John pointed me that one third of the year is 4 months.

First,  I am very glad that John returned back to the forum (!)

Second,  the months are of  UNEQUAL  time length,  so it has no much sense to say that one third of the year is  4  months.

It depends on which  month / (what months)  and which year.


My diagnosis remains the same:  if in  "age word problem"  the answer is not an integer,
then such a problem is  DEFECTIVE  by the definition.
