nano0101,

please think practically

in your prevoius answer you said :  Again repeat step 1 n pour to 10 pint jug 1
but you cannot do this because for doing this, first you need to remove the lemonade from the 4 pint jug.   where will you remove it ? nethier you can throw it nor you have any other container.

 

please read my question very carefully as it is not as simple as it looks.
