Solution :

Geeta (MOM =M) is 21 years older than Raju (Child = C).
M = C + 21

In 6 years from now, Mom will be 5 times as old as her Child.

M + 6 = ( C + 6 ) x 5
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, -9 months
Child will be born in 9 months
So, right now, geeta's Husband is...
