Of the C condominiums in a certain building complex, 2/3 have at least two bedrooms. If, of those, 1/4 have at least two bathrooms, which of the following expressions represents the number of condominiums in the complex with at least two bedrooms that do not have at least two bathrooms?
(A) C/2
(B) C/3
(C) C/4
(D) C/6
(E) C/12
Let \(C\) be 1200
So, Condominiums with atleast 2-BRs = \(\frac{2}{3}(1200) = 800\)
Now, out of these Condominiums, ones with atleast 2-Baths = \(\frac{1}{4}(800) = 200\)
And, out of these Condominiums, ones which do NOT have atleast 2-Baths = \(800 - 200 = 600\)
Plug in C as 1200 and check for option choices.
Hence, option A
