Fill the 3 gal jug and pour all of it into the 5 gal jug. This leaves room for 2 more gal in 5 gal jug. Fill 3 gal jug again and top off the 5 gal jug. This will take exactly 2 gal to fill leaving 1 gal. Empty the 5 gal jug and pour the 1 gal from the 3 gal jug into the 5 gal jug. Then fill 3 gal jug and add it to the 1 gal that makes 4 gallons exactly in the 5 gal jug
