To crack the almighty entrance test of CAT, the candidates require books that help them to build up the vital concepts that need to be efficiently build up. This aspect of study is very essential that help the candidate to get a high percentile in the CAT exam. Though there are plenty of books that are available in the market, but only few of them will serve the candidates personal purpose. Apart from the stress on the mathematics side, CAT also puts vital stress on verbal ability and data interpretation.

There are lads of books that help the candidates to prepare for CAT and also mentions complete success in the final run, but it lies with the candidates personal mind frame and the suitability o the language and approach of the book. Few books are reliable enough and help to prepare the CAT in an efficient manner.

Though text book help to clear up the vital subjective type questions, few MCQ books also help to build up speed and agility that is basically required in the CAT exam. Few of the books that are recommended for CAT are:

Logical Reasoning TipsTips for Family Chain Problems 

Few things to remember: 1. For solving Logical reasoning questions always try to apprehend the point/inputs by using a graphical reprsentation. 

Eg: for Family-Relationship kind of questions such as1. X is Ys father2. Y is brother of K3. Ks mother in law is M4. N is the only child of M5. P is grand daughetr of Q, who is husband of M For such questions create a tree like representation using your own notations.

Tree structure for above case is shown below:

Try to form your own notations and practice them in mock tests.

Similarly tabular method can be used in other types of LR problems.

Data Interpretation Tips

DI is all about how fast you can comprehend the given data and how fast and accurately you are able to add, multiply subtract, divide and calculate ratios percentages. Below are some of the tips to improve in ths section:

1. Spend about a minute to read the graph and the data properly.

2. Check the range of the options given. You may round off the data for calculations depending upon how far the choices are from each other.

3. Read the footnotes or the legends of the graphs and tables properly. Some people assume that the graphs and figures in the question paper are drawn to scale but this may not be the case.

4. Select the sets which are easy to comprehend and are easy to solve when taking Mocks or the real exam. The only way you will be able to identify easy question is by more practice. Expose yourself to as many questions on DI as possible.

5. Improve your calculation speed specially for calculation of averages and percentages.

6. Needless to say, more practise means more confidence and better result. So practise as much as possible from as many sources as possible.

7. Spend some time on analysis on what kind of mistakes you usually make and try to improve on these areas.

8. During your preparation, after you attempt questions on DI, be it right or wrong check the method used to solve the question by the writer of the book/reference material. Keep a record of all the questions you are not able to attempt correctly in the first go (Just write down Q No. Page No. and Book Name) and attempt these questions again after a few days. 

For Data sufficiency questions you don’t have to actually solve the answers, you just need to find if the data given is enough to solve the questions.

Improve speed and accuracy in Data interpretation/ Data Sufficiency. As there is no substitute for hard work, its obovious that its ur hard work that can only improve your speed and skills.

Practising more questions with setting your time period for exams will surely help u in developing speed.

The more u practise the more quick u will be…

DI: Points to Remember

-> In gleaning data from a chart, graph or table, it's remarkably easy to inadvertently grab your data from the wrong graph, bar, line, etc.

This is the #1 cause of incorrect responses in CAT Data Interpretation. To avoid this blunder, point your finger to the data you want; put your finger directly against the question paper and keep it there until you're sure you're looking at the right part of the right chart or graph.

-> Check to see if the question asks for an approximation. If so, you can safely estimate numbers by rounding off.

CAUTION: When rounding off fractions, round the numerator and denominator in the same direction (either up or down); otherwise you'll distort the value of the fraction.Don't confuse percentages with raw numbers. Always ask yourself which type of number the chart or graph is providing, and which type the question is asking for.

-> It's okay to rely on visual approximations when it comes to reading bar graphs and line charts. The test-makers are not out to test your eyesight.

So if two or more answer choices come very, very close to your solution, rest assured that you needn't estimate values more precisely. Instead, go back to square 1; you've made some other mistake along the way.

-> Take 15-30 seconds right up front to assimilate and make sense of the chart, graph, or table—and be sure to read all the information around it.

(You might need to scroll vertically to view all the information.) Get a sense for what the variables are and how they relate to one another—before you tackle the questions.

Tables, Charts, and Graphs (Data Interpretation)

Graphs and charts show the relationship of numbers and quantities in visual form. By looking at a graph, you can see at a glance the relationship between two or more sets of information. If such information were presented in written form, it would be hard to read and understand.

Here are some things to remember when doing problems based on data interpretation:

1. Take your time and read carefully. Understand what you are being asked to do before you begin figuring.

2. Check the dates and types of information required. Be sure that you are looking in the proper columns, and on the proper lines, for the information you need.

3. Check the units required. Be sure that your answer is in thousands, millions, or whatever the question calls for.

4. In computing averages, be sure that you add the figures you need and no others, and that you divide by the correct number of years or other units.

5. Be careful in computing problems asking for percentages.

a. Remember that to convert a decimal into a percent you must multiply it by 100. For example, 0.04 is 4%.

b. Be sure that you can distinguish between such quantities as 1% (1 percent) and .01% (one one-hundredth of 1 percent), whether in numerals or in words.

c. Remember that if quantity X is greater than quantity Y, and the question asks what percent quantity X is of quantity Y, the answer must be greater than 100 percent.

WHAT DO WE UNDERSTAND BY DATA?

Data refers to facts or numbers, collected for examination, consideration and useful for decision-making. It is in raw form i.e. it is in a scattered form. Information refers to data being arranged and presented in a systematic or an organize form, so that some useful inferences can be drawn from the same. By data we generally mean quantities, figures, statistics, relating to any event.

WHAT DO YOU UNDERSTAND BY DATA INTERPRETATION?

As the name implies, Data Interpretation is extraction of maximum information, as required by us from the given set of data or information. In other words the act of organizing and interpreting data to get meaningful information is known as Data Interpretation. The representation of data can be broadly classified as tables and graph.

TABLES: Any statistical data pertaining to a situation can be represented by tables. Tables are the easiest and most convenient form of data representation if the data is reasonably limited.

(1) Tables present data logically.(2) Tables give a bird’s eye-view of the data in a concise and a compact manner thereby saving time and space.(3) The columns and the rows that constitute any table facilitate data comparison.(4) Tables facilitate also analysis and informed decision-making, a la any other data representation type.

1. In 1997 production is 91% of capacity installed

Therefore=91*400,000/100

=364,000

Hence [3]

2. Inventory for 1994

Production in '94=330,000

Sales=297,000 therefore inventory=33,000

Inventory for 1995

Production in 1995=340,000

Sales in 1995=306,000 therefore inventory=34000

Sales for 1996=360000

Total sales=360000+34000+33000=427000 units

Sales revenue=427000*4.84

1. (135 + 137 + 141 + 144 + 145)/5 = 702/5 = 140.4

2. Average Production= (126 + 130 + 132 + 134 + 136)/5 = 131.5

In 1997 and 1998 the production was 126 and 130 which is less than the average production, hence twice.

3. 1997-1998(137 -135)/135 * 100= 1.48

1998-1999(141-137)/137* 100 = 2.919

1999-2000(144-141)/141 * 100 = 2.217

2000-2001( 145-144)/144 * 100 = 0.694

1999 recorded greatest % increase in production.

4. Production in 2002 will be 136(1.1) = 149.6,but details about requirement is not given. Hence the difference between requirement and production can’t be determined.

5. P = 2R 3P + R = 355P = (2 * 355 ) /5= 142

% increase = (142 – 136)/136 = 4.41
