Two friends meet on the street. They have not seen each other for many years. They talk about various things and then one of them says, "I heard that business managers are intelligent guys. Since you are a business manager, I’d like to give you a problem to solve. You know, today is a very special day for me. All three of my sons celebrate their birthday this very day! Can you tell me how old each of them is?""Sure," answers the business manager, "but you will have to tell me something about them.""OK, I’ll give you some hints," replies the father of the three sons, "The product of the ages of my sons is 36.""That is fine," says the manager, "but I’ll need more than just this."The father looks around. "The sum of their ages is equal to the windows in that building." Says the father pointing at a building next to them. The manager count the windows and replies, "Still, I need an additional hint to solve your puzzle.""My oldest son has blue eyes." Says the father."Oh, this is sufficient!" exclaims the manager, and he give the father the correct the ages of his three sons. What Are the Ages of the 3 sons?
