CAT 2011 prep: Problem areas in DI&LR and the solutions

5th of May, 2011 Bookmark and Share
For all the to be takers of CAT 2011 who find Data Interpretation and Logical Reasoning section as a big problem area, presents special tips for improving the grasp on this section.
As the first step towards improvement, you need to believe that Data Interpretation and Logical Reasoning is not a Rocket Science which you cannot tackle. The best part about preparing for the DI and LR section is that there are hardly any concepts that you need to know before the test. Also, it is a misconception that DI is all about calculation and number crunching.
Get enough practice
You should get sufficient practice for the Data Interpretation and Logical Reasoning section so that you get comfortable with the section. The section largely tests your reasoning skills (in case of both DI and LR). The same can be acquired/fine-tuned through practice and more practice.
The ideal practice should be to do around three to four Data Interpretation sets daily and about eight to 10 Logical Reasoning questions.
Problems you face while solving DI & LR questions and their solutions
The following are the key problem areas and their solutions:
1. You are getting stuck in a question simply because you tend to spend time reading the caselet. The key is to move on.
2. There are some LR questions in which when you crack the logic you can solve all and the other where you need to solve each questions independently. In most of the cases, the issue would be in the later type of questions. Practice these kinds a little more.
3. Data Interpretation is NOT Data calculation. The focus is on analysis of data. Pick up an article in a business magazine with a lot of data and create your own questions.
The following points should be kept in mind while attempting the questions on DI & LR:
• Take your time and read both the questions and data set carefully. Understand what you are being asked to do before you begin figuring out the information.
• Check the data and types of information required. Be sure that you are looking at the right part of graph or chart i.e., on proper columns or rows or lines.
• Read the parameters listed along with axes and the scale. This is the most important points as generally one assumes standard scale as 1 unit = 100 or 1 unit = 10. Also the scales of two axes might be different.
• The footnotes give the additional information for particular data. This also explains the jargons and lists the formulae that might be needed to solve the questions asked.
• Check the units required. Be sure that your answer is in thousand, millions or whatever it is that the question specifies.
• Improve your ability to work with numbers. You need to be as good as possible in mental calculations viz. additions, subtraction, multiplications, divisions, percentages and ratios. This can only be achieved through consistent practice.
• Solve at least one Data Interpretation set a day to continuously assess and improve your Data Interpretation skills.
Keeping these points and suggestions in mind, you will be able to improve the Data Interpretation and Logical Reasoning section for CAT 2011.
