Correct Answer: 12 days
Solution : Given: A and B together can finish a job in 24 days, while A, B and C together can finish the same job in 8 days. Then in 1 day A and B together can finish $\frac{1}{24}$th part of the job. Also, A, B, and C together can finish the same job in 8 days. ⇒ In 1 day A, B, and C together can finish $\frac{1}{8}$ part of the job. Then C alone in 1 day can finish $(\frac{1}{8}-\frac{1}{24}) = (\frac{3-1}{24}) = \frac{2}{24}$th part of the job $\therefore$ C alone will finish the job in $=\frac{1}{\frac{2}{24}} = \frac{24}{2}=12$ days Hence, the correct answer is 12 days.
