Answer:

If your milk contains 5% or less then  5%of  water, it  means, it is no longer milk. It is extremely condensed milk or powdered milk. Pure Milk contains about 87% water. When you reach 3–5% water, it is most likely in the powdered form. Any addition of purified milk will increase the water content immediately.

If you are talking about milk adulterated with 5% water, adding more milk to it to reduce this does not make sense. Boiling off the water does. Just 10 L milk contains 0.05*10 L water = 0.5 L water AND 9.7 L of    pure milk  .

EXPLANATION

20% water i.e. 0.2 L water is contained in (10 - 0.2)L = 9.8 L pure milk  

So (9.8 - 9.5) L = 0.3 L pure milk should be added.  

Answer is 0.3 L OR 300 ml pure milk boil the milk till you have 9.7 liters remaining..........

Hope this helps you......
