Answer 1

let the age of his son be X
show the age of his father equals to 3 x
according to question
3x+X=40
4x=40
X=10

and the age of his father =3x
=3*10=30

Answer 2

total sum of age of father and son= 40 years

age of son= x
age of father= 3x

sum of Ages=40
x+3x=40
4x=40
x=40÷4
=10

age of son= x= 10 years
Age of father= 3x= 3×10= 30 years

so, son is 10 years old and his father is 30 years old.
