Consider $5$ processes whose Arrival time and CPU Burst time is as follows $($Process no: Arrival time :

Burst time$)$:

$P1$ :$0,3$

$P2$ : $2,3$

$P3$ :$3,2$

$P4$ :$5,5$

$P5$ :$6,9$

Assume that the processes are scheduled using FCFS scheduling algorithm. The average waiting and turaround time is

$2\mathrm{.}5$ and $7\mathrm{.}0$

$2\mathrm{.}8$ and $7\mathrm{.}2$

$1\mathrm{.}9$ and $6\mathrm{.}9$

$2\mathrm{.}6$ and $7\mathrm{.}1$
