Question

10 men who work 9hours per day, complete half of a work in 6days. How many days required for 15 men who work 12 hour per day to complete the rest of the work ​

Answer 1

Answer:

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.
