Given:

Two persons P and Q can do a job together in 36 days.

P is 3 times as efficient as Q. 

Concept used:

Total work = Efficiency (Work done per day) × Total time taken

Calculation:

Let's suppose, P and Q do 3x and x units of work respectively.

Total work = 36(3x + x) = 144x units

Now, time taken by Q to complete the work alone = 144x ÷ x = 144 days

∴ Q alone will take 144 days to complete the work.
