operating system solve it please in 20 min maximum please , be fast please , I will give u a like

Suppose you have the following processes Process Arrival Time P1 P2 2 3 P4 S PS 7 P3 Burst Time 14 10 2 7 13 Use the following multilevel feedback queue CPU scheduling algorithm to execute the above processes Queue 1: using RR CPU scheduling algorithm with Q = 4 ms. Queue 2: using RR CPU scheduling algorithm with Q = 6 ms, and Queue 3: using FCFS CPU scheduling algorithm FOFS 1. Draw the Gantt Chart for Queue 2 2. Find the total waiting time for process P2. Hint 1: Once a process executed using one queue it should go direct to start execution in the next queue if this queue is free Hint 2: The starting time is 0 for Queue 1 only and it is different in all remaining queues
