Consider a Three Sequentially Stepped Process Named as Process A

Multiple Choice

Consider a three sequentially stepped process named as Process A, Process B, and Process C. Input comes into Process A. Output from A goes into Process B. Output from B goes into Process C. Output of C is the final output. Suppose that it takes 2 minutes per unit in Process A, 3 minutes per unit in Process B and 1 minute per unit in Process C. What will be maximum steady state output from this system?

A) 30 per hour
B) 60 per hour
C) 20 per hour
