Final answer:
The efficiency of the plant for the past month is 64.62%, calculated by dividing the actual output by the effective capacity and then multiplying by 100.
Step-by-step explanation:
To calculate the efficiency for the past month at the plant, we need to divide the actual output by the effective capacity and then multiply by 100 to get a percentage. The plant's effective capacity is 6,500 hammers per day, but it has only been producing 4,200 hammers per day due to material delay, employee absences, and other problems.
Efficiency = (Actual Output / Effective Capacity) × 100%
Efficiency = (4,200 hammers / 6,500 hammers) × 100% = 64.61538...
Rounded to two decimal places, the efficiency for the past month is 64.62%.
The efficiency of the plant can be calculated by dividing the actual production (4,200 hammers per day) by the effective capacity (6,500) and multiplying by 100 to get the result as a percentage.
The calculation would be:
Efficiency = (Actual Production / Effective Capacity) * 100
Efficiency = (4,200 / 6,500) * 100 = 64.62%
Therefore, the efficiency of the plant for the past month is approximately 64.62%.
