Second Scientist asked for their ages.First Scientist replied the product of their ages is 36 and the sum of their ages is equal to your house number.Second Scientist thought for a while and requested him to give one more hint as the information was not sufficient for guessing the correct ages of the three daughters.First Scientist gives him the last clue that ''My eldest daughter has blue eyes''.Immediately,the Second Scientist could tell him his daughters' ages.
