Question

Aruns father is three times as old as arun if the sum of their ages is 56 years what are their ages

Answer 1

let arun's age be x
arun's father's age=3x
x+3x=4x
4x=56
x=56/4=28
arun age=28
father age=3x=3*28=84.

Answer 2

Let Arun's age be x.
Then his father's age= 3x
Sum of their ages= 3x+x= 4x
But given sum=56
=> 4x= 56
=> x= 56/4= 14
.: Arun's age is 14 years.
His father's age is 3x14= 42 years.
