Question 1804 – Nielit Scientist-B 17-12-2017

Consider the following four processes with their corresponding arrival time and burst time :

What is the average turnaround time (in ms) for these processes using FCFS scheduling algorithm ?

Correct Answer: B

Given, FCFS it means first come first serve. And also it is pure preemptive scheduling.

Average Turnaround Time =(8+13.4+14.2+15.6)/4=(51.2)/4=12.8
