Four jobs to be executed on a single processor system arrive at time 0 in the order A, B, C, D . Their burst CPU time requirements are 4, 1, 8, 1 time units respectively. The completion time of A under round robin scheduling with time slice of one time unit is
Explanation: The order of execution of the processes with the arrival time of each process = 0, using round robin algorithm with time quanta = 1
A B C D A C A C A, i.e, after 8 context switches, A finally completes it execution
So, the correct option is (D).
