Extracted text: The amount of memory on a system is inversely proportional to the page fault rate. Each time when memory doubles that page fault rate is reduced by thrice. (i.e. P is made P/3). Currently, the system has 32MB memory and the page fault rate is 2%. The main memory access time is 500ns, and effective memory access time 300us. if memory is increased by 128 MB then Effective memory access time is (up to 2 decimal) µs.
