Final answer:
The labor productivity is 25 KD/hour.
Step-by-step explanation:
The labor productivity can be calculated by dividing the total labor cost by the total number of hours worked. In this case, there are 7 workers who are paid 5 KD per hour, and they work for 9 hours per day, 6 days per week, and 4 weeks per month. So the total labor cost per month is 7 x 5 KD x 9 hours/day x 6 days/week x 4 weeks/month = 7 x 5 KD x 54 hours/week x 4 weeks/month = 7 x 5 KD x 216 hours/month = 37,800 KD. The total number of hours worked per month is 7 workers x 9 hours/day x 6 days/week x 4 weeks/month = 7 x 54 hours/week x 4 weeks/month = 7 x 216 hours/month = 1,512 hours. Therefore, the labor productivity is 37,800 KD / 1,512 hours = 25 KD/hour.
