securitygeek Posted May 4, 2005 Author Share Posted May 4, 2005 Thanks guys! I take GMAT on saturday. I think I should be okay if I get 600ish to get into the program I am looking at. If I get the score I want in my first attempt and get into this program I am looking at (I will know in 2-3 weeks after my exam), I have promised myself that I will donate all my GMAT prep material to all you fellow testmagicians. Please keep your fingers crossed for me. Thank you!:luck2: Link to comment Share on other sites More sharing options...

rv_blitz Posted May 18, 2005 Share Posted May 18, 2005 Security Geek, This is a great compilation. An alternative way 2 solve this problem. 31. If Bob and Jen are two of 5 participants in a race, how many different ways can the race finish where Jen always finishes in front of Bob? Ans : Total number of ways of arranging 5 participants = 5! = 120. In, half of these arrangements Jen will finish ahead od Bob . So, no of arrangements = 120/2 = 60 Link to comment Share on other sites More sharing options...

rv_blitz Posted May 19, 2005 Share Posted May 19, 2005 54. Two people walked the same distance, one person's speed is between 25 and 45,and if he used 4 hours, the speed of another people is between 45 and 60,and if he used 2 hours, how long is the distance? A.116 B.118 C.124 D.136 E.140 Soln : A Let A be the person walking with speed between 25 and 45. 25 Let B be the person walking with speed between 45 and 60. 45 TimeA = time taken by A to cover the required distance d = 2 hrs. TimeB = time taken by B to cover the same distance d = 4hrs. As the distance is same. (TimeA/TimeB)=(SpB/SpA)=4/2=2/1. There fore the possible combinnations for SpA,SpB based on the constraints = (25,50) (26,52) (27,54) (28,56) (29,58) (30,60) As , we know time taken by A = 4hrs, the only answer that matches the option is 29*4=116. Hence , A. Link to comment Share on other sites More sharing options...
forthegmat Posted May 20, 2005 Share Posted May 20, 2005 I am getting a different answer to question#1. Sum of even numbers between 1 and n = 2 + 4 + ...+ (n-1) = 2(1 + 2 + ..(n-1)/2) = (n-1)(n+1)/4 So we get the equation: (n-1)(n+1)/4 = 79*80 which reduces to (n-1)(n+1) = 158*160 from which we get n = 159.

The sum of the even numbers between 1 and n is 79*80, where n is an odd number, then n=? n*(n+1) = 79 * 80 ==> n =79:D Link to comment Share on other sites More sharing options...
