Best answer
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.
