Q) Consider a three-level memory system, where the access time for the cache is 100 nanoseconds, main memory access time is 1200 nanoseconds, and disk access time is 15 ms. Main memory hit ratio is estimated to be 70%. What is the cache hit ratio H, if the average access time is required to be 50% greater than the cache access time? State any assumptions you see necessary.
