CAT is one of the most difficult exams worldwide and has a very low acceptance rate of 2 percent. To get a good overall score, it is important to master all the topics and sections of the exam. Data Sufficiency, a very important topic of the exam, tests the ability of a candidate to determine whether a given set of data is sufficient to answer the question given. The candidates are not required to find the solution to the question.

Data Sufficiency questions of the CAT are included in the data interpretation section and are challenging for every candidate as they have a unique format. All Data Sufficiency problems have the same structure. They comprise three elements:

- A stem
- Two statements
- The answer choices

The two statements are labeled as I and II. Each of the two statements entails certain information that may or may not be related to the problem. The candidate has to determine whether the information provided in the statements, either I or II or both I and II are sufficient to solve the problem. The question stem may carry important information and requires you to read between the lines. Statement II should be read independently of Statement I. The answer should satisfy both the statements. In every question, the answer choices are exactly the same; therefore, it is important to remember the answer choices to help you save time during the exam.

**Important Data Sufficiency tips:**
