Answer of this Quiz:Grand Father, Father and Grand Son

Son’s age: 7 Years, Father Age: 49 Years and Grand Father’s Age: 84 Years. 

Lets assume the age(in years) of Grand Father, Father and Son as GF, F and S respectively.
Sum of their age is 140 Years
=> Equation 1 => GF + F + S = 140
Grand Son’s age in month = Grand Father’s age in years
S*12 = GF => Equation 2=> GF = 12S
Grand Son’s age in days = Father’s age in weeks
S*365 = F*(365/7)
S = F/7 => Equation 3 => F = 7S

Now we have three variables and three equations, we can easily solve it
12S + 7S + S = 140
20s= 140 => S = 7
F = 7S = 49
GF = 12S = 84.
