Dump the 3 gal into the 5 gal (where there is all ready 1 gal) 8. Now there are 4 gallons of water in the 5 gallon bucket.
Shift some water from the 5 gallon bucket to 3 gallon bucket to make both the buckets have same amount of water. when both the buckets have same amount of water. That means both contain 4 gallons of water.
From the full 5 gallon bucket, you get the 3 gallons needed to make the smaller bucket full. You now have 2 gallons remaining in the big bucket. Then you empty the 3 gallon bucket and drop the residual 2 gallons from the big one into it. Then you mark the 2 gallon level in the 3 gallon bucket. Now you can drop the two gallons back into the big bucket, then go by the mark to collect two more gallons in the small bucket and drop again into the big bucket, whence you obtain 2+2 = 4 gallons.
