Blue eyes
Yesterday I met a colleague of mine. I know he has three sons and I asked him their age.
He answered: “The product of their ages makes 36”.
I thought: “These mathematicians are crazy!”.
Then I said: “That’s simply not enough! How can I
tell their age? Tell me something more”.
He said: “You smart guy! Well, the sum of their ages makes the number of windows you can see in
that house over there”.
I thought: “These mathematicians are really crazy!”. Then I counted the windows, I thought five
minutes and said: “I cannot tell their age! Tell me something more”.
He laughed at me and said: “You are really a smart guy! Well, my eldest son has got blue eyes”.
Then I said: “I got it!” and I gave him the correct answer.
Well, what is the correct answer?
Hints
#First of all, it’s not a joke; it’s a serious problem. There is no advanced mathematics involved.
#However, in my opinion it’s a rather difficult problem; but the solution is nice!
#One more thing: sometimes the information is not where you think it is; that’s exactly what this problem is about. And another thing: don’t ask, I will not tell you how many those windows were…
