Answer 1

the answer is non of these ok

Answer 2

Answer:

20 days is the answer

Step-by-step explanation:

12 men work 45 days, that is 12 × 45 = 540 days to complete the task.

If we have 27 men available, and assume the same work, they will also need 540 days. But as they are more, the time needed will be 540/27 = 20 days.

So, it takes 20 days for 27 men to do the same work.
