Understanding Work Rate through a Comparative Analysis of Men and Women

In this article, we delve into an interesting problem that requires a detailed analysis of work rate and productivity among different groups of laborers, specifically men and women. We will explore the efficiency of various combinations of laborers in completing a task, ultimately determining the optimal number of workers needed to complete a task in the shortest possible time.

Problem Overview

The problem at hand is as follows: can 5 men or 6 women complete a task in 18 days, and how long would it take for a team of 15 men and 24 women to complete the same task?

Step-by-Step Solution

Step 1: Determine the Total Work in Terms of Man-Days or Woman-Days

First, we calculate the total work done by the given teams in terms of man-days and woman-days.

Total work done by 5 men in 18 days:

5 men × 18 days 90 man-days

Total work done by 6 women in 18 days:

6 women × 18 days 108 woman-days

Step 2: Establish the Relationship Between Men and Women

We then determine the work done by one man and one woman in a single day.

From the first equation:

5 men × 18 days 90 man-days

90m 90

m 1 unit of work per day per man

From the second equation:

6 women × 18 days 108 woman-days

108w 108

w 1 unit of work per day per woman

Step 3: Evaluate the Work Done by 15 Men and 24 Women in One Day

Next, we calculate the total work that 15 men and 24 women can do in one day.

Work done by 15 men per day:

15 men × 1 unit of work 15 units per day

Work done by 24 women per day:

24 women × 1 unit of work 24 units per day

Step 4: Total Work Done by 15 Men and 24 Women in One Day

Total work done per day by 15 men and 24 women:

15 men 24 women 15 24 39 units per day

Step 5: Determine the Number of Days Required to Complete the Task

We already know the total work to be 90 units. To find the number of days needed to complete the task:

Number of days, (d), required:

(d frac{text{Total work}}{text{Work done per day}} frac{90}{39})

(d approx 2.31 text{ days})

Therefore, 15 men and 24 women will complete the task in approximately 2.31 days.

Key Insights and Applications

This problem demonstrates the importance of understanding work rate and productivity in various labor scenarios. By analyzing the efficiency of different combinations of workers, we can better allocate resources and optimize labor in project management and task completion.

Conclusion

In conclusion, the work rate analysis presents a valuable tool for assessing the efficiency of different groups of workers. In the given example, we have shown that a combination of 15 men and 24 women can complete a task in approximately 2.31 days, which aligns with the initial conditions provided. This knowledge can be applied in a wide range of real-world scenarios, from construction projects to manufacturing lines.
