- Aarush and Maahi together finish the work in 10 days.

- Aarush alone completes the same work in 15 days.

- Let’s find Maahi’s time:

- Aarush’s work rate = 1/15 (work/day)

- Together, their rate = 1/10 (work/day)

- Maahi’s work rate = 1/10 - 1/15 = 1/30 (work/day)

- Therefore, Maahi will take 30 days to finish the work alone.

- Option 1: 25 days - Incorrect

- Option 2: 15 days - Incorrect

- Option 3: 30 days - Correct

- Option 4: 20 days - Incorrect
