Such entertainment problems you must solve MENTALLY (it is the reason why people invent them and why
this problem was offered to you !) :


    The difference in ages is 18 years.


    In order for the older was 4 times age the younger, the younger's age must be one third of 18 years, i.e. 6 years.


    Answer.  It happened when Ashley was 6 years old and Cesar was 24 years old - exactly 24 years ago.
