(b) The average CPI for L1, L2 and L3 cache system with no miss is 1.0. L3 has a hit rate of 85%. L1 has a miss rate of 85% and L2 has a hit rate of R%. 1 cycle takes 0.45 ns. The miss penalty for L1 is 6 cycles, for L2 is 16 cycles and for L3 is 56 cycles. If the cache average access time is found to be 1.2 ns, evaluate the miss rate of the L2 cache.

Question
The average CPI for L1, L2 and L3 cache system with no miss is 1.0. L3 has a hit rate of 85%. L1 has a miss rate of 85% and L2 has a hit rate of R%. 1 cycle takes 0.45 ns. The miss penalty for L1 is 6 cycles, for L2 is 16 cycles and for L3 is 56 cycles. If the cache average access time is found to be 1.2 ns, evaluate the miss (b) rate of the L2 cache.
