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
