IF-2015: How shall I number the pages?

The Guide for Applicants specifies the following: The page count begins after the 'List of Participants' and ends before the 'CV of the experienced researcher' (the CV itself has a page limit of 5 pages). Section 1 to 3 should not have more than 10 pages, as evaluators are asked to disregard any content beyond the 10 pages. 
You can choose to locate the page numbers anywhere in the bottom of the page (left, right or in the middle). It is typical to put them in the bottom right-hand corner. You can use either latin (I, II, III,...) or modern Arabic (1, 2, 3,...) numerals, as long as the numbers are consecutive. The Guide for Applicants recommends the format “Part B – Page X of Y".
