The following table describes three different periodic tasks (t, t2, ta). These tasks need to be scheduled using the rate monotonic (RM) technique. All the time values are following the same unit (say seconds).
Task Execution time (e) Period (p)
t 10
t2 3
t3 15
At what time will the first occurrence of task 3 complete? (just type the number, the unit is not needed)
