Consider the following table :

Assume all process arrived at same time. 1st process P1 stars execution from ‘0’ time unit. Every process completes its CPU request then get I/O service. If any two process need same amount of CPU time then prefer the process which has less amount of I/O service request. Process are scheduled using SJF for CPU service and I/O scheduling is done using FCFS scheduling, the time at which process P1 completes both CPU and I/O requests is

MY DOUBT IS:How these two things are possible simultaneously "1st process P1 stars execution from ‘0’ time unit" AND ". Process are scheduled using SJF for CPU service "??

anyone help?
