Turn Around Time = Process Completion Time – Process Arrival Time
Waiting time = Turn Around time – Burst time

| Process | Arrival Time | Burst Time | Completion Time | Turn Around Time | Waiting Time |
|---|---|---|---|---|---|

calculate the average waiting time & average turn-around time

Average turn-around time
= (6+7+11+16+13)/5
= 53/5
= 10.6
Average turn-around time = 10.6
Average waiting time
= (0+5+6+10+12)/5
=(33)/5
=6.6
Average waiting time =6.6
