![]() (2) a and b are positive integers such that (a + b)2 - (c + d)2 = 0. (1) c and d are negative integers such that (a + b)3 - (c + d)3 = 0. What is the probability of A/B if A and B are mutually exclusive events?.(1) The average of the square of n and 'n' is 6. What is the value of the non-positive integer n?.Using the data given in the statements plus your knowledge of mathematics and every-day facts (such as the number of days in January or the meaning of counterclockwise), you must indicate one of the following answer choices:Ī) if statement (1) alone is sufficient and statement (2) alone is not sufficient to answer the question.ī) if statement (2) alone is sufficient and statement (1) alone is not sufficient to answer the question.Ĭ) if statements (1) and (2) together are sufficient but neither statement alone is sufficient to answer the question.ĭ) if each statement alone is sufficient to answer the question.Į) if both the statements (1) and (2) together are not sufficient to answer the question and additional data specific to the problem is needed You have to decide whether the data given in the statements are sufficient for answering the question. The GMAT Quantitative section measures your ability to reason quantitatively, solve math problems, and interpret graphical data. Hence the approach for these questions should be different and lot of practice and coaching are required.Įach of the problems on data sufficiency below consists of a question and two statements, labelled (1) and (2), in which certain data is given. GMAT Official Advanced Questions Your GMAT Official Prep collection of only hard GMAT questions from past exams. We need to find if the given information is enough to solve a problem. In Data Sufficiency (DS), there is no need to find the answer. In Problem Solving, we need to solve a given problem and find the answer. Though Indians do well in Problem solving, most of them struggle with Data Sufficiency as this is a new question type to most of them. ![]() ![]() What is the median of these temperatures?
