Consider a two-level hierarchy L1 (Cache) has an accessing time of 10 nsec and main memory has accessing time of 100 nsec. Assume the hit ratio read operation is 0.75 and 40% reference are for the write operation. The average access time for the system (in nsec) if it uses write through technique is?

I am getting 61 but the answer given is 67.6. please confirm the answer.

ME Test series question
A computer uses two level cache L1 and L2 and in 2000 memory references there are 320 misses in L1 cache and 150 misses in L2lcache. If the miss penalty of L2 is 300 clock cycles, hit time of L1 is 1 clock cycle and hit time of L2 is 10 clock cycles what is the average memory access time?
