Please answer this question about IO/ CPU bound processes and thank you!. 

Question 12
Consider a system running 11 1/0-bound processes and 3 CPU-bound processes. Assume that the I/O-bound
processes issue an I/O operation once for every millisecond of CPU computing and that each I/O operation
takes 10 milliseconds to complete (we assume that there is no competition among 1/0 operations). Assume
that the CPU-bound processes do not issue any 1/0 operations. A round-robin scheduler with quantum size 3
milliseconds is used to schedule all these (11+3) processes together. We assume that the context-switching
overhead is 0.1 millisecond and that all processes are long-running tasks. Calculate the CPU utilization (keep
three decimal values).
