Question

Rohan is 26 years younger to his father. the father is 20 years younger to Rohan's grand father. If sym of the three is 84 years, what is the age of the father

Answer 1

Let the Rohan's grandfather age be x
So Rohan's father age = x-20
So Rohan age = x-20-26
x+x-20+x-20-26 = 84
3x - 66 = 84
3x = 84 + 66
3x = 150
x = 150/3
x = 50
Grandfather's age is x = 50
Father's age x-20 = 50-20 = 30

Answer 2

Let the father age be x.

So, Rohan age is x-26

and grandfather age is x+20

According to the question,

x+x+20+x-26=84

3x-6=84

3x=84+6

x=90/3

x(father)=30

Son=4

Grandfather=50
