Quizplus · Accepted Answer

The critical ratio (CR) is calculated as $CR = \frac{\text{Time until due}}{\text{Processing time remaining}}$. Jobs are sequenced in ascending order of their CR values. Calculating CR for each job: A = $\frac{24-20}{4} = 1$, B = $\frac{28-20}{7} \approx 1.14$, C = $\frac{24-20}{8} = 0.5$, D = $\frac{28-20}{6} \approx 1.33$, E = $\frac{22-20}{5} = 0.4$. Sequence: E-C-A-B-D.
