Assume that an assembly line has three tasks that must be completed (in order, A, B, C, and D). The tasks have processing times of 8, 12, 9, and 10 minutes per unit, respectively. If the assembly line operates for 500 minutes per day with a desired output of 50 units per day, what is the efficiency of the assembly line?
A) 90%
B) 95%
C) 97.5%
D) Cannot be determined from the information given

Question

Quizplus · Accepted Answer

The total processing time per unit is 8 + 12 + 9 + 10 = 39 minutes. For 50 units, the total time required is 50 * 39 = 1950 minutes. The assembly line operates for 500 minutes, so efficiency = (500 / 1950) * 100% = 25.64%. None of the given options match this, so the correct choice is that the efficiency cannot be determined from the given options.
