0 0 votes please explain how hit ratio of L2 is taken as 0.5? instead of 0.9 as 10 misses are mentioned is it like as 20 misses at levle 1 out of which only 10 missed at level 2, so 10 out of 20 (and not 100) hence 0.5?

Since L1 has twenty misses and out of that twenty misses, 10 are misses for L2. 1 1 replyShare balchandar reddy san commented Dec 21, 2018 reply Follow flag btw, the answer given is wrong it has to 36/7 as the value of x is 18/7 0 0 replyShare Please log in or register to add a comment.
