Solution :


The mom is 21 years older than the child.


M = C + 21


In 6 years from now the mom 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 = -9 months


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!
