it's E guys.

statmt 1: we do not know if there are any apts between 500 and 600$ rent.

statmt 2: we do not know how many apt cost each either 450 or 500 $ rent.

Combining the two we know that there are half of the apts which cost 450$ each, but we don't know if there are any that cost 500$.

# of apts = x => total rent=600x

% of apt with rent

 

statement 1: Half of these apartments have a rent price lower than $500.

x/2 pay not sufficient

 

statement 2: There are four prices, $450, $500, $650, $800.

how many pay each of prices? -> not sufficient

 

statement 1&2: rent of half x/2 pay 450 => rent paid by other half => 600x-(450x/2) = 375x

avg. for other half = 375x/(x/2) = 700

 

not enough to find # of apt with rent not sufficient

 

answer = E
