Question 3 (10 points) A soft real-time system has four periodic events with periods of 50, 100, 150, and 300 msec each. Suppose that the four events require 10, x, 20, and 5 msec of CPU time, respectively. What is the largest value of x for which the system is schedulable? 3. Fig.3 The largest value of x is: (no need to include unit)
