The CAT 2024 exam for MBA admissions will be conducted in November 2024, and we've prepared a 60-day study plan to help you qualify for the exam. The Common Admission Test (CAT) is difficult, and being acquainted with its ideas is critical to passing it. In this article, we will go over three important topics: divisibility laws, line graphs, and verbs. These topics are typically included in the CAT examination, so studying them will help you prepare. We will also go over some previous year's questions to help you prepare.

How To Prepare CAT Quantitative Aptitude Strategy | DI, VA and LR - Day 3

Divisibility:

To solve the Divisibility and remainder CAT questions, you must know the divisibility rules for different prime and composite numbers.

Here are some rules:

Divisor

Divisibility condition

Examples

2

The last digit is even (0, 2, 4, 6, or 8).

1,564: 4 is even.

3 or 9

Sum the digits. If the result is divisible by 3 (9), then the original number is divisible by 3 (9).

405 → 4 + 0 + 5 = 9 and 699 → 6 + 9 + 9 = 24 which both are clearly divisible by 3.

405 is divisible by 9 also but 699 is not.

4

Examine the last two digits.

46532: 32 is divisible by 4.

5

The last digit is 0 or 5.

875: the last digit is 5.

6

It is divisible by 2 and by 3.

1,368: 1 + 3 + 6 + 8 = 18, so it is divisible by 3 and the last digit is even, hence the number is divisible by 6.

8

Examine the last three digits.

84176: Examine divisibility of just 176: 22 × 8 = 176

11

Form the alternating sum of the digits.

918,082: 9 − 1 + 8 − 0 + 8 − 2 = 22.

Eg: (i) 369 is divisible by 3 since some of the digits are divisible by 3.

(ii) 678 is divisible by 6 since it is divisible by both 2 and 3.

How will you check whether a number is divisible by 18, 24, or 72 (composite numbers)?

Do the Co-prime factors of the divisor. And the given number must be divisible by co-prime factors.

18 = 2 and 9 (For 18, the number should be divisible by 2 and 9 both)

24 = 3 and 8 (For 24, the number should be divisible by 3 and 8 both)

72 = 8 and 9 (For 72, the number should be divisible by 8 and 9 both)

Remainders:

As we all know

Dividend = Divisor x Quotient + Remainders

Questions based on remainders are being asked in the CAT exam. You must prepare this topic separately as there are many rules to find the remainder. Some of them are listed below:

  • Binomial Theorem

  • Method of Cancellation

  • Fermat Little Theorem

  • Chinese Remainder Theorem

  • Wilson Theorem

CAT Quant Questions With Solutions (Number System) From CAT Previous Year Papers/ CAT questions on Divisibility Rules:

Question 1. The remainder when 292929 is divided by 9 is? [IPMAT 2019]

  1. 3

  2. 4

  3. 2

  4. 1

Solution: (A)

If we divide 29 by 9, the remainder is 2.

So, we now will divide 22929 i.e. 2841 to get the remainder.

2841 can be written as 2(3x280+1) = (8280)x2

When we divide 8 by 9, the remainder is -1.

When divided by 9, will give as the remainder of ((-1)280)x2 = 2

1694779517972

Question 2: If then x divided by 70 leaves a remainder of: [CATQuestion Paper 2005]

  1. 0

  2. 1

  3. 69

  4. 35

CAT remainders questions with solution

Solution: (A)

Rem (163/70) = Rem (4096/70) = 36

Rem (173/70) = Rem (4913/70) = 13

Rem (183/70) = Rem (5832/70) = 22

Rem (193/70) = Rem (6859/70) = 69

Net Remainder = 36 + 13 + 22 + 69 = 140.

When 140 is divided by 70, the remainder is 0.

Question 3. How many of the integers 1, 2, … , 120, are divisible by none of 2, 5 and 7? [CAT Question Paper 2020]

  1. 41

  2. 42

  3. 40

  4. 43

Ans: (A)

Number of multiples of 2= 2, 4, 6, 8, ………, 120 (Total of 60 numbers)

Number of multiples of 5 = 5, 10, 15, 20……….., 120 (Total of 24 numbers)

Number of multiples of 7 = 7, 14, 21, …….., 119 (Total of 17 numbers)

Number of multiples of 2 and 5 =10, 20, …., 120 (Total of 12 numbers)

Number of multiples of 2 and 7 = 14, 28, ………, 112 (Total of 8 numbers)

Number of multiples of 7 and 5 = 35, 70, 105 (Total of 3 numbers)

Number of multiples of 2, 5 and 7 = 70 (Total of 1 number)

Total Numbers divisible by any of 2, 5 or 7 =(1) + (2) + (3) – (4) –(5) –(6) +(7)= 60+ 24+ 17 – 12 - 8 – 3 + 1= 79

Therefore, Numbers divisible by none of 2, 5 and 7 = 120 – 79 = 41.

Prerequisite:

The CAT exam requires students to have knowledge of the basic elements that are given below.

  • Prime numbers, composites, and Co-Primes

  • Even and Odd numbers

  • Digit Sum

  • Binomial Expansion

  • Multiples and Factors

  • Expansion of (a+b)n and (a-b)n where n is any positive integer.

Tips On CAT Preparation For Number System:

  1. Remainder is equal to sum of individual remainders.

Eg: If (72 + 37 + 89) is divided by 7

Remainder = Rem (72/7) + Rem (37/7) + Rem (89/7) = 2 + 2+ 5 =9

Since sum is greater than 7, again divide 9 by 7 to find the remainder i.e. 2.

  1. A number is divisible by a composite number if only if it is divisible by its co-prime factors.

  2. Learn Divisibility rules and apply them to different questions for better CAT Quant preparation.

Part-2: Logical Reasoning And Data Interpretation

Topic: Data Interpretation (Line Graph)

As discussed in the previous article, Data interpretation is the most important topic for CAT Exam and other management entrance Exams. We have discussed the strategies to prepare Bar graphs and Pie charts previously.

In this section, we will learn about line graphs. Similar skills like Skills of observation, doing calculations quickly, analyzing things, and comparison of values will be required while solving the problems of DI based on Line graphs.

What is a Line Graph?

In this section, we will focus on the most basic aspects of a line graph and how to solve line graph questions.

1694779518305

  • On the y-axis, a dependent variable is taken while on the x-axis, an independent variable is taken.

  • Dots represent the values of x and y variables at that point.

  • Line gives a visual representation of the data and its variation.

  • Vertical Label: Name of Dependent Variable

  • Horizontal Label: Name of Independent Variable

  • Slope of the line gives the variation of data i.e. if slope is positive then growth is positive and if slope is negative then growth is negative

Part-3: VARCTopic: Verb and its Uses:

Verbs are part of “parts of speech,” which express an action or the state of being.

Examples:

He missed the train. (Here, "missed" describes the action.)

The dog is sleeping. (In this, "sleeping" expresses the state.)

Further, verbs can be classified as

  • Transitive,

  • Intransitive

  • Helping verbs.

In the above example 1, "missed" is a transitive word.

In example 2, ‘sleep’ is an intransitive verb.

In example 2, "is" is a helping verb, while "sleeping" is the main (action) verb.

Frequently Asked Questions (FAQs)

1. What is Line Graph?

A line graph is an easy method to demonstrate how something evolves over time or how two items are connected. To show these changes, it draws a line connecting points on the graph.

2. What is a Binomial Theorem?

The Binomial Theorem simplifies the expansion of formulas like (x+y)^n, particularly when n is large. Normally, expanding these equations would take a long time, but the Binomial Theorem gives a formula that makes the process faster and simpler. This involves learning how to compute binomial coefficients, grasping the elements of the theorem, and applying it to various applications. It's a handy tool for managing lengthy, complex expansions.

3. What does the X and Y axis represent on a Line Graph?
  • The X-axis (bottom line) usually depicts time or categories such as days, months, or types of item.

  • Y-axis (side line): Displays numbers such as sums, temperatures, or scores.

4. What is Verb and its uses?

A verb is a term that expresses what someone or something is doing or indicates a state of being. Verbs may describe activities, such as running or eating, or they can refer to additional information, such as stating that someone is satisfied. Some verbs, such as has and will, also aid in the expression of time. In layman's words, verbs are vital because they inform us what is occurring in the sentence, whether it's an action, an emotion, or a situation.

5. What is Total revenue?

Total revenue is the entire amount of money a firm earns by selling its goods or services. It is determined by multiplying the price of each item by the quantity sold. It refers to the company's sales profits before removing any expenses.

They started with three items on the menu. One was the French Toast which could be prepared in 3 minutes. The second was the Egg Tortillas which took 15 minutes to prepare. Any one of Moloy and Niloy could prepare any one of them at a time. The third was the Egg Bhurji with French Fries. This however was prepared on an automated fryer which could prepare 3 servings at a time and took 5 minutes irrespective of the number of servings equal to or below 3. The fryer did not need anyone to attend to it, and the time to put in the raw ingredients could be neglected. So one could tend to the preparation of other items while the Egg Bhurji with French Fries were being prepared. 

They wanted to serve the orders as early as possible after the order was given. The individual items in any order were served as and when all the items were ready, and the order was then considered closed. None of the items on the menu were prepared in advance in anticipation of future orders. 

On the first day, 3 groups of customers came in and ordered at 6.00 pm, 6.10 pm, and 6.13 pm. The first order was for a plate of Egg Tortillas, two plates of French Toast, and three plates of Egg Bhurji with French Fries. The second order was for a plate of French Toast and two plates of Egg Bhurji with French Fries. The third order was for a plate of Egg Tortilla and a plate of Egg Bhurji with French Fries. 

On the backdrop of the above information answer the questions given :
