(#M40154344) AMCAT QUESTION Operating system Keep an EYE

There are 5 process P1, P2. P3, P4 and P5 to be irocessed.


Process
Arrival Priority Burst Time(in
Time milliseconds)

P1 0 2 10
P2 0 5 2
P3 2 4 1
P4 2 1 2
P5 3 3 3

Here lower number in the priority column in the given image denotes the higher priority.


Calculate the average waiting time, if the processes are first processed by the preemptive priority scheduling untill all processes arrive in the system and when all the processes have arrived, then the processes will be scheduled by non-preemptive Shortest Job First(SJF) scheduling.
