.
Mental solution:

1.  A is 5 years older than R,

         and this age difference will be always in place.


2.  Four years later A will be twice as old as R.

         Hence, four years later A will be twice as old as R  AND  (according to n.1) A will be 5 years older than R, at the same time.


         It means that 4 years later A will be 10 years old, while R will be 5 years old.


3.  Hence, their present age is  A= 6,  R = 1.

Solved.
