Charts
These types of questions involve data interpretations, and also, there are different types of charts present, such as pie, line, bar, spiderwebs, etc. In the past few years, at least one question has been given on this topic.
Tables
There will be a chance to give these types of table-based sets in the CAT exam. There is a chance of giving the tables in various formats such as sudoku, ratio & proportions, liner equation, permutations & combinations, etc.
Arrangements
These types of questions come under logical reasoning. Arrangement questions are designed to test the analytical mindset of the students that are taking the CAT exam, which is the most essential skill for the corporate world. Check out the below sample question from arrangements of CAT DILR.
Sample Question:
A shopping mall has a large basement parking lot with parking slots painted in it along a single row. These slots are quite narrow; a compact car can fit in a single slot, but an SUV requires two slots. When a car arrives, the parking attendant guides the car to the first available slot from the beginning of the row into which the car can fit.
For our purpose, cars are numbered according to the order in which they arrive at the lot. For example, the first car to arrive is given a number 1, the second a number 2, and so on. This numbering does not indicate whether a car is a compact or an SUV. The configuration of a parking lot is a sequence of the car numbers in each slot. Every single vacant slot is represented by the letter V.
For instance, suppose cars numbered 1 through 5 arrive and park, where cars 1, 3 and 5 are compact cars and 2 and 4 are SUVs. At this point, the parking lot would be described by sequences 1, 2, 3, 4, and 5. If cars 2 and 5 now vacate their slots, the parking lot would now be described as 1, V, V, 3, 4. If a compact car (numbered 6) arrives, followed by an SUV (numbered 7), the parking lot would be described by the sequence 1, 6, V, 3, 4, 7.
Answer the following questions INDEPENDENTLY of each other.
Suppose that car 4 is not the first car to leave and that the sequence at time between the arrival of car 7 and car 8 is V, 7, 3, 6, 5. Then which of the following statements MUST be false?
1. Car 2 is a Compact.
2. Car 7 is a Compact.
3. Car 4 is an SUV.
4. Car 6 is a Compact.
Solution: Here, we can see that cars 3 and 5 are still in their position. Thus car 4 was not the first car to leave. Either 1 or 2 left before 4. Let’s say only car 2 left before car 4. Now, supposedly if car 2 is an SUV, car 6 was parked in that lot. Thus car 2 and car 7 are compact cars. Option 4 is correct.
