Lets say G, F and S are ages of grand father, father and son in years

than

G+F+S = 140

S*12 = G

S*365 = (F*365)/7 => F = 7S

Than 12S + 7S + s = 140 => 20S = 140 => S = 7 Years

F = 49 Years

G = 84 Years

than

G+F+S = 140

S*12 = G

S*365 = (F*365)/7 => F = 7S

Than 12S + 7S + s = 140 => 20S = 140 => S = 7 Years

F = 49 Years

G = 84 Years
