For better calculation, considering all months is of 30 days , 
1 year = 360 days

Let Dada age be D days 
Baap age be B days 
Pota age be P days
A/q,
D + B +P = 110 ×360 days
now, Dada age in year = Pota age in months
so, D = 12 P
now, Baap age in week = Pota age in days
so, B = 7 P
now , from first equation,
D + B +P = 110 ×360 days
⇒12P + 7P +P = 110× 360
⇒20 P = 110 ×360
⇒P = 1980 days 
       = 1980/360 = 5.5 years
so, B = 7×P = 7×5.5 = 38.5 years
and , D = 12 P = 12× 5.5 = 66 years 
so, Pota = 5.5 years
      Baap = 38.5 years
      Dada = 66 years

Hope this will help you :)
