* A complicated DC Math

[Jason.tuyj]

Development planners determined the number of new housing untis needed in a certain area by using the formular H=kJ, where H is the number of new housing units needed in the area, J is the number of new jobs to be created in the area, and k is a constant. How many new housing units did the planners determine were needed?

(1) The number of new jobs to be created was 60,000
(2) According to formular used by the planners, if 37,500 jobs were to be created, then 7,500 new housing units would be needed.


Why B doesn't answer the question, I think it also tells 7,500 new housing units needed.

From problem statement, H = KJ. To find H we need to know both the constant and the number of new jobs.

1) Gives us J, We dont have the value of K. Hence Insufficient.
2) Says IF the jobs are 37500 then housing units needed are 7500. [ Its a projection not the actual data.]
In other words, it gives us only K. K = H/J = 7500/37500 = 1/5.
J is not provided. Hence Insufficient.

Combining both 1 and 2, we have both K and J.
Answer should be C
