In a demand paging memory system, page table is held in registers. The time taken to service a page fault is $8$ m.sec. if an empty frame is available or if the replaced page is not modified, and it takes $20$ m.secs., if the replaced page is modified. What is the average access time to service ... to be replaced is modified $70$% of the time ? $11.6$ m.sec. $16.4$ m.sec. $28$ m.sec. $14$ m.sec.

For the implementation of a paging scheme, suppose the average process size be $x$ bytes, the page size be $y$ bytes, and each page entry requires $z$ bytes. The optimum page size that minimizes the total overhead due to the page table and the internal fragmentation loss is given by $\frac{x}{2}$ $\frac{xz}{2}$ $\sqrt{2xz}$ $\frac{\sqrt{xz}}{2}$
