Answer 2

Answer:

9 men, can complete the work in $48$ days.

Step-by-step explanation:

36 men can do a piece of work in 12 days.

Therefore, 36 men, each day can complete $\frac{1}{12}$ part of the work.

Therefore, each man, each day can complete $\frac{1}{12}.\frac{1}{36}$ part of the work.

Therefore, 9 men, each day can complete $\frac{1}{12}.\frac{1}{36} . 9$ part of the work.

Therefore, 9 men, can complete the work in $12 . 36 . \frac{1}{9}$ days $= 48$ days.
