![A single processor system has to execute six
jobs L, M, N, O, P and Q having priorities 4,
7(high), 6, 6, 1(low) and 3 with arrival time(AT) at
5, 4, 3, 1, 2 and 6 units respectively. Their burst
time(BT) requirements are 5, 6, 7, 9, 2 and 3
units respectively. If two process comes at same
time in a queue then order is followed i.e, L has
the highest priority and P has the lowest priority.
Let the average waiting time by using Round
Robin scheduling with time slice of 3-time unit is
"x" unit and using Priority based (Non pre-
emptive) scheduling is "y" unit. Then find the
value of y - x. (Answer up to 2 decimal place)?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fff75db58-a904-43eb-815c-1e32af1c6c93%2F728f3891-6609-41db-992c-657b0329e9d0%2Fr5dcrd8_processed.jpeg&w=3840&q=75)
