Question

Rohan is 26 yrs younger to his father.The father is 20yrs younger to rohan grandfather.If sum of thre is 84, what is the age of father?

Answer 1

LET THE Grandmother's age be x

$x + x - 20 + x - 20 - 26 = 84\\ 3x - 66 = 84 \\ 3x = 84 + 66 \\ 3x = 150\\ x = 50$

FATHER's AGE - x-20
- 50-20
- 30

Hence , father's age is 30 Yrs.

Answer 2

let the Rohan's age be x
His father age =x+26
His grandfathers age=x+26+20
By question
x+x+26+x+26+20=84
3x+72=84
3x=84-72
3x=12
x=12/3
x=4
Therefore,his father age =30
