Concept used
Work = Time × Efficiency
Calculation
Total work = LCM of 8, 20 and 24 = 120 units
Total efficiency = 120/8 = 15 unit/day
Ali's efficiency = 120/20 = 6 unit/day
Avtar's efficiency = 120/24 = 5 unit/day
Ashok's efficiency = 15 - (6 + 5) = 4 unit/day
Time taken by Ashok = 120/4 = 30 days
The answer is 30 days
