Let the elder son’s age be x
So fathers age= 2x
Now, after 10 years,
Age of elder son= x+10
And age of father= 2x+10
Also, younger son= (2x+10)/3
According to the question,
x+10-(2x+10/3)= 15
(3x+30-2x-10)/3= 15
x+20=45
x= 25
so, present age of father= 50 years
So fathers age= 2x
Now, after 10 years,
Age of elder son= x+10
And age of father= 2x+10
Also, younger son= (2x+10)/3
According to the question,
x+10-(2x+10/3)= 15
(3x+30-2x-10)/3= 15
x+20=45
x= 25
so, present age of father= 50 years
