Fill the 5 gallon jug Pour from the 5 gallon to fill the 3 gallon jug You now have 2 gallons in the 5 gallon jug Empty the 3 gallon jug Pour the 2 gallons from the 5 gallon jug into the 3 gallon jug Fill the 5 gallon jug Pour from the 5 gallon jug to fill the three gallon jug -- this will tale 1 gallon You now have 4 gallons in the 5 gallon jug
Fill the 5 gallon jug completely then pour that into the 3 gallon jug. Empty out the 3 gallon jug and pour the remaining water in the 5 gallon jug into the 3 gallon jug. Then just fill up the 5 gal jug again you will have 2 gallons in the 3 gallon jug and 5 gallons in the 5 gallon jug.
There are lots of ways to do this, but here's one: Fill the 5 gallon jug to the top. Pour the water from the 5 gallon jug to the 3 gallon jug until the 3 gallon jug is full. What's left in the 5 gallon jug is 5 - 3 = 2 gallons. Dump what's in the 3 gallon jug. Put the 2 gallons from the larger jug into the smaller jug. Now fill the 5 gallon jug. You'll have 5 + 2 = 7 gallons, as needed.
Fill the 5L jug. Pour into 3L jug so that it is full and 2L remain in the 5L jug. Empty the 3L jug and then pour 2L from the 5L jug into the 3L jug. Fill the 5L jug again. So now you have 5L in the 5L jug and 2L in the 3L jug. Total of 7L.
The answer depends on how big the jug is.
