What if the question is modified a bit? Could you help me by removing other choices with the EASIEST way in the new version that i modified?

It doesn't matter what the question is. Think this way:
P - Selling price is $20
Q - Selling price is $17
If equal quantities of the two are sold, the average selling price would be right in the middle, i.e. 18.5.
Now, if you sell P more, avg selling price will move toward 20.
But if you sell Q more, avg selling price will move toward 17.
So if Q are more than P in number, avg will lie between 17 and 18.5 (exclusive if both are sold)
If P are more in number than Q, avg will lie between 18.5 and 20 (exclusive if both are sold)
