ANSWER

First the man takes an empty vessel.  

He takes out 9 litres of milk from 10 litre can using 3 litre can. This he pours to the empty vessel. Now 1 litre of milk remains in the 10 litre can. Using 7 litre can he takes out 7 litre of milk from the vessel and pours it to the 10 litre can. Now the 10 litre can will have 1 + 7 = 8 litres of milk. Again using 3 litre can, he takes 3 litres milk from 10 litre can. Now the 10 litre can will be 8 – 3 = 5 litres of milk.

So he gives 5 litres of milk to the customer
