@vijaycs don't we need page size too ?

Yes, page size should be given .

average amount of unused page space per process is internal fragmentation suffered by last page of the process which is P/2 where P is the page size .

If question want to take default page size, we take 4KB, then unused space is 2KB.

yes, thanks @Kapilp, @mcjoshi  :)
