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 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 _____ μs. (up to 2 decimal)
