3. Logic-Based: In the CAT exam, sometimes charts are used to give data in ranges or with conditions where it is not possible to find the exact data. In such cases, the candidate is usually asked to find a number which can be arrived at by fulfilling the need to maximize or minimize the number. The candidate needs to use strong logic to deduce an answer to these questions.
