The final Gantt. chart is shown in the figure above.

Completion time = Time at which process completes execution.

Turnaround Time =Completion Time - Arrival Time

Using the final gantt. chart and definition of Turnaround Time, we generate the following table :

Process CPU Burst time Arrival time Completion time Turnaround Time

P1 30 10 80 70

P2 20 17 85 68

P3 15 21 55 34

P4 10 27 65 38
