Answer:
The correct answer is option b.
Explanation:
A dairy is producing 960 gallons of milk per day.
Each milker works 8 hours and produces the same amount of milk.
For per hour of labor the diary produces 12 gallons of milk.
Quantity of milk produced by a labor in 8 hours
= [tex]Production\ in\ one\ hour\times No.\ of\ hours[/tex]
= [tex]12\times 8[/tex]
= 96 gallons
The number of workers required to produce 960 gallons per day
= [tex]\frac{Total\ daily\ Production}{Daily\ production\ by\ each\ labor}[/tex]
= [tex]\frac{960}{96}[/tex]
= 10 workers
