Solution:

Let present age of Vikas Prashant, \& Shubahm be x, y & z respectively
And Ratio of age of Shubham & Prashant

=100: 60=5: 3

y={3z}/5

....(i)
ATQ -

(x+6)+(y+6)=80

x+y=68

....(ii)

(x+16)+(z+16)=120

x+z=88

...(iii)

x+\;{3 z}/{5}=68

....(iv)
from (iii) & (iv) we get
x = 38 years & z = 50 years

y={3×50}/5

y = 30 years
Sum of age of Prashant, Shubahm & Vikas after four years

=30+38+50+4

=130

years
