In a system using single processor, a new process arrives at the rate of six processes per minute and each such process requires seven seconds of service time. What is the CPU utilization?
Explanation: Number of processes per minute = 6
Burst time of each process = 7 secs
CPU utilization time within a minute = 6*7 = 42 secs % CPU utilization = useful time / total time * 100 = (42/60) * 100 = 70%
Option (A) is correct.
