Just have a look at it,.....it may happen that you get forced to think upon?
There are 3 jars.first of 8 liters,second of 5 liters,and third of 3 liters ...jar of 8 liters is full of milk, you have to separate the milk into 4-4 liters using the jars of 5&3 liters. i.e. jar of 8 liters and 5 liters should contain equal quantity of milk.i.e. 4-4..[U DONT HAVE ANY MEASUREMENT]
Fill 3 liter jar and pour in 5 Fill 3 liter jar again and fill 5 - you are left with 1litre in the 3 litre jar. Throw the 5 litres back into 8 litres. 5ltr jar is now empty. Pour the 1 litre from 3litre jar into 5. Fill 3 litres and throw into 5. Done. Another Way...
Fill 5 ltr jar and pour into 3. left with 2 litres in 5jar. Throw 3 ltr jar back into 8 litre jar. Pour the 2 litres from 5 ltr jar into 3ltr jar. Fill the 5 litres jar. Pour from the 5 liter jar into 3 ltr jar. left with 4 litres in 5 ltr jar. Throw the 3ltr jar back into 8 litre jar. Done.
