But here it ask.... Minimum avg response time.. Not waiting time..

how r u telling this? What is meaning of expected runtime?

Since time quantum is not given.... Wat happen if we take large time quantum.... Den which has minm response time???

Answer 1

we can't support to RR bcz if time quantum is too large then it work as FCFS..and here time quantum is not given.in this case SJF will give best result.
