In these questions ,you are to classify each problem according to the five fixed answer choices, rather than find s solution to the problem. Each problem consists of a question and two statement. You are to decide whether the information in each statement slone is sufficient to answer the question or if neither is, whether the information in the two statements together is sufficent | y fa c 5 Data Sufficiency In these questions you are to classify each problem according to the five fixed answer choices rather than find a solution to the problem . Each problem consists of a question and two statements You are to decide whether the information in each statement alone is sufficient to answer the question-or if neither is whether the information in the two statements together is sufficient The following pages include test-taking strategies sample questions and a detailed explanation of every problem These explanations present possible problem-solving strategies for the examples Test-taking Strategies for Data Sufficiency 1 Do not waste valuable time solving a problem you are only to determine whether sufficient information ts given to solve the problem First consider statement 1 and statement 2 separately and determine whether each alone gives sufficient information to solve the problem Be sure to disregard the information given in statement 1 when you evaluate the information given m statement 2 If either or both of the statements give sufficient information to solve the problem click on the oval corresponding to the description of which statement s give sufficient information to solve the problem If not consider the information m both statement 1 and statement 2 Then click on the oval corresponding to the description of whether the statements TOGETHER give sufficient information to solve the problem 2 Remember that when you are determining whether there is sufficient information to answer a question of the form Wjiat is the value df jJ9 the information given must be sufficient to find one and only one value for y Being able to determine minimum or maximum values or an answer of the form y x 2 is not sufficient because such answers constitute a range of values rather than the value of y 3 When geometric figures are involved be very careful not to make tin warranted assumptions based on the figures Figures are not necessarily drawn to scale they .
