C 7 15
D 6 17

a.
Sequence the jobs using (1) First come, first served, (2) Shortest processing time, (3) Earliest due date, and (4) Critical ratio. Assume the list is by order of arrival.

Sequence for First come, first served (Click to select)A-B-C-DD-C-B-AC-B-D-AA-C-D-B
Sequence for Shortest processing time (Click to select)D-C-B-AA-C-D-BC-B-D-AA-B-C-D
