Each process is assigned a numerical priority, with a higher number indicating a higher relative priority. For processes with the same priority, a round-robin scheduler will be used with a time quantum of 10 units. If a process is preempted by a higher-priority process, the preempted process is placed at the end of the queue. a.What is the turnaround time for P3? Give your answer as an integer. b.
