Five jobs are waiting to be processed. Their processing times and due dates are given below. You want to schedule the jobs using the critical raio scheduling rule.

Job

Processing Time$($days$)$

Job Due Date$($days$)$

A

$12$

$12$

B

$8$

$15$

C

$15$

$10$

D

$18$

$17$

E

$-$ Assume that all jobs arrived on day $0.$

$-$ Today$($current day$)$ is day $0.$

$$TIP: if today is day $0$ and Job$$ C$\text{'}$s processing time is expected to be $15$ days, the workdays remaining for job C is $15$ days.
