If I have a bucket of water that holds 4 gallons of water and another bucket that holds 7 gallons of water. The buckets have no markings. How can I go to the well and bring back exactly 5 gallons?
Fill the 4 gal bucket and empty it into the 7 gal bucket. Fill the 4 gal bucket and then fill the 7 gal bucket from the 4 gal. This leaves 1 Gallon in the 4 gallon bucket. Empty the 7 gallon bucket and pour the gallon from the 4 gal lbucket into it. Fill the 4 gal bucket and pour it into the 7 gal bucket. You then have 5 gallons in the 7 gallon bucket.

# Start with empty buckets, and carry them to the well. # (Note that the larger is the 7-gallon bucket, and the smaller is the 4-gallon bucket.) # Fill the 4-gallon bucket with water to the top. # Empty all the water from the 4-gallon bucket into the 7-gallon bucket. # (Note that there is room in the 7-gallon bucket for exactly 3 more gallons.) # Fill the 4-gallon bucket again. # Pour from the 4-gallon bucket into the 7-gallon bucket all the water that will fit, spilling none. # (Note that since there was room for only 3 more gallons in the 7-gallon bucket, you now have 1 gallon left in the 4-gallon bucket.) # Dump out all the water from the 7-gallon bucket. (Pour it back into the well or onto some flowers so it's not wasted.) # Pour the 1 gallon of water that remains in the 4-gallon bucket into the empty 7-gallon bucket. # Refill the 4-gallon bucket completely. # Pour all the 4 gallons from the 4-gallon bucket into the 7-gallon bucket. # (Note that since the 7-gallon bucket had 1 gallon already and you added 4 gallons, you now have 5 gallons of water in the 7-gallon bucket!) # Bring back your 7-gallon bucket that's holding exactly 5 gallons of water. (Bring your 4-gallon bucket back too, in case you want to play again!)

How do you measure 4 liters of water if you have a 7-liter and a 5-liter bucket?
To measure 4 liters of water using a 7-liter and a 5-liter bucket, you can follow these steps: Fill the 5-liter bucket to the top and pour it into the 7-liter bucket, leaving 2 liters in the 5-liter bucket. Empty the 7-liter bucket and pour the remaining 2 liters from the 5-liter bucket into the 7-liter bucket. Fill the 5-liter bucket again and pour it into the 7-liter bucket, which already has 2 liters, making it a total of 4 liters in the 7-liter bucket.
