Suppose there are $3$ jobs A, B and C arrive at approximately at the same time. But job A arrives slightly earlier than job B, and job B arrives alightly earlier than job C. Job A requires $2$ sec of CPU, Job B requires $8$ sec and job C requires $7$ sec. Assume time slice is of $1$ sec. Given Round Robin scheduler, what is the turn around time of job B?
