Answer 1

Solution :

Kiran's father's present age is three times that of Kiran's age and his grandfather's age is 20 years more than Kiran's father's age.

We are given that the age of Kiran is x. Then we have to find the age of kiran'a grandfather in terms of x.

If Kiran's age is x years

Kiran's father's age is three times his age.

So, the age of Kiran's father should be 3x years.

Now, the age of Kiran's grandfather is 20 years more than that of his father's

So, his grandfather 'a age becomes 3x + 20 years.

From the options given above, we can see that option C is the correct answer.
