let the ages of two sons be X
and father age be Y
then
according to question
=》3 (X)=Y----------eq 1
x=y/3
then
2(X+10)=Y+5 {we take here x+10 because it is the age of two sons so 5×2=10}
=》 2x +20=Y+5
=》 2x -y+15=0 -------eq 2
by eq 1 and eq 2
2y/3-y+15=0
multiplying eq by 3
2y-3y+45=0
-y=-45
y=45
so age of father is 45

Answer:let the sum of his two son's age = x

then,father become =3x


5 year later age of son= x+5

and father = 3x+5

3x+5=2 (x+5)

3x+5=2x+10

3x-2x=10-5

x=5


sum of sons age =5

fathers age =15
