Actually, the best answer is 5 days, however, if not then the next best would be 20 days because as per textbooks the carbonaceous BOD is satisfied in 20 days and after that Nitrogenous BOD is satisfied.
Now we know Carbonaceous demand is for oxidation of organic matter, whereas Nitrogenous demand is for oxidation of ammonia.
So, here 20 is the right answer
