First fill 5 litre and pour it into 7 Litre. Then again fill 5 litre and pour to 7 litre. Now 3 litres are left in 5 litre container. Empty 7 litre and pour 3 litre in it. Again fill 5 litre and pour in 7 litre. Now 7 litre is full and 1 liter left in 5 liter container. Empty 7 litre and pour 1 litre which is left in 5 litre container. Now 1 litre is already in 7 litre container, now fill 5 litre and pour into 7 litre container. now it is 6 litre in 7 litre container. DONE!
Several ways to achieve this - here is one solution. Fill the 5 litre container and pour it all into the 9 litre container. Fill the 5 litre container and pour it into the 9 litre container until the latter is full - leaving 1 litre in the 5 litre container. Empty the 9 litre container. Fill the 3 litre container and empty into 9 litre container. Repeat. There are now 6 litres in the 9 litre container. Pour the 1 litre from the 5 litre container into the 9 litre container which now contains 7 litres.
There are two easy ways to do these with these resources: The first one is to simply fill the two litre bucket half full and fill the four litre bucket to the brim and then, all together, in both buckets you have five litres: Voila The second one is slightly more complex you fill the four litre bucket three quatre full and then fill the other bucket to the brim: Voila As well as these there are many more more complex answers to this questions
There is most likely a more efficient way to do this, but this is the best I can do for now.Notation: ( x , y ) where x is the amount of water in the 5-liter container and y is the amount of water in the 7-liter container1. Fill the five-liter container ( 5 , 0 )2. Pour the five-liter container into the seven-liter container ( 0 , 5 )3. Fill the five-liter container ( 5 , 5 )4. Fill the seven-liter container with the five-liter container, leaving 3 liters in the five-liter container ( 3 , 7 )5. Pour out the seven-liter container ( 3 , 0 )6. Pour the five-liter container into the seven-liter container ( 0 , 3 )7. Fill the five-liter container ( 5 , 3 )8. Fill the seven-liter container with the five-liter container, leaving 1 liter in the five-liter container ( 1 , 7 )9. Pour out the seven-liter container ( 1 , 0 )10. Pour the five-liter container into the seven-liter container ( 0 , 1 )11. Fill the five-liter container ( 5 , 1 )12. Pour the five-liter container into the seven-liter container ( 0 , 6 )

8 times (which is 4.8 litres)
4=10-6=5x2-3x2 Pour twice the 5l container then take twice with the 3l container from it
five bottles. You'll also have at least 250ml left over to fill from a sixth bottle, and given that a 750ml wine bottle won't be completely full, you can estimate that actually about half (375ml) the sixth bottle can be poured into the 4l vat or container, given an average of 725ml in a 750m bottle (allowing for corks and margins of error.

It's the same puzzle from Die Hard 3, except you have to do it twice. First, use the eight liter jar to fill the three liter and dump it into the five liter. Now fill the three liter again and use it to fill the five liter up to the top. This leaves one liter in the three liter jar. Empty the five liter back into the eight and then dump the remaining milk in the three liter jar into the five liter. Fill the three liter again and dump it into the five liter. Now you have four liters in the five liter jar, and four liters are left in the eight liter jar.
First fill 5 litre and pour it into 7 Litre. Then again fill 5 litre and pour to 7 litre. Now 3 litres are left in 5 litre container. Empty 7 litre and pour 3 litre in it. Again fill 5 litre and pour in 7 litre. Now 7 litre is full and 1 liter left in 5 liter container. Empty 7 litre and pour 1 litre which is left in 5 litre container. Now 1 litre is already in 7 litre container, now fill 5 litre and pour into 7 litre container. now it is 6 litre in 7 litre container. DONE!
fill three liter can to the top empty contents into five liter can fill three liter can again empty into five liter can leaving one liter in the three liter can empty five liter can pour the remaining liter from three liter can into five liter can fill three liter can again and empty into five liter can leaving exactly 4 liters
Notation: ( x , y ) where x is the amount of water in the 3-gallon container and y is the amount of water in the 5-gallon container1. Fill the three-gallon container ( 3 , 0 )2. Pour the three gallons into the 5-gallon container ( 0 , 3 )3. Fill the three-gallon container ( 3 , 3 )4. Fill the five-gallon container with the three-gallon container, leaving 1 gallon in the three gallon container ( 1 , 5 )5. Pour out the water from the five-gallon container ( 1 , 0 )6. Pour the water from the three-gallon container into the five-gallon container ( 0 , 1 )7. Fill the three-gallon container ( 3 , 1 )8. Pour the water from the three-gallon container into the five-gallon container ( 0 , 4 )Another great answer here:[See below for the related link]
