Consider a system running ten I/O-bound tasks and one CPU-bound task. Assume that the I/O-bound tasks issue an I/O operation once for every 4 milliseconds of CPU computing and that each I/O operation takes 10 milliseconds to complete. Also assume that the context-switching overhead is 2 milliseconds and that all processes are long-running tasks. Calculate the CPU utilization for a round-robin scheduler when the time quantum is 10 milliseconds (the result should be in the form of percentage, rational expression, or a ratio of two integers, such as 25/88, 81/121).
