1.Since n is not given...so throughput will be 1/pipeline cycle time
which is 1/10 (M-1) and 1/7.5(M-2)...Hence M2 is always faster than M1
2.Latency is after how much time new i/p is given to system which is pipeline cycle time
For M-1 Tp=10 and for M-2 Tp=7.5 Hence M-2 has shorter latency
3.Consider n=1 M1<M2 so not always true
