GATE 1996
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
(a) 10
(b) 4
(c) 8
(d) 9
So completion time of ‘A’ is 9.
