Let's say in a system, it takes 8 milliseconds to service a page fault if an empty page is available or the replaced page is not modified, and 20 milliseconds if the page to be replaced is modified. Memory access time is 100 nanoseconds. Assume that the page to be replaced is modified 70 percent of the time The maximum acceptable page-fault rate for an effective access time of no more than 200 nanoseconds is:
