Edited By Team Careers360 | Updated on Aug 26, 2024 08:38 AM IST | #CAT

The CAT exam for MBA admissions 2025-2027 is scheduled for November 24, 2024. In this 60-day CAT 2024 preparation guide series by Careers360, we’ll discuss strategies for tackling permutation and combination problems on Day 37, helping you prepare effectively and succeed in the CAT entrance test.

This article covers permutation and combination problems, syllogism questions with answers, and tips for understanding comparison in VARC. Permutation and combination problems are often considered challenging, and many aspirants struggle with them. To aid your preparation, we've included permutation and combination examples with answers, as well as previous years' questions (PYQs) for practice.

Part-1: Quantitative Aptitude for CAT 2024

Topic: CAT Number System-4 (Factors and Trailing Zeroes)

Factors:

CAT number system questions based on factors are regularly asked in the CAT exam and other MBA entrance examinations.

Questions about factors are of the form of

  • To find the number of all factors

  • To find the number of even factors

  • To find the number of odd factors

  • To find the number of factors of multiple of some value (Value will be given)

  • To find the number of factors which are perfect squares/perfect cubes etc

  • To find the number of Co-prime factors

  • To find the sum of factors

  • To find products of all factors etc.

  • Number of ways of writing a number N as a product of two numbers?

Important Formula for CAT number system questions

Number of factors:

Do Prime factorization first

N = pa × pb × rc × … where p, q, r are prime numbers; a, b, c are positive integers

The number of factors of N= (a+1)(b+1)(c+1)…

Sum of factors

Do prime factorisation first.

N = pa × qb × rc × … where p, q, r are prime numbers; a, b, c are positive integers

Sum of factors = (pa+1-1/p-1) (qb+1-1/q-1) (rc+1-1/r-1)

Trailing Zeroes and Exponent of a prime number:

Trailing zeroes give the number of zeroes at the end of the number.

For example, 54600 has two trailing zeroes.

In a product, a pair of 2 and 5 forms one trailing zero. This concept is used to find the number of trailing zeroes.

From this topic following types of questions were asked:

  • Find the trailing zeroes in 54! etc
  • Find the trailing zeroes in x3b x5c etc
  • Find the highest power of 7 in 200! etc

Previous Year CAT questions on number system

The two previous year CAT questions as per the number system CAT Syllabus are given below:

Q1. How many factors of 24 × 35 × 104 are perfect squares which are greater than 1? [TITA- CAT Question Paper 2019]

Solution:

N = 24 × 35 × 104 = 24 × 35 × 24 x 54 = 28 × 35 × 54

Perfect square factors will be formed only for even (including 0) powers of prime factors.

Powers of 2 for which perfect square factors will be found for = 0, 2, 4, 6, 8 (5 ways)

Powers of 3 for which perfect square factors will be found for = 0, 2, 4 (3 ways)

Powers of 5 for which perfect square factors will be found for = 0, 2, 4 (3 ways)

Total number of perfect square factors will be = 5 x 3 x 3 = 45

Total number of perfect square factors greater than 1 will be = 45 – 1= 44

So, the answer is 44.

Q2. What is the highest power of 12 that divides 54!

Solution: A

12 = 22 x3, so we need to count the highest power of 2 and highest power of 3 that will divide 54!

The highest power of 2 divides 54! = [54/2] + [54/4] + [54/8] + [ 54/16] + [54/32]

= 27 + 13 + 6 + 3 + 1 = 50, where [x] ? greatest integer function.

Highest powers of 4 that divides 54! = 50/2 = 25

Highest power of 3 that divides 54! = [54/3] + [54/9] + [54/27] = 18 + 6 + 2 = 26, where [x] ? greatest integer function.

So, the highest power of 12 that divides 54! = min (25, 26) = 25.

Prerequisite:

To prepare for the number system for CAT exam according to the number system CAT syllabus, a student must have knowledge of

  • Prime, Composite and Co-primes

Tips On CAT Preparation For Number System (Factors and Trailing Zeroes)

  1. Find the number of 5s to find the trailing zeroes is n! as the number of 2s is always greater than the number of 5s.
    Eg: number of trailing zeros in 100! = [100/5] + [100/25] = 20 + 4 =24 where, [x] is the greatest integer function.
    So, we can write the number of trailing zeroes in n! = [n/5] + [n/25] + [n/125] + ……….
  2. Product of all factors of N = N (no of factors/2)
  3. To find the even factors, divide the given number by 2 and find the number of total factors of the quotient.
  4. Apply the concepts to practice Number System questions.
  5. Practice previous year CAT questions on number system

Part-2: Data Interpretation And Logical Reasoning For CAT 2024

Topic: Data Interpretation (Table)

In previous articles, we have covered DI based on Bar graphs, Pie charts and Line graphs. In this article, we will deal with data represented in the form of a table for the CAT exam. Data interpretation is a must-come topic in the CAT Exam and other management entrance exams.

DI on Table Chart

In this section, we will discuss the basics of a table chart. The boxes of the table consist of different types of information such as the population of a town, marks of a student, expenses of a company, production data of any industry etc. Table Chart questions are extremely important and have a good weightage as well. Many students sometimes find it difficult to solve these types of questions. Therefore, its recommended for students to practice these questions rigorously.

Questions On the Line Graph From CAT Previous Year Papers

Answer the questions on the basis of the information given below. A study was conducted to ascertain the relative importance that employees in five different countries being assigned to five different traits in their Chief Executive Officers. The traits were compassion (C), decisiveness (D), negotiation skills (N), public visibility (P), and vision (V). The level of dissimilarity between two countries is the maximum difference in the ranks allotted by the two countries to any of the five traits. The following table indicates the rank order of the five traits for each country. [ CAT Question Paper 2015]

1694515087946

Q1. Which of the following pairs of countries are most dissimilar?

  1. China and Japan

  1. India and China

  1. Malaysia and Japan

  1. Thailand and Japan

Ans: (4)

Difference in ranks skills-wise is shown as below:


C

N

D

V

P

China and Japan

3-2 =1

2-1 =1

4-1 =3

5-4 =1

5-3= 2

India and China

2-1= 1

3-1 =2

5-4 = 1

5-4 = 1

3-2 =1

Malaysia and Japan

4-3 =1

5-2 =3

2-1= 1

4-1 = 3

5- 3 =2

Thailand and Japan

3-2 =1

3-2 =1

5-1 =4

4-1 =3

5-4=1

Thailand and Japan should be the answer since these countries show the maximum difference in ranks (i.e., 4) on the basis of decisiveness.

No other countries show a difference of 4.

Q2. Which of the following countries is least dissimilar to India?

  1. China
  2. Japan
  3. Malaysia
  4. Thailand

Ans: (1)

Difference between the ranks on the basis of given traits of other countries with India is calculated.

Traits

China

Japan

Malaysia

Thailand

C

2-1=1

5-1=4

4-1=3

2-1=1

P

3-2=1



4-2=2

N

3-1=2



3-3=0

V

5-4=1



4-2=2

D

5-4=1



5-5=0


India and China show a maximum difference of 2 for 1 time.

India and Japan show a difference of greater than 2 (Compassion), so it cannot be least dissimilar and we need not to calculate differences for other traits.

Similar is the case with Malaysia.

With Thailand, the difference of 2 appeared twice. Therefore it can not be least dissimilar. The answer is China.

Q3. Which amongst the following countries is most dissimilar to India?

  1. China
  2. Japan
  3. Malaysia
  4. Thailand

Solution: (2)

since China is the least dissimilar, as discussed in the previous question. So, China cannot be the answer, and we will not find the differences for China in this case.

Traits

Japan

Malaysia

Thailand

C

5-1=4

4-1=3

2-1=1

P

5-2 =3

3-2=1

4-2=2

N

3-2=1

5-3=2

3-3=0

V

4-4=0

4-1=3

4-2=2

D

3-1=2

5-2=3

5-5=0

Clearly, Japan shows the maximum difference in ranks, So Japan is most dissimilar in ranks with India

Part-3: VARC for CAT 2024

Topic: Conjunction and Interjection and its uses:

Conjunctions are used to connect more than two words or phrases. It defines the connection between the joined sentences.

Examples:

He likes to eat both Noodles and Pizza.

The tulips and orchids are flowers.

Until next month, I can’t afford to travel.

Conjunctions are useful as well as convenient. Conjunctions are extremely common.

There are three types of English conjunctions:

Coordinating: for, not, yet, so etc

Subordinating: Although, though, while, if, until etc.

Correlative: Neither/ Nor, Whether/ Or, Either/ Or etc.

Interjections are used to express emotions in a sentence. Also, interjections are grammatically independent of the words around them.

Examples:

Greeting: Hey! After such a long time, I am seeing you.

Joy: Oh my gosh! What is happening there?

Surprise: Ah! Finally you clear your CAT Exam!

Approval: Yes! you are hired!

Attention: Listen, you are fired.

Sorrow: Oh dear, I really wanted to marry you.

Questions On Conjunction and Interjection from CAT Previous Year Papers/ CAT practice questions on conjunctions

Direction: Choose the part which requires correction. [Based on Previous Years Questions]

Q.1 As soon as (1) / he got the (2) / courier, at once (3) / he started. (4) / No Error (5)

  1. (1)

  1. (2)

  1. (3)

  1. (4)

Ans: C

The conjunction 'as soon as is used to show two simultaneous actions. So, in the third part, the use of ‘at once’ is incorrect

Q2. I will either (1) / go for an interview (2) / else play (3) / Cricket. (4) / No Error (5)

  1. 1

  1. 2

  1. 3

  1. 4

  1. 5

Ans: C

With “Either’, ‘Or’ comes.

So, (3) contains error. ‘else’ should be replace by ‘or’.

Q3. Be kind (1)/ not only in words (2) / and also (3) / in behavior. (4) / No Error (5)

  1. 1

  1. 2

  1. 3

  1. 4

  1. 5

Ans: C

The correct conjunction to be used is ‘but’ in place of ‘and’.

Prerequisite:

  • Knowledge of sentence formation
  • Basic Knowledge of Sentence Formation
  • Use of Nouns, Pronouns and Verbs.

CAT Preparation Tips for Verbal Ability (Conjunction and Interjection)

Use of the comma when a coordinating conjunction is joining two independent clauses.

When a conjunction joins two words in a sentence, then the sentence cannot be separated in two independent sentences.

Learn all the conjunctions and their uses separately with the help of examples.

Hello aspirant,

The CAT authorities may initiate a verification process to ensure the accuracy of your caste information. This could involve contacting the issuing authority of your EBC certificate or requesting additional documents.
If the verification process confirms your EBC status, your category might be changed to EBC. This could potentially affect your eligibility for certain seats or scholarships.
If your EBC certificate is not accepted as proof of OBC status, you might be ineligible for OBC reservations. However, you would still be eligible to appear for the CAT exam as a General category candidate.

It's crucial to:

  • Monitor your application status: Keep an eye out for any communications from the CAT authorities regarding your application and caste verification.
  • Provide necessary documents: If requested, promptly submit any additional documents that might be required to verify your caste status.
  • Contact CAT authorities: If you have any concerns or questions, don't hesitate to reach out to the CAT helpline or support team.

Remember: The final decision regarding your eligibility for OBC reservation will depend on the specific policies and procedures of the CAT authorities.

I hope this information helps you.
