the incumbent Governor

by sanju09 » Tue May 26, 2009 5:42 am
Did the incumbent Governor get more than 50% of the votes cast by the public in the recall election (Challengers B and C were the only other candidates who fought the election)?

(1) Challenger B got 36% of the votes.

(2) Challenger C got 60000 out of a total of 100000 votes.

Correct, but let's elaborate a bit:

We want to know if the Gov got more than 50% of the votes. Since this is a yes/no question, a definite YES or a definite NO is sufficient.

(1) b got 36% of the votes

So, there are 64% of the votes remaining. COULD the Gov have gotten more than 50%? Sure. COULD the Gov have gotten less than 50%? Sure.

The Gov may or may not have gotten more than 50% - insufficient.

(2) c got 60% of the votes

Well, if c got 60%, then the MOST the Gov could have gotten is 40%. Therefore, the Gov definitely did NOT get more than 50% of the votes: sufficient.

(2) is sufficient, (1) is not: choose (B).
