1 says A+C is 2B Insufficient since A B and C can be non integers too 2 says A B and C are integers Insufficient But 1 and 2 together gives ABC as consecutive integers with B as the middle number. Sent from my ONEPLUS A3003 using GMAT Club Forum mobile app

(1) CB = AB (2) A, B, and C are all integers St 1: CB = AB. Hence A = C. therefore they are not consecutive integers. ANSWER St 2: INSUFFICIENT as no further data has been provided Option A

Please check your calculation again. Statement (1) is => CB = AB => C = A  B + B = A i.e. C = A. Hence A, B, and C are not consecutive integers as A & C are same. Answer  Option A

(1) CB = AB (2) A, B, and C are all integers 1. rewrite it as CB+B=A or C=A  we know for SURE that A,B,C are not consecutive. moreover, we don't care if they are integers or not  we definitely know that A=C, and in this case, there is no way for them to be consecutive integers. 2. doesn't tell us much

(1) CB = AB (2) A, B, and C are all integers VERITAS PREP OFFICIAL SOLUTION:Solution: A Statement (2) is insufficient on its own, as it allows for the integers to be spread across the entire number line; INSUFFICIENT. If we add B to both sides of statement (1), however, we learn that C = A. If C = A, the integers cannot be consecutive, as at least two of them equal each other; SUFFICIENT, (A).
