Each customer buys exactly one sandwich. If there were 300 customers yesterday, what fraction of veggie melts sold yesterday were bought by female customers? (1) 1/2 of all sandwiches sold yesterday were tuna melts, and 1/3 of all customers yesterday were male. (2) Yesterday, twice as many tuna melts were bought by females as there were veggie melts bought by males. The OA is C.

There can be any no. of Balls in the box. But, At least one means surely there will be one but can be more of the same type. If I say I have at least 100US$ doesn't that mean that surely I have US $100 but might have more but not less. Is my understanding correct?? Can anyone help, please? Thanks! Given "From any two balls from the box, at least one is a red ball," we can conclude that there is only one blue ball. If there were greater than 1 blue ball, say 2 blue balls, and we randomly pick two balls, there is a possibility that both the balls are blue. But this will invalidate Statement 1, which is not warranted. Thus, there is only one blue ball. Hope this helps! -Jay _________________ Manhattan Review Locations: Manhattan Review Chennai | GMAT Prep Himayatnagar | GRE Prep Hyderabad | Bangalore GRE Coaching | and many more...

Statement 1 indirectly tells us that it's IMPOSSIBLE to select 2 blue balls. So, the box must contain fewer than 2 blue balls. Since we're told that the box contains AT LEAST 1 blue ball, we can be certain that there is EXACTLY 1 blue ball. As far a red balls are concerned, all we know for sure is that there is at least 1 red ball. That said, there could also be 2 red balls, 3 red balls, 4 red balls, etc 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! • Free Trial & Practice Exam BEAT THE GMAT EXCLUSIVE Available with Beat the GMAT members only code • Magoosh Study with Magoosh GMAT prep Available with Beat the GMAT members only code • Get 300+ Practice Questions 25 Video lessons and 6 Webinars for FREE Available with Beat the GMAT members only code • 5 Day FREE Trial Study Smarter, Not Harder Available with Beat the GMAT members only code • Award-winning private GMAT tutoring Register now and save up to$200
