i just need the answer, no work

Given the three processes and the respective arrival times, and total CPU times shown in the table below, using FIFO scheduling, what is the end time for process p3? 3 12 8 Given the three processes and the respective arrival times, and total CPU times shown in the table below, using SJF, what is the start time for p2 ? Processes p1 and p2 execute on a system with a single CPU and 2 identical I/O devices. Each process executes a compute-bound phase followed by an I/O-bound phase. The system uses multiprogramming without time-sharing. The following table shows the lengths of each phase. p1 starts first at time 0. With multiprogramming, the computation terminates at time: 200100160
