An assembly line consists of 158 tasks grouped into 32 workstations. The sum of all task times is 105 minutes. The largest assigned cycle time is 4 minutes. The efficiency of this line is approximately
A) 8 percent
B) 21 percent
C) 82 percent
D) 100 percent
E) none of the above

Question

Quizplus · Accepted Answer

Efficiency of the line can be calculated as:

Efficiency = (Total task time / (Number of workstations * Cycle time)) * 100

Total task time = 105 minutes 
Number of workstations = 32 
Cycle time = 4 minutes

Efficiency = (105 / (32*4)) * 100 = 82.03%

Therefore, the efficiency of the line is approximately 82%, which corresponds to choice C.
