In k years Frank's age, in years, will be A. 4k B. 5k C. 6k D. 7k E. 8k Let k=10. 2k years ago Frank was 3k years old. Since k=10, 20 years ago Frank was 30 years old, implying that his age now = 30+20 = 50. In k years Frank's age, in years, will be: Since Frank is now 50 years old, Frank's age in 10 years = 50+10 = 60. The correct answer must yield a value of 60 when k=10. Only C works: 6k = 6*10 = 60. The correct answer is C. _________________ 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.

Mitch has solved the question using the input-output approach, so let's use the algebraic approach. 2k years ago Frank was 3k years old. We're given Frank's age 2k YEARS AGO. So, Frank's PRESENT age = 3k + 2k = 5k In k years Frank's age, in years, will be In k years, Frank will be k years older than his CURRENT age. So, IN k YEARS, Frank's age will equal 5k + k = 6k Answer: C Cheers, Brent _________________ Brent Hanneson â€“ Creator of GMATPrepNow.com Use our video course along with Sign up for our free Question of the Day emails And check out all of our 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 Apr 2015 Posted: 2424 messages Followed by: 18 members Upvotes: 43 AAPL wrote: Magoosh 2k years ago Frank was 3k years old.
