Therefore, for the month with 13 kg consumption of sugar, it exceeds the typical monthly consumption by: (13 - 11)/11 x 100 = 2/11 x 100 = 18.18 percent Answer: B _________________ Scott Woodbury-Stewart Founder and CEO ### GMAT/MBA Expert Elite Legendary Member Joined 23 Jun 2013 Posted: 10109 messages Followed by: 494 members Upvotes: 2867 GMAT Score: 800 Hi All, We're told that the usage of sugar of a family of 3 adults and 2 children was 13 kg in a certain month and the monthly AVERAGE usage of sugar for an adult is 3 kg and for a child is 1 kg. We're asked by what percent THIS specific month’s sugar consumption was more or less than the typical usage. The wording of this question is 'clunky', but the intent is to test us on the Percentage Change Formula: Percent Change = (New - Old)/(Old) = Difference/Original With 3 adults and 2 children, the AVERAGE monthly usage would give us a total of (3)(3) + (2)(1) = 11 kg of sugar. This month, the total is 13 kg though, which is clearly an INCREASE. The percent change is (13 - 11)/11 = 2/11 = a little more than 18% Final Answer: B GMAT assassins aren't born, they're made, Rich _________________ Contact Rich at Rich.C@empowergmat.com • Free Trial & Practice Exam BEAT THE GMAT EXCLUSIVE Available with Beat the GMAT members only code • 1 Hour Free BEAT THE GMAT EXCLUSIVE Available with Beat the GMAT members only code • Free Practice Test & Review How would you score if you took the GMAT Available with Beat the GMAT members only code • 5 Day FREE Trial Study Smarter, Not Harder 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 • Free Veritas GMAT Class Experience Lesson 1 Live Free Available with Beat the GMAT members only code • Award-winning private GMAT tutoring Register now and save up to$200
