Final answer:
The capacity efficiency of the workshop is 77.8%, which is determined by the output of 70 cars per month divided by the effective capacity of 90 cars per month.
Step-by-step explanation:
The capacity efficiency of the workshop operating within the CBD precinct of a major South African city can be determined by the ratio of actual output to effective capacity, expressed as a percentage. The actual output is given as 70 cars per month, and the effective capacity is 90 cars per month. Thus, the capacity efficiency is calculated as (Actual Output / Effective Capacity) * 100 = (70 / 90) * 100 = 77.8%.
EQUIRED: a specific, calculated percentage to measure efficiency is needed to complete the analysis, and in this case, the answer is option B, 77.8%.
