36 men can complete a piece of work in 18 days. In how many days will 27 men complete the same work?

None of these

To find the solution, first, calculate the total man-days required for the job: 36 men * 18 days = 648 man-days.

Then, divide the total man-days by the new number of men (27) to find the new number of days: 648 man-days / 27 men = 24 days.

So, the correct answer is 24.
