Calling all maths geniuses to try this...
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?

Try first, before you check the answer below.

Solution :
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

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

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

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

Why can't he be underneath the mother or behind her?
