Q1. E.
I can be wrong on this but given the time limit I would pick E.
4 variables - combined salaries and the total number of employees. (Even if we specify number of managers in terms of number of directors.)
Q3. 40% increase.
If B is doubled rate of reaction is halved.
To keep it same the rate of reaction has to be double.
That is have underroot 2 times the concentration of A.
Underroot 2 is 1.41 so it is 40% increase.

1. I have no clue, which means my answer is E (I am sure you wouldn't have posted it if it was E). So let's wait for the others to join the party. 
2. Here I think either p or q has to be = 5. so we can definitely say pq * n is so my answer is D
3. Ca^2/Cb = Constant.
(xCa)^2 = (Constant)*2*Cb so x=1.414 or 40% increase (D)
