.

Let F be the Fred's age,
    Then his son's present age is (F-25).


When Fred was at his son's age ?  - 25 years ago.

At that time Fred was (F-25) years and his son was  ((F-25)-25 = (F-50) years old.


The condition says

F- 25 = 2*(F-50).  ====>

F = 75.


Answer.  Fred is 75 years old now.  His son is 50 years old.
