**28 minutes**. Ask a Question.

I just read the "Where ist the fish?" topic? This reminds me of another one named "Where is the father"? Maybe some of you already know this one. I guess it is quite famous, at least in Germany it is. You can try to solve it. And it definetely works - you can give an adequate solution to this problem. If no one is able to solve it, I will give the answer later on.

This is one of those questions I like most......

There is a mother which is 21 years older than her son.

In 6 years, the son will be 5 times younger than the mother. ( <-- btw., is this correctly translated into English? )

Question: Where is the father?

Hi Case Assigner,

well, where is the father? What about the son? And the mother? And what are they doing? Heh... hehehe, let's see:

Now:

So the son is -3/4 years old, that is, minus nine month old. He will... be born? What's the future of "was born"? Umm, let's then say he'll "come out" in nine months. You asked, where is the father... how should I know? I don't even know exactly where the son is!

well, where is the father? What about the son? And the mother? And what are they doing? Heh... hehehe, let's see:

a

_{m}= a_{s}+ 21 (age of mother = age of son plus 21)a

_{m6}= 5a_{s6}(age of mother after 6 years = 5 times the age of the son after 6 years)Now:

a

_{m6}= 5a_{s6}a_{m }+ 6 = 5(a_{s}+ 6)a

_{s}+ 21 + 6 = 5(a_{s}+ 6)a

_{s }=**-3/4 (son's age)**a

_{m}= a_{s}+ 21 =**20+1/4 (mother's age)**So the son is -3/4 years old, that is, minus nine month old. He will... be born? What's the future of "was born"? Umm, let's then say he'll "come out" in nine months. You asked, where is the father... how should I know? I don't even know exactly where the son is!

Well, since it takes 9 months to carry a baby, I would say the father is, at that moment, impregnating the mother. Although babies do come at their own pace, so it seems a little silly to predict exactly when he'll be born.
