Explanation / Answer
6) Output = 57600 heaters
Let the number of laborers employed = L
Each laborer work 200 hours per month. So per year each laborer will work 200 x 12 months = 2400 hours
So total labor hour input = number of laborers employed x labor hour per worker = L x 2400 = 2400L
Labor productivity = output / labor hour input
=> 0.25 = 57600 / 2400L
=> 2400L = 57600/0.25
=> 2400L = 230400
=> L = 230400/2400
=> L = 96
So the number of laborers employed by the plant = 96
