In 1997, N people graduated from college. If 1/3 of them received a degree in the applied sciences, and, of those, 1/4 graduated from a school in one of six northeastern states, which of the following expressions represents the number of people who graduated from college in 1997 who did not both receive a degree in the applied sciences and graduate from a school in one of six northeastern states?
(A) 11N/12
(B) 7N/12
(C) 5N/12
(D) 6N/7
(E) N/7
(A) 11N/12
(B) 7N/12
(C) 5N/12
(D) 6N/7
(E) N/7
[Reveal] Spoiler:
In this question How can we assume that there a zero (0) people who have no degree in applied science and no graduates in one of six NE states? Its not specified in the problem.
4 equations
Degree in Applied Science + Graduate in six schools = Equation A
Degree in Applied Science + Did not graduate from six schools = Equation B
No Degree in Applied Science + Graduate in six schools = Equation C
No Degree in Applied Science + Did not graduate from six schools = Equation D
I think, the problem is assuming "Equation D" to be Zero. BUt I am confused as how to interpret this?
