A certain number of men can do a work in 60 days. If there were 8 men ...
Let there be x men in the group who can finish the work in 60 days.
X+ 8 men can finish the work in 50 days.
but x + 8 men take 60x/ (x+8) days
60x/ (x+8) = 50
So, x = 40

A certain number of men can do a work in 60 days. If there were 8 men ...
Number of Men in the Beginning: 40
Given information:
- A certain number of men can complete a work in 60 days.
- If there were 8 men more, the work could be finished in 10 days less.
Let's assume the number of men in the beginning is x.
So, x men can complete the work in 60 days.
If there were 8 men more, the number of men would be (x + 8) and the number of days required to complete the work would be (60 - 10) = 50 days.
Now, let's calculate the work done by x men in 60 days and (x + 8) men in 50 days.
Work done by x men in 60 days:
60 * x
Work done by (x + 8) men in 50 days:
50 * (x + 8)
According to the given information, both these works are the same. So we can equate them.
60 * x = 50 * (x + 8)
Now, let's solve this equation to find the value of x.
60x = 50x + 400
60x - 50x = 400
10x = 400
x = 400 / 10
x = 40
Therefore, there were 40 men in the beginning.
Hence, the correct answer is option A, 40 men.
Given information:
- A certain number of men can complete a work in 60 days.
- If there were 8 men more, the work could be finished in 10 days less.
Let's assume the number of men in the beginning is x.
So, x men can complete the work in 60 days.
If there were 8 men more, the number of men would be (x + 8) and the number of days required to complete the work would be (60 - 10) = 50 days.
Now, let's calculate the work done by x men in 60 days and (x + 8) men in 50 days.
Work done by x men in 60 days:
60 * x
Work done by (x + 8) men in 50 days:
50 * (x + 8)
According to the given information, both these works are the same. So we can equate them.
60 * x = 50 * (x + 8)
Now, let's solve this equation to find the value of x.
60x = 50x + 400
60x - 50x = 400
10x = 400
x = 400 / 10
x = 40
Therefore, there were 40 men in the beginning.
Hence, the correct answer is option A, 40 men.
