1. A time study specialist has set the production rate for each worker on a job at 22 units every therre hours. At this rate, what is the minimum number of workers that should be put on the job, if at least 90 units are to be produced per hour?
- A. 5
- B. 5
- C. 5
- D. 5
Answer: Option D
Explanation:
The rate for each worker can be expressed as 22/3 units per hour.
We can let n = the number of workers needed to produce 90 units per hour, and we have:
n(22/3) = 90
or,22n = 270
∴ n = 270/22 = 12.2,
so there must be at least 13 workers.(ans)
