CAT Logical Reasoning Syllabus and Preparation Tips

CAT Logical Reasoning Syllabus and Preparation Tips: CAT’s Logical Reasoning and Data Interpretation (LRDI) section has undergone significant changes in recent years. Previously, the LRDI section had an equal number of questions from LR and DI. However, logical based DI sets have now replaced calculation intensive DI sets. This shift has made the LRDI section more focused on logical reasoning. This article will be divided into two parts: the Logical Reasoning Syllabus for CAT and tips on how to prepare for CAT Logical Reasoning.

Many aspirants are curious about the syllabus for LRDI. The LRDI section does not have defined problems like other sections. Instead, it consists of a passage with a set of numerical or logical conditions, followed by four to five questions.

The difficulty level of the questions varies, ranging from easy to very difficult depending on how easily one can arrive at the answers. While it is difficult to define the syllabus, we can categorize the problems based on the trend of the last few years. Here are some frequently found CAT Logical Reasoning Syllabus and Preparation Tips question sets in CAT:

CAT Logical Reasoning Syllabus

Logical Reasoning Type 1 – Fixing the missing numbers: CAT has replaced traditional calculation intensive DI sets with sets that have missing numbers. Students are expected to fill in these numbers by carefully studying the logical conditions. Once the numbers have been fixed, calculating the final step towards finding the right answer. These types of questions have appeared in recent CAT papers.

Logical Reasoning Type 2 – Breaking of numbers: The difference between “fixing the number” and “breaking the numbers” is the approach. “Fixing the numbers” involves logically breaking down conditions and using given data to arrive at figures. On the other hand, “breaking the numbers” requires using mathematical concepts to derive the correct answer by distributing numbers based on given conditions. This type of question often requires more calculations.

Logical Reasoning Type 3 – Games and Tournaments: Games and Tournaments sets were common in the traditional CAT exams but have not appeared in recent years. However, it is still important for aspirants to familiarize themselves with this category as the techniques learned can be applied to other sets. These types of sets help develop stamina and focus.

Logical Reasoning Type 4 – Maxima Minima set theory / Venn diagram: Maxima Minima set theory has been a favorite area of CAT LRDI. These questions are known for their high difficulty level, but are less time consuming than other types. Students need to be careful in approaching these sets to avoid mistakes.

Logical Reasoning Type 5 – Data arrangements/matrix based (tabular form): Matrix based sets are the conventional type that we are familiar with. They are often easier for students and should be practiced extensively to improve accuracy. Typically, CAT includes at least one or two sets of this kind.

Logical Reasoning Type 6 – Linear Arrangement sets: Linear arrangement sets are usually not very difficult and have not been seen in recent CAT papers. However, it is still important for aspirants to practice these sets as they are generally considered easy.

Logical Reasoning Type 7 – Circular Arrangement sets: Circular arrangement sets are slightly more challenging and require a different approach compared to linear sets. While they have not appeared frequently in recent CAT papers, the concepts learned from these sets can be applied to other types.

Logical Reasoning Type 8 – Sequencing and arrangement: Sequencing and arrangement sets are not difficult but require caution and careful reading. Negligence can lead to incorrect answers. These sets were seen in good numbers in CAT 2017 and should be expected in CAT 2018.

Approaching the Logical Reasoning section of CAT requires a customized method as each set is unique and may require a different approach. However, here are a few general steps that students should follow before attempting any LRDI set:

1. Scan the entire set, including the questions.
2. Identify the number of variables and determine if any are too confusing or numerous to tackle immediately.
3. If the variables are manageable, create a structure for the set on paper.
4. Identify critical data/conditions and note them down.
5. Fill in direct data from conditions and represent the data visually.
6. Combine conditions to interpret the possibilities and add the information to the structure.
7. Revisit conditions if necessary to narrow down possibilities and fine tune the structure.
8. In case of insufficient conditions, analyze the questions to see if some can be answered. Incorporate these conditions with existing ones to determine the answers.

Developing good question-picking skills is crucial. Students can increase their chances of reaching a high percentile in this section by selecting the right sets and not wasting time on difficult ones.

The best source for practicing logical reasoning questions is past year CAT papers. Regardless of the number of mocks solved, it is important to become familiar with previous CAT LRDI sets. Additionally, solving as many past year mocks as possible will expose students to a variety of sets and questions.

If you’re looking for online resources, Bodhee Prep’s LRDI online course is recommended. It offers a good number and variety of LRDI sets at a low price, and video solutions accompany each set.

Practice is key to performing well in the LRDI section of CAT.
