Answer 1

Given:

A contractor employed 210 workers to unload goods from a ship in 18 days.

To find:

how many more men should be employed to finish the work in the time

Solution:

We have given the situation of the question as:

After 4 days it was found that only 1/6 part of the work was done

so with the same efficiency

The total work will be done by 210 workers in 24 days

Let the X number of workers is required to complete the work on time.

So, by the MDH formula, we get the number of the workers to complete the remaining works  as:

• 210×20 = X×14
• X = 210×20/14
• X = 300

so,

90 workers should be employed to finish the work in the time
