Question
If 24 workers can build a house in 40 days, how many workers will be required to build the same house in 20 days?
Solution
This problem can be solved using the concept of man-days which is a unit for a quantity of work done by an individual throughout a working day.
Step 1: Calculate the total man-days required to build the house. The total man-days required to build the house is the number of workers multiplied by the number of days. So, 24 workers * 40 days = 960 man-days.
Step 2: Calculate the number of workers required to build the house in 20 days. The number of workers required is the total man-days divided by the number of days. So, 960 man-days / 20 days = 48 workers.
Therefore, 48 workers will be required to build the same house in 20 days.
