![In a three level memory hierarchy, the access
time of cache, main and virtual memory is 5
nano-seconds, 100 nano-seconds and 10 milli-
seconds respectively. If the hit ratio is 80% for
the cache and 99.5% for the main memory, then
the closest average access time of memory
hierarchy in nano-seconds is:](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb72d5674-7d6b-4c26-82bf-e103ebd8e13e%2F0c516b54-16cb-459c-ae0b-39248d64ee5d%2Fmhyjm2r_processed.jpeg&w=3840&q=75)
