Ответ:
So, you need 3 days approximately
Step-by-step explanation:
We will use Chain Rule to solve this question.
According to Chain Rule, the work efficiency remains constant.
•WWF×TWWF×T= Constant
•Here W = Work Done, WF = Workforce, T = Time.
Let the number of days needed be 'x'.
Applying Chain Rule,
10×9×6= 15×12×(x)
Or, x=3x=3 day
So, you need 3 days approximately.
