Correct Answer - Option 3 : 24 days
Given:
Arjun is 33% as efficient as Abhishek.
They take 6 days to complete the work together.
Concept used:
Per day work = Total work/Total working day
Calculations:
Let the Abhishek's per day work be x units
Arjun per day work = 33.33% 0f x = x/3 units
Their total work per day = x + (x/3) = (4x/3) units
Total work in 6 days by both of them = 6 × (4x/3) = 8x units
Time taken by Arjun to complete the work = (8x/x/3) days
⇒ 24 days
∴ Option 3 will be the correct answer.
