From the question we can simplify as

1. Sum of the age of all three is 140
2. Grandfather age is 12 times of Grandson
3. Father age is 7 times of Grandson

Now let assume grandfather age is x, fathers is y and grandson is z.Then we have following equations
x + y + z = 140
x =12z
y = 7z

Which gives 12z + 7z + z = 140
z = 7

So Age of Grandfather is 84
Age of Fathers is 49
Age Grandson is 7
