Hi experts,
Even though I have read all the above comments I still can't understand why I should choose B over E. Could somebody shed some light on this problem?
West Egg had more mansions per capita last year than East Egg, while East Egg had slightly fewer residents than West Egg
Mansion at West Egg = A. Mansions at East egg = B.
Residents at West Egg = X. Residents at East egg = Y.

and Y< X

Since the census, West Egg and East Egg have each seen the demolition of a dozen dilapidated mansions within their respective borders, and no new mansions have begun constructionThe trick is to understand the "a dozen" is literally 12 mansions, and it is not used figuratively to mean considerable number of mansions.
Another observation is a year has passed since the demolition. Hence, we do not know the change in population within the year.
Hence after demolition, the inequality remains A-12 > B-12
Option B: West Egg has more mansions than East Egg.
Exactly what the inequality A-12 > B-12 says
Option E: West Egg has more residents than East Egg
As mentioned before, we are not sure what the change has been in the population since the census
We have not been given any statement about the number of people after
