Where is the father?

[ziad1985]

I don't know if this been around before, but here it goes...

Right now, the mum is 21 years older than the child.In 6 years, the mum will be 5 times as old as the child.


Question :
Where’s the father right now?

Solution:

The mum 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, it’ll be born in 9 months.
So right now, the father is on top of the mother

You're definitely making a big assumption saying that the father is on top. Some women are very controlling.
