CAT 2019 - Syllabus, Exam Pattern, Learn Concepts, Selection Criteria
The CAT exam consists of 3 sections - Verbal Ability and Reading Comprehension, Data Interpretation & Logical Reasoning, Quantitative Ability.
Quantitative Ability and Data Interpretation & Logical Reasoning in CAT exam syllabus are focused to judge the person's ability to crunch numbers, concepts and applying the same within the limited time span whereas Verbal Ability and reading comprehension are to know the person's command over the language.
A total of 100 questions are to be solved in 180 minutes. Each correct response carries 3 marks, while each incorrect response carries -1 marks. Non-MCQ questions will not be negatively marked.
- VA-RC - This section consists of 20-25 Reading Comprehension questions and the rest consist of Verbal Ability questions.
- DI-LR - This section consists of 8 sets of 4 questions each. Anywhere between 2-4 sets of Data Interpretation questions can be expected in CAT exam 2019.
- QA - This section consists of 34 questions from various topics. Based on historic trends, most questions for CAT 2019 can be expected to be from Geometry, Arithmetic, and Algebra (in descending order).

1. Cyclicity and Unit Digit of a Number
Cyclicity is a basic but a very important concept in CAT exam and is used to find unit digit of a particular number. No matter what the number is or what power the number has, you can use the concept of cyclity to find the unit digit of that number in seconds.
So, starting with the concept, every no. say "x^n" repeats its unit digit in a cycle of 4 (power).
Number | x^1 | x^2 | x^3 | x^4 | |
1 | 1 | 1 | 3 | 4 | |
2 | 2 | 4 | 8 | 6 | |
3 | 3 | 9 | 7 | 1 | |
4 | 4 | 6 | 4 | 6 | |
5 | 5 | 5 | 5 | 5 | |
6 | 6 | 6 | 6 | 6 | |
7 | 7 | 9 | 3 | 1 | |
8 | 8 | 4 | 2 | 6 | |
9 | 9 | 1 | 9 | 1 |
For instance, you have to find the unit digit of (348)^21
The unit digit of (348)^21 will solely depend upon 8 and not on any other digit. Now divide the power 21 in the form of (4n + a). Thereby we can write 21 as 4(5) + 1. So, as fore-stated the unit digit repeats itself in a cycle of 4, we can say that the unit of (348)^21 = (348)^1.
Therefore, unit digit of (348)^21 = 8^1 => 8.
2. Number of squares and rectangles in a chess board
In a n*n chessboard,
The total no. of squares = 1^2 +2^2+3^2+…..+n^2
= n*(n+1)(2n+1)/6 (summation formula)
and the total no. of rectangles are given by: 1^3 +2^3+3^3+…..+n^3
=[{n^2}*{(n+1)^2}/4
So, for instance in a 8*8 chessbosard,
no. of squares are: 8*(8+1)(2*8+1)/6
i.e. 8*9*17/6
=1,224/6 => 204
and no. of rectangles are given by: [{8^2}*{(8+1)^2}/4
i.e. 64*9^2*/4
=5,184/4 => 1296 (this includes the no. of squares as well)
No. of rectangles, which are not squares are: 1296 - 204 => 1092 learn more
