44 men can do a piece of work in 48 days. The number of men required to complete the same work in 8 days is:

Correct option is B

Given:

44 men can do a piece of work in 48 days.

Concept used: 

The concept of man-days.

$$Total \ work = \ Number \ of \ men × \ Number \ of \ days \times \ Efficiency$$ 

Solution:

$$Total \ work= 44 \ men \times 48 \ days = 2112 \ man-days.$$ 

Let the required number of men be xxx to complete the same work in 8 days.

The total work remains the same (2112 man-days)

$$x \times 8 = 2112$$ 

$$x = \frac{2112}{8}$$ 

$$x = 264 \ men$$ 

The number of men required to complete the work in 8 days is 264 men.
