Data Interpretation is a significant section of the CAT (Common Admission Test). It tests how well a candidate is able to analyze, interpret, and conclude based on data. DI questions may be presented in the form of tables, pie charts, bar graphs, or caselets. They require the use of analytical mind, mathematical abilities, and efficient management of time. DI in recent years in CAT examinations has been more logical than calculations. That is to say that it is highly necessary that students prepare strategically for this section.
For the majority of students, DI is both difficult and a scoring section, within the framework of the time constraint. Top-scoring students can understand patterns quickly, sift out the unimportant information, and use the proper logic. Working with multiple sets of DI familiarizes students with diverse formats, boosts accuracy, and boosts confidence in taking the actual test.
In this article, we have provided more than 100 chosen Data Interpretation questions of CAT with accurate solutions. The questions vary in types and levels, providing students with a complete practice set. If you are a beginner to this or you wish to enhance your skills, this set will get you ready to face CAT DI.
