Problem 6. (3pts) A processor (CPU) involved in word-processing works as follows. During activity-A that lasts 19s the CPU is busy with wor-processing instruction execution. Then a 'print page' is issued. For that activity the CPU prepares the page for printing during activity-B that lasts 800ms. Then the CPU waits idly for 20s for the page to get printed, and when the page is printed in activity-C the CPU does a clean-up and a reset that lasts 200ms. Then it repeats its activities (A, B, C). This is the only thing the CPU is tasked to execute. (a) What is the elapsed time from the start of activity.A through the end of activity-C? Express your answer in seconds (b) What is the CPU utilization (express it as a percentage) for this overall CPU activity? (CPU utiliza- tion is when CPU is doing something and not waiting idly.) (c) What percentage of time is the CPU waiting idly? The two answers must add up to 100 percent
