You are getting confused with the location in the RAM array and the page frame in the RAM.

Page tables print which page frame the process page is in, NOT the array index the page starts at.

From the project description: "We have a computer whose RAM is an array of size 16. It is an array of pointers. There are 8 page frames in the RAM, each consisting of two contiguous locations in the array. Hence, the page size of this computer is 2. ... Each process has a page table, which is an integer array, entry of a process page table indicates whether the page is in RAM or in the virtual memory (on disc), k if the page is in RAM (k is the frame number, between 0 . . . 7), and 99 if the page is in disc (99 cannot be a frame number).
