GMAT-HELP Posted July 20, 2006 Share Posted July 20, 2006 number = 5n Stmt 1: 4x+3 => 5n = 4x+3 => (6x-2x+3)/6 => remainder will vary with the value of x => x can be 3,8,13,18, 23 and so on => number = 15, 35, 55... => remainder can be 3, 5, 1... Insufficient Stmt 2: 12x+3 => 5n = 12x+3 => (12x+3)/6 always leaves a remainder 3..(number = 15,75,135 and so on) Sufficient Ans B. Quote Link to comment Share on other sites More sharing options...
gjgjgj Posted July 20, 2006 Share Posted July 20, 2006 1) is not sufficient because the number can be 15 or 35 wherein the remainders are 3 and 5 respectively 2) is sufficient because the remainder in every case will be 3. e.g. 15 75 135 Hence the answer is B Quote Link to comment Share on other sites More sharing options...
