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 i have solved

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
