I would guess that the answer is E, i.e. 11-x>0 Here is my reasoning: If (x-11)(x-3)<0 then at least one of them must be negative. Intuitively then, x-11 is the negative part and x-3 is positive because in the former case you subtract a larger number. x-11<0 | *(-1) 11-x>0 Any other takers?

My guess is that A is the correct answer. If you know that the slope is negative then the line will definitely cross the second quadrant (just draw the system of coordinates and see it for yourself). (2) is insufficient in my opinion because the line could be upward sloping with the intercept of -6 ...

Could someone please explain the second sentence? i.e. seating arragements are considered different only when the positions of the people are different relative to each other.

Without even getting into the math, which is actually very simple as I noticed, I was bogged down by the phrasing.

IMO also A. What's the OA?

Thanks awesomeusername.

Then, I gather that there is little to no repetition in quant problems between the Main OG book and the OG Quant Review book? Am I correct?
