Edited By Team Careers360 | Updated on Sep 18, 2024 05:05 PM IST | #CAT

Practicing Number Systems is essential for every MBA aspirant. It’s a broad topic that requires a thorough review alongside other quantitative subjects. In the CAT exam, Number System questions typically make up about 5% of the Quant section, with 1-2 questions appearing each year based on past papers. This article is part of a 60-day preparation plan for CAT. Candidates can use this and other articles in the series to strengthen their understanding of Number System questions for the CAT exam.

What are Numbers?

A number is referred to as a mathematical value which represents a certain quantity. In the international number system, the place values are called “Ones(1), tens(10), hundreds(100), thousands(1000), ten thousands(10,000), hundred thousands(1,00,000), millions(10,00,000), ten millions(107), hundred millions(108), billions(109) and so on.

The classification of the Number system is as follows:

  • Real numbers: All numbers in the number line including positive, negative and zero.

  • Imaginary numbers: Numbers when squared give a negative number.

  • Rational Numbers : Numbers that can be expressed as p/q form, q ≠ 0

  • Irrational numbers: Numbers that cannot be expressed as p/q form

  • Integers: Numbers that can be positive, negative and zero excluding fractions.

  • Whole numbers: Positive numbers including zero

  • Natural numbers: Positive numbers excluding zero, start from 1.

Previous Year CAT Questions on the Number System

Question 1: Let m and n be natural numbers such that n is even and 0.2 < m/20, n/m, n/11< 0.5.
Then m – 2n equals:

[CAT Question Paper 2020]

  1. 4

  2. 2

  3. 1 - Correct answer

  4. 3

Great Lakes - PGPM & PGDM 2025

Admissions Open | Globally Recognized by AACSB (US) & AMBA (UK) | 17.3 LPA Avg. CTC for PGPM 2024 | Application Deadline: 1st Dec 2024

Nirma University MBA Admission 2025

Highest CTC 70 LPA | Avg CTC 11.22 LPA | Ranked #55 by NIRF

Solution:

0.2 < m/20, n/m, n/11 < 0.5
⇒ 1/5 < m/20, n/m, n/11 < ½

Taking one at a time, we get
1/5 < m/20 and m/20 < ½
So, m > 4 and m < 10
Therefore, possible values of m = 5, 6, 7, 8, 9

Now, 1/5 < n/11 and n/11 < ½ and n is even.

So, n > 11/5 and n < 11/2

Therefore, a possible value of n is 4 (since 4 is the only even natural number between 11/5 and 11/2)

Since 0.2 < n/m < 0.5

⇒ 20 > m > 8 [Putting the value of n = 4]

So, the only possible value of m is 9.

Now, m – 2n = 9 – 2 × 4 = 1

Hence, the correct answer is 1.

Question 2: Convert the number 1982 from base 10 to base 12. The result is?

(CAT Question Paper 2000)

  1. 1182

  2. 1912

  3. 1192 - Correct answer

  4. 1292

Answer:

For that, divide 1974 by 12 as shown:

Write the remainder from bottom to top.

So, in base 12, 1982 is 1192.

Hence, the correct answer is 1192.

Question 3: If n is an integer and n(n + 1)(n + 2) is divisible by 8, which of the following is necessarily true?

  1. n is even - Correct answer

  2. n is odd

  3. n is divisible by 8

  4. n is not divisible by 8

Answer:

For n(n+1)(n+2) to be divisible by 8, at least one of the factors n, (n + 1), (n + 2) must be divisible by 2, and at least one must be divisible by 4.

The product of three consecutive integers always contains at least one multiple of 2 and one multiple of 4, ensuring that their product is divisible by 8.

This happens when n is even.

Hence, the correct answer is “n is even”.

Question 4: If the sum of the squares of three consecutive positive integers is 2030, then the middle integer is:

  1. 25

  2. 26 - Correct answer

  3. 27

  4. 28

Answer:

Let the three consecutive integers be n, n + 1, and n - 1.

According to the question,

n2 + (n + 1)2 + (n - 1)2 = 2030

⇒ n2 + n2 + 2n + 1 + n2 - 2n + 1 = 2030

⇒ 3n2 = 2030 - 2

⇒ n2 = 676

⇒ n = 26, which is the middle number.

Hence, the correct answer is 26.

Prerequisite to CAT preparation for number systems

Here are some must-learn topics for students to do thoroughly while preparing for CAT:

  • Tables up to 30

  • Squares up to 30

  • Cubes up to 20

  • Prime numbers until 100.

  • Knowledge of Fractions

How to prepare for Number Systems (Basics)?

  1. Learn the Classification of Numbers (Natural, Whole, Integers, Prime, Composite, Co-prime, etc.). NCERT books (9-10th standard) are the best guides for this.

  2. Apply the concepts to number system questions.

  3. Learn Base systems and conversions from numbers in one base system to another. For example, fractions to decimals questions, how to remove decimal points in fractions, how to convert numbers to fractions, and number system questions, and answers.

  4. Practice the previous year's CAT questions on the number system.

Easy tips and formulae for number systems:

  1. Following are some useful tips and CAT formulae on the Number system that can help in your preparation:

  • The sum of a two-digit number and a number formed by reversing its digits is divisible by 11. E.g., 24 + 42 = 66, this is divisible by 11.

  • At the same time, the difference between those numbers will be divisible by 9. e.g., 42 – 24 = 18, this is divisible by 9.
  • ∑n = n(n + 1)/2, ∑n is the sum of the first n natural numbers.

  • ∑n2 = n(n + 1)(2n + 1)/6, ∑n2 is the sum of the Perfect squares of the first n natural numbers.

  • ∑n3 = n2(n + 1)2/4 = (∑n)2, ∑n3 is the sum of the perfect cubes of the first n natural numbers.

  1. Learn Recurring and Non-recurring decimal numbers and their conversion to fractions.
    Number of the form of 0.a = a/9
    Eg. 0.77777…. = 7/9

  • Number in the form of 0.ab = ab/99
    Number in the form of 0.abc = abc/99
    Eg. 0.73737373….. = 73/99
    0.343343343…. = 343/999

  • Number of the form of 0.0a = a/90
    Eg. 0.07777….. = 7/90

  • Number of the form of 3.ab = (3ab – 3)/99
    Number of the form of 30.ab = (3ab – 30)/99

Data Interpretation(DI) for CAT 2024

Data interpretation is a must-know topic for the CAT Exam and other MBA entrance exams. Data interpretation tests your analytical and observational skills to deduce useful information and apply it to solve the given questions. DI for CAT can be studied in parts such as Bar graphs, Pie charts, Line graphs, Tables, Caselet, Spider charts, and Miscellaneous.

What is a Bar graph?

The bar graph definition says that a graph where data is represented with rectangular bars where one parameter is given on the x-axis and the other parameter is given on the y-axis.

These bars can be drawn horizontally or vertically. Every bar represents a different category and the length of the bar is its value.

We also have to study “bar graph maker”, “bar graph examples”, “difference between histogram and bar graph” and practice bar graph questions to delve deeper into this topic.

Examples of Bar graphs with questions

Question. Examine the graph below carefully and answer the following questions. The graph depicts the results of a school’s students.

1693836873789

  1. Which year has the smallest difference between the number of kids who passed and those who failed?

  2. In the last five years, what was the average number of kids who failed in school?

  3. How many times have the same number of kids failed?

Solution:

(A) The number of pupils who passed versus those who failed for the respective years is given below:

1991-1992 = 150 – 100 = 50

1992-1993 = 200 – 100 = 100

1993-1994 = 300 – 50 = 250

1994-1995 = 250 – 100 = 150

The difference in 1991-1992 is minimal.

Hence, the correct answer is 1991-1992.

(B) From the bar graph, we can observe that.

The total number of students failed = 100 + 100 + 50 + 100 + 100 = 450

So, Average = 450/5 = 90

Hence, the correct answer is 90.

(C) According to visual observation, the number of failed students in 1991-1992, 1992-1993, 1994-1995, and 1995-1996 is the same.

Hence, the correct answer is four.

DI based on the Bar Graph for the CAT exam.

Bar graphs are the pictorial representation of data (generally grouped), in the form of vertical or horizontal rectangular bars, where the length of bars is proportional to the measure of data. Every bar represents a different category and the length of the bar is its value. They are also known as bar charts.

As per previous year's question papers for the CAT, about 3 or 4 questions are expected related to Bar Graph questions for the CAT which come in exams.

Questions On Bar Graph From CAT Previous Year Papers

Revenue Shares of Tech Companies

Question 1: In 2001, the company that grew the quickest grew by 100%. What was the growth rate of the company that had the least growth rate?

  1. 50%

  2. 25%

  3. 20%

  4. 33% - Correct answer

Solution for Question 1:

Let the total revenues of the entire industry be 100x in 2000 and 100y in 2001.

Company

Share in 2000 (approx.)

Share in 2001 (approx.)

Share in 2001: Share in 2000

FINY

22.9x

21.1y

21.1y : 22.9x

PRIWO

17.1x

19.3y

19.3y : 17.1x

SCT

25.7x

21.1y

21.1y : 25.7x

GOCN

14.3x

14y

14y : 14.3x

BIM

8.6x

10.5y

10.5y : 8.6x

CENTURE

11.4x

14y

14y : 11.4x

The company that grew the quickest would be the one that had the maximum ratio of 2001 revenue share to 2000 revenue share. Only the shares matter, X's and Y's do not matter.

Clearly, CENTURE saw the highest ratio and hence the highest growth, which is equal to 100%, and for that share in 2001: share in 2000 = 2 : 1 (for CENTURE).

So, 14y/ 11.4x = 2/1

⇒ y/x = 11.4/7

The company that saw the least ratio, and hence the least growth rate, is SCT.

Share in 2001: Share in 2000 = 21.1y/25.7x = (21.1/25.7) × (11.4/7) = 1.33

So, the percentage change is 33%.

Question 2: In 2002, the growth rate of the overall sector was 39%. What was the growth rate seen by SCT?

  1. 50% - Correct answer

  1. 75%

  2. 30%

  3. 40%

Solution for Question 2:

Let Revenue in 2001 be 100.

Then Revenue in 2002 was 139.

Share of SCT in 2001 = 21.1% of 100 = 21 (Approx)

Share of SCT in 2002 = 22.8% of 139 = 32 (Approx)

Therefore, Percentage Change = 11 × 100/21 = 52% ≈ 50% (Approx)

Question 3: Total revenue in 2006 was 21.2 billion and total revenue in 2005 was

18.1 billion. What was the growth rate seen in Centure?

  1. 11%

  2. 35%

  3. 20% - Correct answer

  4. 27%

Solution for question 3:

Growth rate = (8.5% of 21.2 – 8.3% of 18.1) × 100/18.1 = 20% (approx.)

Hence, the correct answer is Option C.

Prerequisite:

Here are some must-learn topics for students to do thoroughly while preparing for CAT:

  • Tables up to 30

  • Squares up to 30

  • Cubes up to 20

  • Basics of Percentage

  • Must know to find averages

In the Verbal Ability and Reading Comprehension section, 24 questions are included among which 19 questions are Non-MCQ questions. The Reading Comprehension questions are the majority ( 80%). CAT English practice questions are important as sometimes students are very overconfident that they can solve the questions but they can’t, so thorough practice is a must.

What are Nouns?

Nouns are a part of speech comprising words used to name people, places, animals, objects, and ideas. Nouns can act as the subject, an indirect object, a direct object, a subject complement, and an object complement.

Some of the types of nouns are:

  • Proper nouns: Names of specific persons, places, or things

  • Common nouns: Names of general items rather than specific names.

  • Countable nouns: Nouns that can be counted.

  • Uncountable nouns: Nouns that can not be counted.

  • Abstract nouns: Nouns that can not be perceived by 5 human senses.

  • Concentre nouns: Nouns that can be perceived by 5 human senses.

  • Compound nouns: Made up of two or more small nouns.

  • Collective nouns: Nouns referring to groups rather than individuals.

To understand better, we can make a types of nouns chart with types of nouns with examples.

We can also practice on the “countable and uncountable nouns worksheet”, “common and proper nouns worksheet with answers”, and “singular and plural nouns worksheet”

The student cannot join the postgraduate MA program directly in the second year of the MA after completing the MBA.


Universities generally expect students to begin the first year of a masters' program even though they had qualifications at the level of a bachelor's degree. The university's curriculum along with the courses are planned to give an in-depth knowledge of the subjects.


But you could opt for:


Postgraduate Studies:


Research Career: In case research interests you, then you can pursue a Ph.D. in your specific interest.

Specialized Master's Programs: Find any specific master's course that supports the career goal.

Professional Certifications:


Make a professional certification in CFA, CA, or FRM to enhance the professional skills and better opportunities in the career field.

Job Entry via MBA

After gaining an MBA from a renowned institution, it's possible to get entry into the corporate world where the diversity in the career field is assured.

In the end, it would depend on what you would like and what you are particularly interested in. It will be better if you take a suggestion from your academic advisor or career counselor.

Hello Pratik,

If your family income exceeds 8 LPA, it will affect your eligibility for the NC-OBC category under the CAT reservation rules. The NC-OBC category requires that the family income should be below 8 LPA to qualify. If you anticipate that your income will exceed this threshold, you should update your status and notify the CAT authorities .

Here's what you can do:

  1. Email the CAT authorities : Inform them about the potential change in your income status and request to be considered under the General category, if applicable. You should do this before the examination or any further processing, as your eligibility for the OBC category depends on the income criteria.

  2. Documents and Proof : Make sure you have a valid OBC certificate and any relevant documentation regarding your family income, in case they require verification. Also, be aware that if your income exceeds 8 LPA, you might need to apply under the General category, as the OBC-NC reservation is no longer applicable.

  3. General Category Consideration : If your application is accepted as General, you will be evaluated based on the General category criteria, including cutoffs and ranking.

To summarize, notifying the CAT authorities is the correct approach to avoid discrepancies later, and if your income is above the threshold, you will be treated as a General candidate for the admissions process.

Hello,

Yes, you can also join IIMs two years after graduation, depending upon the justification in interviews and your performance in entrance exams. If you are not sure about CAT, try those other management exams less hard:

Common Management Admission Test: Easier than CAT; 4-5 months of continuous preparation will suffice.

MAT : Much easier and takes place thrice a year.

SNAP (Symbiosis National Aptitude Test): A bit easier than CAT, apt for Symbiosis Institutes.

Xavier Aptitude Test or XAT : Hence, easier than CAT but the unique decision-making section.

Use exams like CMAT and MAT as a challenge to be competitively prepared. This can be given about 4-5 months, along with a few rounds of mock tests and smart studying.
