Answer 1

$\huge\sf\underline{Answer}$

The age of Vijay is 10 years.

The age of Vijay's Father is 40 years.

And the age of Vijay's Grandfather is 65 years.

Explanation:-

Let the age of Vijay be x years

As it is given, that Vijay's father is 25 years younger than his grandfather and 30 years older than Vijay. Therefore:-

The age of Vijay's Father = (x + 30) years

And the age of Vijay => (x + 30 + 25) years = (x + 55) years

The sum of their ages is 115.

According to the question,

=> x + (x + 30) + (x + 55) = 115

=> x + x + 30 + x + 55 = 115

=> 3x + 85 = 115

=> 3x = 115 - 85

=> 3x = 30

=> x = 30/3

=> x = 10

Hence, the age of Vijay is 10 years.

His father's age is => (x + 30) = (10 + 30) = 40 years

And his Grandfather's age => (x + 55) = (10 + 55) = 65 years
