Answer:
It will take 8 men 45 days to build a similar wall.
Step-by-step explanation:
To solve this problem, we can use the concept of "man-days" which represents the amount of work a man can do in one day.
Given:
- 12 men can build a wall in 30 days.
- We need to find out how long it will take 8 men to build a similar wall.
1. First, we calculate the total man-days required to build the wall. This is done by multiplying the number of men by the number of days it takes for them to complete the wall.
Total man-days = 12 men * 30 days = 360 man-days
2. Now, we need to find out how many days it will take 8 men to build the wall. We divide the total man-days by the number of men working on the wall.
Days required = Total man-days / Number of men
= 360 man-days / 8 men
= 45 days
Therefore, it will take 8 men 45 days to build a similar wall.
