Thanks for a lot of inspirations
good job mam...thnx..
can we take this question as fill-up also, like CAT has also introduced as in new DI pattern question.

Mentioning this on my comment is not a good idea, a better idea would be change the title of the course. Considering the fact that you scored 98+ percentile, you have better understanding than me, but still a suggestion.
1. Data Intenpretation Based on Tables INTRODUCTION

2. About Me .I hold a B.E degree in Electronics and Communication Engineering. CAT, 17: DI & LR-98.29 %ile I would take you through the DI & LR lessons for CAT . Not all are born Einstein's but trust me with hard work and dedication we can together make it possible

3. Contribution of the topic Total Questions from DI & LR section: 32 All questions were in sets form, wherein each set comprised 4 questions. 16 Questions (i.e., 4 sets) on DI 16 Questions i.e., 4 sets) on LR Data Interpretation(DI) .Of the 4 sets on DI, 1 set i.e., 4 questions may be based on Tables Hence, we can say 25% of DI may be cleared if we thoroughly prepare this topic. NOTE: This analysis is based on previous year papers

4. What is Data Interpretation? Data Interpretation or Data Analysis, as the name suggests, is all about data. Looking at life scientifically, we can say that life is all about DATA. It is all around us, almost everything is accompanied with data. From sales reports to trends to budget planning to almost every single operation, some calculations or the other are required. In this section, we explore these calculations The basic idea that operates behind these questions is to test a candidate on his ability to make decisions and establish what would be the best recourse in different situation. Each set of question generally consist of multiple conditions and one is supposed to use these clues to solve the questions.

5. Structure of Questions In the question, Data may be presented in any of the following form: 1. Tables 2. Bar Charts 3. X-Y Charts 4. Pie Charts 5. Cases (Representing Data) We need to solve it using the information given. Note: In this course we are going to study Tables in detail.

6. Tables Tables are basically "a chart of facts and figures shown in horizontal rows and vertical columns. They are one of the most versatile methods of systematic representation of quantitative data. Since, the amount of data that can be represented in a table is much higher than any other form. In fact, the data represented in any other form can be converted to a table for ease. The following exercise will help you to clearly understand tables and the kinds of questions that might be created on tables. What flavor of ice cream would you pick?

7. Key Skills Involved I. Read the figures given closely. II. Do not over approximate just to simplify your task. III. DO NOT ASSUME information that is not given in the questions Note: *Data Interpretation revolves around Arithmetic and calculation speed *Focus and Practice is all you need.

8. Example i: Directions : Following table gives the population of a locality from 1988 to 1992. Read the table and answer the questions. Years Men Women Children Total Increase (+) or decrease () over preceding year 1988 1989 1990 1991 1992 60387 62516 63143 65104 146947 70391 (11630) 20314 21560 23789 153922 69395 (5337) 71274 659935 160998

9. Answer the following: Q1. The number of children in 1988 is: (1) 31236 (2) 12549.1 (3) 14546 (4) 21456 Workspace: Years en WomenChildrenTotal Increase (+)or decrease (- over precedingyear 146947- 1988 65104 1989 70391 1990 |- 1991 69395 1992 71274 60387 62516 63143 +(11630) 153922 20314 21560 23789160998 (5337) 659935
