Question
proportional The amount of memory on a system is inversely 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 of memory and the page fault rate is 2%. The main memory access time is 500ns, and the effective memory access time is 300us. If memory is increased upto 128 MB then Effective memory access time is us. (up to 2 decimal)
