GMAT Question Patterns: Absolute ValueWe have gone through the GMAT Prep Tests and OG 13 and analyzed all of the questions to spot the most common patterns. This discussion is dedicated to the types of absolute value problems that could appear on the test. The idea behind this project is to find as many common question patterns as possible for 3 reasons:  Get a higher score  make sure you know how to answer every pattern and you don't miss one of these in your practice
 Save Time  you don't need to solve hundreds of questions; you just need to solve a few questions from each pattern and if you answered them correctly, you can move on
 Peace of Mind  know that you have covered all known question patterns
Background  Most GMAT absolute value problems are encountered in data sufficiency section.
 Both number plugging method and algebra are suitable to solve absolute value questions.
 Usually you get 23 questions on absolute values on the test (based on GMAT Prep CATs)
Typical questions:NOTE:  The questions below are from OG13 and GMAT Prep. There are 6 questions on absolute value in OG13.
 The question patterns are listed from most common to least common.
Pattern #1: Absolute Value and Inequalities.OG13 Practice Questions, question 159If x is an integer, is xx<2^x ?(1) x < 0 (2) x = 10 Discussed HEREIs xy>xy ?(1) y < x (2) xy < 0 Discussed HEREIs x> 1?(1) (x+1) (x  1) > 0 (2) x < 5 Discussed HEREIs x > y?(1) x^2 > y^2 (2) x > y Discussed HEREIf x≠0, is x < 1 ?(1) x^2 < 1 (2) x < 1/x Discussed HERE Pattern #2: Absolute Value and Algebra.OG13 Practice Questions, question 1What is the value of x ?(1) x =  x (2) x^2 = 4 Discussed HEREIf \(x\neq{0}\), then \(\frac{\sqrt{x^2}}{x}=\)A. 1 B. 0 C. 1 D. x E. \(\frac{x}{x}\) Discussed HEREIf x<0, then \(\sqrt{xx}\) is:A. x B. 1 C. 1 D. x E. \(\sqrt{x}\) Discussed HEREIs \(\sqrt{(x3)^2}=3x\)?(1) \(x\neq{3}\) (2) \(xx >0\) Discussed HERE Pattern #3: Must ot Could be true questions with Absolute Value.OG13 Practice Questions, question 14If \(y\frac{1}{2} < \frac{11}{2}\), which of the following could be a value of y?(A) 11 (B) 11/2 (C) 11/2 (D) 11 (E) 22 Discussed HEREIf x > 3, which of the following must be true?
I. x > 3 II. X^2 > 9 III. x1>2A. I only B. II only C. I and II only D. II and III only E. I, II, and III Discussed HERE Pattern #4: Absolute Value and Distance.OG13 Practice Questions, question 24Of the five coordinates associated with points A, B, C, D, and E on the number line above, which has the greatest absolute value?(A) A (B) B (C) C (D) D (E) E Discussed HEREOG13 Practice Questions, question 143Which of the following inequalities is an algebraic expression for the shaded part of the number line above?(A) x <= 3 (B) x <= 5 (C) x  2 <= 3 (D) x  1 <= 4 (E) x +1 <= 4 Discussed HEREIf s and t are two different numbers on the number line, is s + t = 0 ? (1) Distance between s and 0 is the same as distance between t and 0 (2) 0 is between s and t Discussed HERE Pattern #5: Min/Max and Absolute Value.OG13 Practice Questions, question 51If y is an integer, then the least possible value of 23  5y is(A) 1 (B) 2 (C) 3 (D) 4 (E) 5 Discussed HERE Theory on absolute value is HERE. All OG13 questions with solutions are HERE. PS absolute value questions are HERE. DS absolute value questions are HERE. 700+ absolute value questions HERE.

Will publish in a while. hey Bunuel , Many thanks for this wonderful post and can't thank enough for your "tips , approach and concepts" discussed in each question. My sincere request , please add the link in your signature....may be under new section called "Concept and Practice" as you are currently having "Resources" and "Collection of Questions". Are there any other threads for GMAT Patterns? thanks and regards

Hi Bunuel, Where can I find all other patterns that have been identified by you or others (if any you are aware of)? Thanks in advance for our help. Regards.

Very helpful. Are there common "strategy patterns" or "solution patterns" to glean from these question patterns?
