Consider a 5 stage pipeline with IF , ID, EX, WB and MA having latencies (in ms) 3,8,5,6,4. What is average CPI of non pipeline CPU when speed up achieved by to pipeline is 4?

I think answer is wrong 

For non pipe line total time =  Total number of instruction * (26) 

As they have directly given time , we don’t need to do “number of cycles * time for each cycle” calculation

For pipeline version total time = Total number of instruction * max(3,8,5,6,4)

So No role of CPI
