riya is 21 years older than her son Raju. In 6 years from now, riya will be 5 times as old as Raju.
Question : Where is riya’s husband?
(There is a mathematical solution for this. Try it before scrolling down)
Priya (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, riya’s Husband is..
