1. Top 10 Myth Busters Before you start your final preparation for CAT, you should understand DI Section thoroughly. Take this Quiz to test your understanding of CAT DI Section.

Statements What you think about

it True or False?

DI & LR are becoming more and more complex in CAT True • False

1 wrong interpretation doesn’t mean losing more then 10 marks! True • False

DI is always more important than LR in CAT preparation True • False

It’s all about Calculations honey... True • False Best way for DI/LR Take a book of puzzles and finish it in a week.. True • False Ram sits here and shyam there.. I love puzzles they are easys True • False Tables, charts, DS and Puzzles, Should be 2 days job! True • False I just run through DI questions… Its easy! True • False Instructions are always boring.. I skip them True • False DI is more about logic... you don’t need Vedic maths? True • False Answers: Count your score by giving 1 mark for each FALSE you circled in the test above. Answer to all the above questions is FALSE. Score Analysis

Your Score Analysis

8 + right You have very good understanding of CAT Environment and are well prepared to take the CAT headon! For you CATking workshop will be about learning shortcuts and techniques only.

6 – 8 right You have got decent score. But still need a better understanding of CAT before you sit for the exams. CATking workshop will provide you an overall understanding of CAT along with shortcuts and techniques.

5 & less

You need more understanding of the dynamics of CAT. Going for CAT half prepared can be suicidal and can seriously hamper your chances to get into top B-school. Joining CATking will help you develop the right attitude and skills for CAT along with shortcuts and techniques.




10 Myths Explained Solutions:

Myth no. Statements

1 No the level of DI & LR remains same in CAT over the years

2 Yes, 1 wrong interpretation means you will lose more then 10 marks!

3 Logical Reasoning & DI are equally important in CAT preparation

4 It’s NOT all about Calculations honey... focus of DI/LR is shifted to Logic based DI

5 Take a book of puzzles and finish it in a week.. doing this will make you bored

6 Ram sits here and shyam there.. Puzzles are now more difficult then they used to be

7 DI / LR aptitude cannot be improved over night

8 DI / LR questions are not to be done quickly rather give time to each question set

9 Its very important to focus on Instructions as they are tricky..

10 30% of DI is still based on calculations so master your Vedic Maths skills.

1. Myth: DI / LT Section is becoming complex: Reality: My old friends DI & LR Explanation: DI & LR in CAT are still old sweet type of questions, There is no rocket science to understand type of DI questions. You have already done that million of times. The type of questions which comes in DI are Tables, Long Tables, Bar Charts and Line Charts are still same and with same complexity. Same goes for LR, the type of puzzles still remains same – Matrix based, Investment, Arrangement and Selection based. 2. Myth: DI is more important than LR in CAT Reality: Era of Logic Reasoning Explanation: DI is no longer dominating in CAT. In 2006 & 2008 DI/LR section was more based on Logical reasoning then DI, with more then 50% of the paper dedicated to LR only. We doubt why students were surprised to see more of LR questions. From last 5 years DI/LR section is shifted from Calculations to Logical based questions. Rest of the Myths will be discussed with examples in the Workshop.

2. Pre workshop Homework We expect you to do some homework before you come for the workshop. This will make sure that we all are on the same page and will be very easy for you to grasp the shortcuts and strategies taught in the workshop. 1. Back to basics You will understand the shortcut better if you know the ‘longcut’ of doing the problem. So take any book you have and run though the basics (Introductions and formulas) of all the chapters. Step 1: Take any book - your coaching institute’s material book or independent books like Arun sharma. Step 2: Take a chapter, say Chapter 1 Numbers, go through and have clear understanding of the basics like concepts, formulas, theorems and other topics) Step 3: Make notes of all the basics like we used to do in school days Check list for 1 & 2.

Topic 14

Topic 15 2. Solved examples Best way to understand the basics in a practical way is to solve the solved examples of a topic from books. So take any book you have (coaching material of other books) and run though the basics (Introductions and formulas) of all the chapters. Step 4: Reinforce the basics and concepts learned by solving the 20 odd solved examples given in starting of each book. Step 5: Make notes of the practical applications of each concept.

CATking’s 4 step approach




3. Building blocks - Mocks & Test Mocks are best way to simulate your D-Day performance. We recommend you to take 5 Sectional tests and 5 full length mocks. If you have joined a coaching institute then you might have done this otherwise download last 5 years CAT papers from www.mbageeks.com and solve them as 5 mocks. Step 6: Take a minimum of 5 sectional tests and analyse your mistakes Step 7: Take 5 full length mocks and analyse your performance Checklist for 3:

Answer Questions 4 to 8 on the basis of the information given below: CAT 2006 Two traders, Chetan and Michael, were involved in the buying and selling of MCS shares over five trading days. At the beginning of the first day, the MCS share was priced at Rs 100, while at the end of the fifth day it was priced at Rs 110. At the end of each day, the MCS share price either went up by Rs 10, or else, it came down by Rs 10. Both Chetan and Michael took buying and selling decisions at the end of each trading day. The beginning price of MCS share on a given day was the same as the ending price of the previous day. Chetan and Michael started with the same number of shares and amount of cash, and had enough of both. Below are some additional facts about how Chetan and Michael traded over the five trading days. • Each day if the price went up, Chetan sold 10 shares of MCS at the closing price. On the other hand,

each day if the price went down, he bought 10 shares at the closing price. • If on any day, the closing price was above Rs 110, then Michael sold 10 shares of MCS, while if it was

below Rs 90, he bought 10 shares, all at the closing price. 4. If Chetan sold 10 shares of MCS on three consecutive days, while Michael sold 10 shares only once during the five days, what was the price of MCS at the end of day 3? (1) Rs 90 (2) Rs 100 (3) Rs 110 (4) Rs 120 (5) Rs 130 5.

Some costs change almost in direct proportion to the change in volume of production, while ‘others do not follow any obvious pattern of change with respect to the volume of production and hence are considered fixed. Using the information provided for the year 2006 as the basis for projecting the figures for the year 2007, answer the following questions. 14.
