Correct Answer: 30
Solution : Let the total work be 1 unit. Ali can finish the work in 20 days. Ali's work rate = $\frac{1}{20}$ units per day. Avtar Singh can finish the work in 24 days. Avtar Singh's work rate = $\frac{1}{24}$ units per day. Ali, Avtar Singh, and Ashok together can finish the work in 8 days. The combined work = $\frac{1}{8}$ units per day. Ashok's work rate = $\frac{1}{8} - \frac{1}{20} - \frac{1}{24}$ units per day. Ashok's work rate = $\frac{1}{30}$ units per day. The number of days required by Ashok to complete the work = 30 days Hence, the correct answer is 30.
