Process sceduling

Question

 Consider the following process information. The Average Turn Around Time using Round Robin with time quantum = 1 is

                                                                                                                                                                                                                                                                                                                                            In the above problem my doubt is that ,should I consider both priority and Round Robin and solve the question or I can solve it just by considering Round Robin only ?

There is a scheduling process called priority based RR which i have only heard of.. in that case priorities should be considered..but the question only asks for RR ..so i guess the priorities are given to confuse maybe.. Did you get the answer using simple RR?

Answer 1

You should consider priority first and execute it in round robin manner.

Answer 2

Becoz their arrival time is not mentioned... so how are u going to decide which process to start with. Here instead of arrival time the priority is given and should be considered as a replacement of arrival time.
