Given information:

Number of workers = 1800

Number of days = 50


Calculation:

Let's assume the total work to be done is represented by W.

Therefore, the work done by the 1800 workers in 50 days is given by:

1800 workers * 50 days = W

Work done = 90000W


Finding the work done in 1 day:

To find the work done in 1 day, we need to divide the total work done by the number of days:

Work done in 1 day = 90000W / 50 = 1800W


Finding the number of workers needed to complete the work in 30 days:

Let's assume the number of additional workers needed to complete the work in 30 days is represented by x.

If the work is completed in 30 days, the work done in 1 day will be:

Work done in 1 day = W / 30


Equating the work done:

Since the amount of work done is the same, we can equate the two expressions for the work done in 1 day:

1800W = W / 30


Simplifying the equation:

We can simplify the equation by canceling out the common factor of W:

1800 = 1 / 30


Finding the number of additional workers needed:

To find the number of additional workers needed, we need to subtract the initial number of workers from the new number of workers:

Additional workers needed = x - 1800


Calculating the number of additional workers needed:

We can calculate the number of additional workers needed by solving the equation:

1800 = 1 / 30

x - 1800 = 1 / 30

x = 1 / 30 + 1800

x ≈ 1866.67


Conclusion:

Therefore, approximately 1867 additional workers should be employed to complete the work in 30 days.
