Consider the four processes with burst times of 100, 200, 300, and 400 all processes arrived at time 0. Each process spends first 10% of its execution time doing I/P, next 40% time doing CPU operations, next 20% time doing I/O and last 30% time doing CPU operations. The system uses Shortest Remaining Time First (SRTF) algorithm for scheduling. Calculate the completion time of P3?
