Two processes, p$1$ and p$2,$ arrive at time $0$ and start executing using MLF scheduling with $5$ priority levels.

The total CPU time of p$1$ is $60$ time units, and p$2$ is $10.$

The quantum is Q $=10$ at level $5$ and is doubled at each lower level.

The context switching time is S $=0.$ p$1$ terminates at priority level

p$2$ terminates at priority level

The turnaround time of p$1$ is

The turnaround time of p$2$ is

The average turnaround time, ATT, is
