Applied Maths 4 Marks Question

Consider the available processes given below in the ready queue for execution and with given burst time.

a) What is the time at which all the processes get executed?
b) Find the average waiting time and average turnaround time using the non- pre-emptive SJF
scheduling algorithm.

Consider the available processes given below in the ready queue for execution and with given burst time.

a) What is the time at which all the processes get executed?
b) Find the average turnaround time using the non- pre-emptive FCFS scheduling algorithm

Consider the available processes given below in the ready queue for execution, with arrival time as 0 for
all and given burst time. Find the average waiting time using the SJF scheduling algorithm.

A boat covers 32 km upstream and 36 km downstream in 7 hours. Also it covers 40 km upstream and 48 km downstream in 9 hours. Find the speed of the boat in still water and that of the stream.

A boat goes 8 km upstream and then returns. Total time taken is 4 hours 16 minutes. If thespeed of current is 1 km/hr, find the actual speed of the boat.
