Task Analysis

To solve this problem, we need to determine the following: 1. How many days will it take for 3 workers to complete the task? 2. How many workers are needed to complete the task in 6 days?

Calculation

Let's start by calculating the number of days it will take for 3 workers to complete the task. We'll use the given information that 4 workers completed the task in 9 days.

The formula for this calculation is: \[ \text{Number of days} = \frac{\text{Number of workers} \times \text{Number of days}}{\text{Number of workers}} \]

Substituting the given values: \[ \text{Number of days} = \frac{4 \times 9}{3} = 12 \]

So, it will take 3 workers 12 days to complete the task.

Next, we'll calculate how many workers are needed to complete the task in 6 days. We'll use the same formula:

\[ \text{Number of workers} = \frac{\text{Number of workers} \times \text{Number of days}}{\text{Number of days}} \]

Substituting the given values: \[ \text{Number of workers} = \frac{4 \times 9}{6} = 6 \]

So, it will take 6 workers to complete the task in 6 days.

Therefore, 3 workers will complete the task in 12 days and 6 workers are needed to complete the task in 6 days.
