Let a, b & c be the ages of grandson, father & grandfather respectively.
Given that sum of their ages is 100 years
⇒ a+b+c = 100 ... (1)
Also, Age of grandson in months = Age of grandfather in years
⇒ a*12 = c ...(2)
& age of grandson in days = Age of father in weeks
⇒ a*365 = (b*365)/7
⇒ 7a = b ...(3)
substituting the values of b and c from (2) & (3) in equation (1), we get
a+7a+12a = 100
⇒20 a = 100
⇒ a = 5( Age of granson = 5 years)
therefore, b = 7a = 7*5 = 35 (Age of father = 35 years)
& c = 12a = 12*5 = 60(Age of grandfather = 60 years)
