Assume that three jobs arrive at approximately the same time (arrival time are all 0), but Job A arrives slightly before Job B, and Job B arrives slightly before job C (if the jobs must be selected in order, the order should be A->B->C). Job A requires 3 sec of CPU, Job B is 5 secs, and Job C is 4 secs. Assume a time-slice of 1 second.

i. Given a RR scheduler, what is the average response time of the three jobs?

ii. Given an SJF scheduler, what is the turnaround time of job B?

iii. Given a FIFO scheduler, what is the turnaround time of job B?
