Answer 1

First, take milk in 3 litre can, 3 times,9 litres of milk will be measured. Then the milkman will be left with 1 litre of milk, keep it aside. Now take 9 litres of milk and put it in 7 litres can. 7 litres of milk will be measured and 2 litres of milk will remain. Now take the 7 litres of milk and put it in the 3 litre can, 3 litres of milk will be measured and 4 litres will remain.  

  Now take that 4 litres of milk and add it with 1 litre of milk.

  Then the milkman will get 5 litres of milk
