Answer 2

Let the age of Monu = x years
Given that Monu's father is 29 years older than Monu.
Therefore
Monu's father age = x + 29 years
Also given that Monu's grandfather is 26 years older than Monu's father
Therefore
Monu' grandfather age = Monu's father age + 26 years
                                        =  x + 29 + 26
                                        =  x + 55 years

Also given that the sum of their ages = 135
Therefore
x + x + 29 + x + 55 = 135
3x + 84 = 135
3x = 135 - 84
x = 51/3
x = 17 years

The age of Monu = x years = 17 years
The age of Monu's father = x + 29 = 46 years
The age of Monu's grandfather = x + 55 = 72 years.
