36 men can complete a piece of work in 18 days. In how many days will ...
Given:
- 36 men can complete a piece of work in 18 days.
To find:
- In how many days will 27 men complete the same work?
Solution:
Let's assume that the work done is W.
Work done by 36 men in 1 day = W/18 (since they complete the work in 18 days)
Work done by 1 man in 1 day = (W/18) / 36 = W/648
Now, we need to find the number of days it will take for 27 men to complete the work.
Let's assume that it will take D days for 27 men to complete the work.
Work done by 27 men in 1 day = (W/648) * 27 = W/24
Since the work done by 27 men in 1 day is W/24 and we want to find the number of days it will take for them to complete the work, we can set up the following equation:
(W/24) * D = W
Simplifying the equation:
D/24 = 1
D = 24
Therefore, 27 men will complete the same work in 24 days.
Hence, the correct answer is option A) 24 days.
