Where's daddy?

[VAXman(Admin)]

Here's some fun for you moonies... a little math problem:

Question :

The mother is 21 years older than the child.

In 6 years from now the mother will be 5 times as old as the child.

Where's the father?

When/if you get the answer, PM me.

Driving nuts too!

OK. Enough of you responded and most with the correct answer.


A little simple algebra is needed.

First: The mother (M) is (=) 21 years older (+) than the Child (C).

M = 21 + C

Second: In 6 years from now the mother (M +6) will be (=) 5 times (5*) as old as the child {6 years from now} (C + 6).

M + 6 = 5 * (C + 6)

We now have a system of linear equations which can be solved in a number of different ways. The simplest is by substitution. Substitute the relation ship of Mother to Child's age in the First equation into the second:

(21 + C) +6 = 5 * (C +6) :: 27 + C = 5C + 30

Now collecting the like terms yeilds:

C - 5C = 30 - 27 :: -4C = 3

C (the child's age) = -3/4 (years)

This is 9 months before the child is born, so it must be the moment of conception. The whereabouts of the father are now left as an exercise for the reader.


Just trying to keep your math skills fresh and your minds dirty!

Ouch... math hurt brain. Me pound drum instead.....

No Rick she was 21 years older. I'd guess that "daddy" was giving her one hell of a 21st birthday present!

And I mentally managed to get the child's age to -1.8 years , which is indeed possible for the african elephant, so I figured daddy was in Africa. Lol, should never use my head unnecessarily...

Btw, no need for an eq. system really as six years from now, if child then is c years, mother will be 5c years. Since the difference remains, 5c - c = 21 years, i.e. the child is then c = 21/4 = 5.25 years, which translates to -0.75 years now.

VAXman, thanks for twisting our brains Hoping for followers. I might have something in a drawer somewhere...
