In an election with only two candidates, before absentee ballots were counted candidate Jones received a votes and candidate Smith received b votes. If 900,000 non-absentee votes were cast, what was the percent change in the number of votes after the counting of absentee ballots?
(1) Candidate Jones received 43% of the votes cast before absentee ballots were counted and received 43% after absentee ballots were counted.
(2) Candidate Smith received 57% of the votes cast both before and after absentee ballots were counted and received 387,000 votes after absentee ballots were counted.
(1) Candidate Jones received 43% of the votes cast before absentee ballots were counted and received 43% after absentee ballots were counted.
So, Jones received 43% of absentees votes too, but we cannot say anything about the number of absentees votes..
Insuff
(2) Candidate Smith received 57% of the votes cast both before and after absentee ballots were counted and received 387,000 votes after absentee ballots were counted.
So, Smith received 57% of absentees votes too, and 57% of absentees votes = 387000...absentees votes =\(\frac{387000}{57}*100\)
Sufficient

Bunuel, the number 387000 is not divisible by 57, so the number of votes becomes non-integer. But 387000 is divisible by 43, so maybe we can interchange the % in each statement. Or make it that smith did not get 387000 absentee votes.
