There are 3 volumes of an encyclopedia, each with the same number of pages, each listed $$consecutively$$. If the 5th pages of the 3 encyclopedias have a sum of $$1335$$, how many pages are in each encyclopedia?

(Hint: the $$5th$$ pages of the 3 encyclopedias are different, for example: the $$5th$$ page of the first encyclopedia would be page $$5$$, the second encyclopedia would have a different page number for page 5)
