In Gulshan the ratio of private homes to apartment is 3:5. If all the apartments are brick made and 1/10 of the private homes are wooden, what is the maximum portion of houses that may be brick?

    My first thought is what else can private homes be made of (remembering the three little piggies). Straw? Steel? Mud?
    Next, is terms: is an apartment a house? Lets assume our way out of that one...change the question to what is the maximum portion of private homes that may be brick.

    Let H be homes.
    then 1/10 H are not brick.
    assume 9/10 are brick

    Then ratio becomes brick homes/apartments = .9(3/5)=27/50
