0rex: It is not 20. You must be making the same mistake i made while trying to solve the question. Check the solution ^^^ again.

CaptJHMiller: I think it should be,
10*6=60days for 2 rooms for 1 worker
Then 1 room is 60/2=30days

Then for 4workers in a day is 30/4=7.5
4 workers in 6days is 7.5*6=45 days
