Answer:
Efficiency of the system = Actual output/ Effective capacity*100
Efficiency of the system = 850/950*100
Efficiency of the system = 0.894737*100
Efficiency of the system = 89.47%
Utilization of the system = Actual output/Design capacity*100
Utilization of the system = 850/1200*100
Utilization of the system = 0.708333*100
Utilization of the system = 70.83%
