Official Explanation

We begin by symbolizing the statements. “ No one will be admitted to Yale Law School unless he or she studies hard for the LSAT ” can be symbolized as

~SH—>~Y,

where SH stands for “ he or she studies hard for the LSAT, ” and Y stands for “ admitted to Yale Law School. ”

The second condition appears confusing at first but is actually straightforward once we get around the obfuscating tactics. “No one studied hard for the LSAT unless he or she was not a graduate from Tri-State University” can be symbolized as

~(~G)—>~SH,

where G indicates “ a graduate of Tri-State University. ” Recalling that two negatives make a positive, we simplify this to

G—>~SH

Using the transitive property to combine this with the first premise, ~SH—>~Y, yields

G—>~Y

In other words, if a person graduated from Tri-State University, he or she was not admitted to Yale.  The answer is (A).

Was just in the process of mapping the facts when the official explanation was posted lol. What luck....

This is an LSAT Inference question all the way. Such heavy use of conditional logic generally does not appear on the GMAT. Nevertheless, it is good practice.

No one will be admitted to Yale Law School unless he or she studies hard for the LSAT.

This means  Yale  is subset of  studies hard for LSAT

No one studied hard for the LSAT unless he or she was not a graduate from Tri-State University.

This means  studies hard for LSAT  is a subset of  not tri-state uni grad

Think in terms of venn diagrams.  Yale  is enclosed by  studies hard for LSAT , which in turn is enclosed by  not tri-state uni grad.   So tri-state uni grad is outside of all the circles. Now the answer becomes trivial:

No one will be admitted to Yale Law School unless he or she studies hard for the LSAT. No one studied hard for the LSAT unless he or she was not a graduate from Tri-State University.

Which one of the following conclusions necessarily follows from the above statements?

(A) No graduate of Tri-State University was admitted to Yale Law School. -> Yes,  tri-state uni grad  has no overlap with  Yale

(B) Some graduates of Tri-State University were admitted to Yale Law School. -> No,  tri-state uni grad  has no overlap with  Yale

(C) All graduates of Tri-State University studied hard for the LSAT. -> No,  tri-state uni grad  has no overlap with  studies hard for LSAT

(D) Only graduates of Tri-State University did well on the LSAT. -> No, nothing was said about doing well on LSAT, just that some students worked hard

(E) Only college graduates did well on the LSAT. -> No, nothing was said about doing well on LSAT, just that some students worked hard
