- Initial Work Calculation:

- 40 men can complete the work in 18 days.

- Therefore, the work is 40 men × 18 days = 720 man-days.

- Work Done in Initial 9 Days:

- In 9 days, 40 men can complete 40 men × 9 days = 360 man-days.

- Remaining work = 720 man-days - 360 man-days = 360 man-days.

- Additional Men Joining:

- After 9 days, 5 more men join, making it 45 men in total.

- Time to Complete Remaining Work:

- Remaining work: 360 man-days.

- 45 men working: 360 man-days ÷ 45 men = 8 days.

- Conclusion:

- With 45 men, the remaining work will take 8 days to complete.

- Therefore, the correct answer is:

Option: 2 - 8 days
