Assume that the following jobs are to be executed on a single processor system. All jobs have arrived at 0 msec.
If scheduling is round robin with time slice 1 msec, then what is the completion time for job ‘a’?

Figure for question 6

Correct answer: B

Explanation

Round robin (1 ms): a→0-1, b→1-2 (done), c→2-3, d→3-4, a→4-5, c→5-6, d→6-7 (done), a→7-8, c→8-9, a→9-10. Job 'a' (4 ms) completes at 10 ms.
