OA B Source: Princeton Review Given: Brady, Charlie, and Daryl play on the same baseball team. Target question: The number of home runs hit by Brady in a particular season is what fraction of the total home runs hit by the three players in that season? This is a good candidate for rephrasing the target question. Let B = number of home runs that Brady hit Let C = number of home runs that Charlie hit Let D = number of home runs that Daryl hit So, B + C + D = the TOTAL number of home runs hit So, the fraction of the total home runs that Brady hit = B/(B + C + D) REPHRASED target question: What is the value of B/(B + C + D)? Aside: Hereâ€™s a video with tips on rephrasing the target question: http://www.gmatprepnow.com/module/gmat-data-sufficiency?id=1100 Statement 1: Brady hit 12 home runs in that season. Since we have no information about the number of home runs that Charlie (C), and Daryl (D) hit, there's no way to answer the REPHRASED target question with certainty. So, statement 1 is NOT SUFFICIENT Statement 2: In that season, the number of home runs hit by Brady was twice the number hit by Charlie and Daryl combined. So, we can write: B = 2(C + D) = 2C + 2d Now take B/(B + C + D) and replace B with 2C + 2d to get: (2C + 2D)/(2C + 2D + C + D) Simplify to get: (2C + 2D)/(3C + 3D) Factor top and bottom to get: 2(C + D)/3(C + D) Simplify to get: 2/3 So, the answer to the REPHRASED target question is B/(B + C + D) = 2/3 Since we can answer the REPHRASED target question with certainty, statement 2 is SUFFICIENT Answer: C Cheers, Brent _________________ Brent Hanneson â€“ Creator of GMATPrepNow.com Use my video course along with Sign up for free Question of the Day emails And check out all of these free resources GMAT Prep Now's comprehensive video course can be used in conjunction with Beat The GMATâ€™s FREE 60-Day Study Guide and reach your target score in 2 months! ### GMAT/MBA Expert GMAT Instructor Joined 25 May 2010 Posted: 15362 messages Followed by: 1866 members Upvotes: 13060 GMAT Score: 790 BTGmoderatorDC wrote: Brady, Charlie, and Daryl play on the same baseball team.

Statement 2: For every 2 home run hits made by Charlie and Daryl combined, Brady made 4 home run hits, implying that Brady made 4 of every 6 home run hits: 4/6 = 2/3. SUFFICIENT. The correct answer is B. _________________ Mitch Hunt Private Tutor for the GMAT and GRE GMATGuruNY@gmail.com If you find one of my posts helpful, please take a moment to click on the "UPVOTE" icon.
