GMAT Data Sufficiency (DS) Overview<\/strong><\/h3>\n

Data Sufficiency is a unique question type in the GMAT Quantitative section<\/strong> designed to test your ability to analyze information and determine whether given data is sufficient to answer a question. Instead of solving for an exact answer, you assess whether<\/strong> the provided statements are enough to find a solution.<\/p>\n

GMAT Data Sufficiency Question Format<\/strong><\/h3>\n

Each question consists of:<\/p>\n

    \n
  1. A question stem<\/strong> (the problem to be solved).<\/li>\n
  2. Two statements<\/strong> labeled (1) and (2), providing additional information.<\/li>\n
  3. Five answer choices<\/strong>, always the same:<\/li>\n<\/ol>\n\n\n\n\n\n\n\n\n\n
    Answer Choice<\/th>\nMeaning<\/th>\n<\/tr>\n<\/thead>\n
    A<\/strong><\/td>\nStatement (1) alone<\/strong> is sufficient, but (2) is not.<\/td>\n<\/tr>\n
    B<\/strong><\/td>\nStatement (2) alone<\/strong> is sufficient, but (1) is not.<\/td>\n<\/tr>\n
    C<\/strong><\/td>\nBoth<\/strong> statements together are sufficient, but neither alone is.<\/td>\n<\/tr>\n
    D<\/strong><\/td>\nEach statement alone<\/strong> is sufficient.<\/td>\n<\/tr>\n
    E<\/strong><\/td>\nEven both statements together<\/strong> are not sufficient<\/strong> to answer the question.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

    GMAT Data Sufficiency Strategy<\/strong><\/h3>\n
      \n
    1. \n

      Understand the Question Type<\/strong><\/p>\n

        \n
      • Is it a yes\/no<\/strong> question? (e.g., “Is x positive?”)<\/li>\n
      • Is it a value-based<\/strong> question? (e.g., “What is the value of x?”)<\/li>\n<\/ul>\n<\/li>\n
      • \n

        Evaluate Statement (1) Alone<\/strong><\/p>\n

          \n
        • Determine if it is enough to answer the question.<\/li>\n
        • If sufficient, eliminate B, C, and E.<\/li>\n<\/ul>\n<\/li>\n
        • \n

          Evaluate Statement (2) Alone<\/strong><\/p>\n

            \n
          • If sufficient alone, eliminate A and C.<\/li>\n<\/ul>\n<\/li>\n
          • \n

            Combine the Statements (if necessary)<\/strong><\/p>\n

              \n
            • If neither alone is sufficient, check if together they answer the question.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n

              Example GMAT Data Sufficiency Question<\/strong><\/h3>\n

              Question:<\/strong> What is the value of xx<\/span>x<\/span><\/span><\/span><\/span>?

              \n(1) x2=16x^2 = 16<\/span>x<\/span>2<\/span><\/span><\/span><\/span><\/span><\/span><\/span>=<\/span><\/span>16<\/span><\/span><\/span><\/span>

              \n(2) \u2223x\u2223=4|x| = 4<\/span>\u2223<\/span>x<\/span>\u2223<\/span>=<\/span><\/span>4<\/span><\/span><\/span><\/span><\/p>\n

              Step-by-step Solution<\/strong><\/h4>\n
                \n
              • \n

                Statement (1) Alone:<\/strong> x2=16x^2 = 16<\/span>x<\/span>2<\/span><\/span><\/span><\/span><\/span><\/span><\/span>=<\/span><\/span>16<\/span><\/span><\/span><\/span><\/p>\n

                  \n
                • Possible values: x=4x = 4<\/span>x<\/span>=<\/span><\/span>4<\/span><\/span><\/span><\/span> or x=\u22124x = -4<\/span>x<\/span>=<\/span><\/span>\u2212<\/span>4<\/span><\/span><\/span><\/span>.<\/li>\n
                • Since there are two possible values<\/strong>, NOT sufficient<\/strong>. \u2192 Eliminate A and D.<\/strong><\/li>\n<\/ul>\n<\/li>\n
                • \n

                  Statement (2) Alone:<\/strong> \u2223x\u2223=4|x| = 4<\/span>\u2223<\/span>x<\/span>\u2223<\/span>=<\/span><\/span>4<\/span><\/span><\/span><\/span><\/p>\n

                    \n
                  • Possible values: x=4x = 4<\/span>x<\/span>=<\/span><\/span>4<\/span><\/span><\/span><\/span> or x=\u22124x = -4<\/span>x<\/span>=<\/span><\/span>\u2212<\/span>4<\/span><\/span><\/span><\/span>.<\/li>\n
                  • Again, not a unique value<\/strong> \u2192 NOT sufficient<\/strong>. \u2192 Eliminate B.<\/strong><\/li>\n<\/ul>\n<\/li>\n
                  • \n

                    Combining Both Statements:<\/strong><\/p>\n

                      \n
                    • Both give the same information<\/strong>: xx<\/span>x<\/span><\/span><\/span><\/span> is either 44<\/span>4<\/span><\/span><\/span><\/span> or \u22124-4<\/span>\u2212<\/span>4<\/span><\/span><\/span><\/span>.<\/li>\n
                    • Still not a single unique value.<\/li>\n
                    • Insufficient.<\/strong><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n

                      Final Answer:<\/strong> E<\/strong> (Even both statements together are not sufficient).<\/p>\n

                      GMAT Data Sufficiency Tips<\/strong><\/h3>\n

                      \u2705 Don\u2019t solve completely<\/strong>\u2014just determine sufficiency.

                      \n\u2705 Check for hidden constraints<\/strong> in absolute values, inequalities, and number properties.

                      \n\u2705 Memorize answer choices<\/strong> to save time.

                      \n\u2705 Watch for Yes\/No traps<\/strong>\u2014getting both \u201cyes\u201d and \u201cno\u201d means insufficient.

                      \n\u2705 Think algebraically and conceptually<\/strong> instead of plugging in numbers.<\/p>\n
