Welcome to the another installment of Workbook Wednesdays. Thanks again to Manhattan GMAT for supplying today’s question and (more importantly) tomorrow’s answer! Just like last week, this problem mimics the most advanced quantitative problems on the exam, the type of problem you will see if you are scoring around 700 or higher.
Question
If x and n are positive integers, is n = 1?
(1) The sum of n consecutive integers, starting at x, is divisible by xn.
(2) The product of n consecutive integers, starting at x, is divisible by x^n.
(A) Statement (1) ALONE is sufficient to answer the question, but statement (2) alone is not.
(B) Statement (2) ALONE is sufficient to answer the question, but statement (1) alone is not.
(C) Statements (1) and (2) TAKEN TOGETHER are sufficient to answer the question, but NEITHER statement ALONE is sufficient.
(D) EACH statement ALONE is sufficient to answer the question.
(E) Statements (1) and (2) TAKEN TOGETHER are NOT sufficient to answer the question.
Get out your pencils and scratch paper, and be sure to check back tomorrow for an in depth look at the answer!
