10 hours

16 hours

12 hours

- Kavita can finish the whole work in 12 hours, so in 4 hours, she completes 4/12 = 1/3 of the work.

- That means 2/3 of the work is left after 4 hours.

- Komal alone can finish the job in 18 hours.

- For 1 unit of work, Komal needs 18 hours; so for 2/3 of the work, she needs (2/3) × 18 = 12 hours.

- Thus, Komal will take 12 hours to finish the remaining work.

- Option 1 (15), Option 2 (10), Option 3 (16), are not correct based on the calculations above.

Correct answer: Option 4 – 12 hours
