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?
well, where is the father? What about the son? And the mother? And what are they doing? Heh... hehehe, let's see:
am = as + 21 (age of mother = age of son plus 21)
am6 = 5as6 (age of mother after 6 years = 5 times the age of the son after 6 years)
am6 = 5as6
am + 6 = 5(as + 6)
as + 21 + 6 = 5(as + 6)
as = -3/4 (son's age)
am = as + 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!

Grammar GeekWell, 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.Yeah, it doesn't take exactly nine months, so you can't tell exactly where the son is... maybe he's still in the testicles, who knows... or maybe he's going to leave, and he's like "Ok dude, I'm outta here, see ya in nine months". That's why I said there's no exact answer actually.
