[Computer Science] Q. Suppose there are 8 processes in a system which are waiting to be assigned to the ready queue. The processes have the following properties. Process P1 has burst time 15, priority 6 Process P2 has burst time 12, priority 4 Process P3 has burst time 6, priority 12 Process P4 has burst time 5, priority 11 Process P5 has burst time 8, priority 9 Process P6 has burst time 9, priority 2 Process P7 has burst time 2, priority 20 Process P8 has burst time 17, priority 6 You have to use Multilevel Feedback Queue. It has three queues. The first queue takes processes with priority value from 1 to 5, the second queue takes processes with priority value of 6 to 10 and rest of the processes go to the third queue. First queue follows Round Robin Scheduling with time quantum= 4 Second queue follows Round Robin Scheduling with time quantum = 6 Third queue follows FCFC scheduling. Draw the gantt chart and calculate the average waiting time
