Where is Father? Mathematical Question.

Saw this on a friend's facebook wall.
Just have to share. It's LOL.
(something in between while I blog about the third part of the surprise)


A mother is 21 years older than the child.
6 years from now the mother will be 5 times as old as the child.

Question: Where's the father?



(Give 10 minutes to think about it before scrolling down)

Got it?


The answer is...


The mother is 21 years older than the child.
M = C + 21

In 6 years from now the mum will be 5 times as old as the child.
M + 6 = (C + 6) x 5... See More

Hence,
C + 21 + 6 = (C + 6) x 5
C + 27 = 5C + 30
-3 = 4C
C = -3/4

The child is -3/4 years old, that is, it'll be born in 9 months.


Thus... by mathematical deduction,
Right now, the father is on top of the mother.
