As Unreality calculated, the child is -0.75 years old. I did this the easy way, though. If in 6 years the mother will be 21 years older than and 5 times as old as the child, then:
5*(X+6) = (X+6)+21
4*(X+6) = 21
X+6 = 5.25
X = -0.75
So, at present the child is three quarters of a year shy of being born.
Three quarters of a year is nine months.
Nine months is the average gestation period of a human.
Assuming a perfect pregnancy, Dad should be with Mom in a very intimate fashion right now.
Of course, children are not born exactly nine months after conception. So, right now might be several weeks before or after the exact moment of conception.
Still, I think that was the intent of the riddle. Go to the full post
