$1,$ what is Average turnaround time and Average first$-$response time? Question $2.$ Consider the situation when right after C terminates $5$ more jobs arrive without any delay $($i$.$e$.,$ they all arrive at the same time at which C terminates$).$ Each of these new jobs are of length $5$ms$.$ When will A and B start running again? Question $3,$ Now assume:

The MLFQ is implemented with a priority boost.

The boosting is applied after every $15$ms$.$ So$,$ the first$-$boosting happens at t $=15,$ next one at t $=30,$ and so on$.$

We only boost from Q$3$ to Q$1.$ The boosted jobs in Q$1$ are in the same order as they were in Q$3$ and they are put at the end of the existing jobs in Q$1.$ All jobs are boosted instantaneously $($with no time lag$).$

When will A and B start start running again?qqQ
