- Fourteen persons can complete the work in 18 days.

- This means total work units needed = 14 persons × 18 days = 252 person-days.

- They worked for 5 days with 14 workers: 14 persons × 5 days = 70 person-days done.

- Remaining work = 252 - 70 = 182 person-days.

- After 5 days, only 8 persons are left.

- It takes 8 persons 182 person-days / 8 persons = 22.75 days to finish the remaining work.

- They worked 22 more days and on the last day (23rd day of remaining work), 6 workers came back.

- Therefore, total days worked after all interruptions: 5 days initially + 22 days remaining work = 27 days.

Your calculated answer: Option 1 - 27 is indeed correct.
