The question in the image translates to the following:

**Problem:**
A store construction project can be completed by 15 workers in 2 weeks. If the project needs to be completed in 10 days, how many additional workers are required?

### Solution:

1. **Determine total work (in worker-days):**  
   - The total amount of work can be calculated as 15 workers × 14 days (2 weeks) = 210 worker-days.

2. **Calculate required workforce for 10 days:**  
   - To finish the same amount of work in 10 days, you need \( \frac{210 \, \text{worker-days}}{10 \, \text{days}} = 21 \, \text{workers} \).

3. **Find the number of additional workers required:**
   - Since 21 workers are needed, and the initial workforce is 15, the additional workers required are \( 21 - 15 = 6 \, \text{workers} \).

Thus, **6 additional workers** are needed to complete the construction in 10 days.

Would you like more details or have any questions about this solution?

Here are 5 related questions you might consider:
1. How would the required workers change if the project duration were reduced to 7 days?
2. What if the available number of workers remained constant but the days were reduced to 9?
3. Can this calculation be applied to different types of projects, such as building roads or bridges?
4. What happens if the productivity per worker changes?
5. How would adding breaks or days off affect the workforce needed?

**Tip:** Always check that your units (like worker-days or time) are consistent throughout the problem to avoid errors.
