Fill up the 7 gallon jug completely. Now pour as much of the 7 gallons as you can into the 4 gallon jug. You should have 3 gallons in the 7 gallon jug. Dump out the 4 gallon jug, pour the 3 gallons from the 7 gallon jug into the 4 gallon container. Finally, fill up the 7 gallon jug completely and pour what you can, 1 gallon, into the 4 gallon jug until it is full. Taking 1 gallon from seven gallons leaves 6 gallons.

pour water in 7 ltr gallon ,and pour that 7 ltr water in 4 ltr gallon so remaining 3 will be there in 7 ltr gallon, pour out the 4 ltr water and again pour back those remaining 3 ltr to 4 ltr gallon, now pour again 7 ltr water in 7 ltr gallon. last pour 7 ltr water to 4 ltr gallon. In 4 ltr gallon only one more ltr left out so now 7 ltr becomes 6 ltr.
