Question

a company must make 400 units per day. the company has one 12 - hour shift. what is the efficiency if the total time to complete all tasks is 23 minutes and the company is using 18 workstations?
○ 50 percent
○ 22 percent
○ 71 percent
○ 88 percent

Explanation:

Step1: Calculate available daily time

First, convert the 12-hour shift to minutes: $12 \times 60 = 720$ minutes.
Total available time across all workstations: $720 \times 18 = 12960$ minutes.

Step2: Calculate required total task time

Total task time for 400 units: $400 \times 23 = 9200$ minutes.

Step3: Compute efficiency

Efficiency is the ratio of required task time to available time, converted to a percentage:
$\text{Efficiency} = \frac{\text{Total Required Task Time}}{\text{Total Available Time}} \times 100\% = \frac{9200}{12960} \times 100\% \approx 71\%$

Answer:

71 percent
