page are fitted in frames ,so first we need to determine the pages but given request are just the record request in decimal.we can assume that first page to address from 0000 to 0099 and page 2 contains records from 0100 to 0199 and so on(it is given in question that each page contains 100 records) and so on.sso page reqquest string is 01,02,04,04,05,05,05,01,02,02,02,03,03 clearly 7 page fault.
