Two weeks ago LUML produced 300 light fixtures using eight employees. Each employee worked a standard week of 40 hours. Last week the company produced 240 standard fixtures using six employees who each worked 36 hours. In which period was productivity greater? Explain.
The first statement claims that 300 light fixtures were produced by eight employees where each employee has worked for a standard week of 40 hours.
Thus, the total number of hours worked by eight employees is 40*8 = 320 hours.
Now, two weeks ago, total number of light fixture produced by using 1 hour of time is given by = 300/320 = 0.9375
Week | Light fixture | Employees | work time /week | Total hours work in a week |
2 week ago | 300 | 8 | 40 | 320 |
Last week | 240 | 6 | 36 | 216 |
Similarly, last week total light fixture produced was 240. A total number of hours worked by six employees last week is = 36*6 = 216.
Now, last week, a total number of light fixtures produced by using 1 hour of time is given by = 240/216 = 1.112.
We have obtained that average amount of light fixtures produced last week (1.112 per hour) is greater than the two weeks ago (0.9375 per hour).
Thus, last week the productivity is better than two weeks ago.
