Final answer:
To calculate the labor productivity ratio, divide the total number of units produced by the total number of worker-hours. To calculate the units of output per worker-month, multiply the units of output per worker-hour by the total number of hourly workdays in a month. The productivity index for the next month can be calculated using the same formulas.
Step-by-step explanation:
In order to calculate the labor productivity ratio, we need to determine the units of output per worker-hour and per worker-month.
To calculate the units of output per worker-hour, divide the total number of units produced (7200) by the total number of worker-hours (10 workers x 8 hours/day x 22 days/month = 1760 hours). The labor productivity ratio is 7200 units / 1760 hours = 4.09 units/hr.
To calculate the units of output per worker-month, multiply the units of output per worker-hour (4.09 units/hr) by the total number of hourly workdays in a month (8 hours/day x 22 days/month = 176 hours). The labor productivity ratio is 4.09 units/hr x 176 hours = 720 units/month.
For the next month, with 20 workdays and 6800 units produced, we can use the same calculations to determine the productivity index:
(a) Units of output per worker-hour: 6800 units / (10 workers x 8 hours/day x 20 days/month) = 3.27 units/hr
(b) Units of output per worker-month: 3.27 units/hr x (8 hours/day x 20 days/month) = 654 units/month
