Width = 20 Length = 30 Width of the rectangle is decreased by x% implies new width = 20 - x% of 20 = 20(1 - x/100) Length of the rectangle is increased by y% implies new length = 30 + y% of 30 = 30(1 + y/100) New area of rectangle = 20(1 - x/100) * 30(1 + y/100) = 600(1 - x/100)(1 + y/100) = 600(1 - x/100 + y/100 - xy/10000) = 600 - 6x + 6y - 3xy/50 = 6(100 - x + y) - 3xy/50 The correct answer is A. _________________ Anurag Mairal, Ph.D., MBA GMAT Expert, Admissions and Career Guidance Gurome, Inc. 1-800-566-4043 (USA) Join Our Facebook Groups GMAT with Gurome https://www.facebook.com/groups/272466352793633/ Admissions with Gurome https://www.facebook.com/groups/461459690536574/ Career Advising with Gurome https://www.facebook.com/groups/360435787349781/ Master | Next Rank: 500 Posts Joined 15 Feb 2012 Posted: 109 messages Followed by: 2 members Upvotes: 8 IMO E, E, A _________________ Ankita Legendary Member Joined 14 Apr 2009 Posted: 976 messages Followed by: 12 members Upvotes: 49 Test Date: 18.10.2012 Target GMAT Score: 760 GMAT Score: 700 For second question, IMO A. _________________ Regards, Pranay • Award-winning private GMAT tutoring Register now and save up to$200
