Maths Problem - Calling all Geniuses :D

Calling all maths geniuses out there .............





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





-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...
 
if the father is me then he's either under or behind the mother, definitely not on top.
