Unlocking CAT Exam Essentials: Exploring Unit Digits, Pie Charts, and Pronouns - Day 2
Edited By Team Careers360 | Updated on Sep 19, 2024 02:25 PM IST | #CAT
In our previous article, we covered the CAT Preparation Strategy for Quantitative Ability on Day 1, focusing on the number system and its components, such as classification, converting decimals to fractions, and base systems, along with relevant CAT quant questions.
In this article, we will study deep into the unit digit and the last two digits of a number as outlined in the CAT Quant syllabus for 2024. We'll also review previous year's CAT questions related to the number system. Typically, there are about 3-4 questions on this topic in the exam, based on past CAT quant papers.

For instance, given the number 234432, how would you determine the unit digit and the last two digits of the number?
Part 1: Quantitative Aptitude For CAT 2024
Topic: What is “Cyclicity”?
Cyclicity is used to determine the unit digit. Cyclicity is the power of a number after a multiple in which a unit digit is repeated.
For example, 21 = 2; 22 = 4; 23 = 8; 24 = 16; 2 5= 32 and so on.
As it is shown in the above example, after every fourth power of 2, the unit digit is repeated. So, 4 is cyclicity of 2.
So, you have to learn the cyclicity of every digit.
Digit | Cyclicity (Power Cycle) | Digit | Cyclicity (Power Cycle) |
0 | 1 (Gives always 0 at unit place) | 5 | 1 (Gives always 5 at unit place) |
1 | 1 (Gives always 1 at unit place) | 6 | 1 (Gives always 6 at unit place) |
2 | 4 (2, 4, 6, 8) | 7 | 4 (7, 9, 3, 1) |
3 | 4 (3, 9, 7, 1) | 8 | 4 (8, 4, 2, 6) |
4 | 2 (4, 6) | 9 | 2 (9, 1) |
CAT quant questions based on the last two digits of a number are asked frequently in the CAT Exam.
Eg: Find the last two digits of 3737.
It is practically not so easy to solve this power. So, you need to learn the tricks to find the last two digits without actually solving this problem. Some of the tricks will be discussed later in this article, like dividing a number by 100 so that the remainder is the last two digits.
CAT Quant Questions From CAT Previous Year Papers
Question 1: The product of the last two digits of (1! + 2! + 3!….. 50!) is?
3
4
5
6
Ans: (A)
Divide the given number by 100 to find the last two digits.
Number 10! And greater than 10! are divisible by 100.
So, find (1! + 2! + 3!….. +9!) and divide the result by 100 to get the remainder and hence the last two digits of the number.
So, 1! + 2! + 3!….. +9! = 1 + 2 + 6 + 24 + 120 + 720 + 5040 + 40230 + 362880
So, the sum of the remainder is (1+ 2 + 6 + 24 + 20 + 20 + 40 + 30 + 80). On dividing this result by 100, we get 13 as the remainder.
Product of digits of 13 = 1 × 3 = 3.
Question 2: What are the last two digits of 72008? [CAT Question Paper 2008]

(1,3,7,9)20k = 01 (Last two digits) where k is a positive integer.
So, 72008 = 72000 x 74 x 74 = 01 x 01 x 01 (Taken last two digits only) = 01
So, the answer is 01.
Prerequisite:

The last two digits of x2, (50+ x)2, (50- x)2, (100+ x)2, (100- x)2 are the same.
Eg: 022 = 04
522 = 04
482 = 04
1022 = 04
982 = 04Odd20k = 01(last two digits) except for 5. Where k is a positive integer.
Eg. 2342 = 01(a5)even = 25 (last two digits)
(a5)odd = 75 (last two digits); where can be any digit.
Eg: 13572 = 25, 13523 = 75Even20k= 76(last two digits) where k is a positive integer.

Part 2: Data Interpretation And Logical Reasoning For CAT 2024
Topic: Data Interpretation (Pie Graphs)
As discussed in the previous article, Data interpretation is the most important topic for the CAT exam and other management entrance Exams.
Skills of observation, doing calculations quickly, analyzing things, and comparison of values will help you in solving questions based on Data interpretation (Pie Charts).
In this topic, we are going to discuss strategies to prepare Data Interpretation based on Pie Charts. We will discuss some Pie chart questions on CAT below as well.
What is a Pie Chart (Pie chart basic concept for CAT Exam)?
Sample pie charts of distribution of 6 parameters.
In the pie chart, data is distributed in a circle, which forms 360 degrees at its centre and comprises 100% of its area. Students must know how to derive the relation between angle and Percentage to calculate the parameter’s value.
Pie chart questions and concepts for CAT preparation from CAT Previous Year Papers:
Direction: The break-up of the students in a university by subject major is given in the polar pie chart. The bar chart shows the number of students who major in physics by geographic location. [XAT 2019, based on CAT PYQ]
Question 1. How many students major in chemistry?
200
175
170
190
180
Solution: (B)
Students major in physics = 18 + 36 + 80 + 40 + 23 + 28 = 225 which is 18% of total students.
So, 18% = 225
Major in Chemistry
14% = (225/18) x 14 = 175
Question 2. If the proportion of physics majors who are from Delhi is the same as the proportion of engineering majors who are from Delhi, how many engineering majors are from Delhi?
22
26
18
20
24
Solution: (D)
Students major in physics = 18 + 36 + 80 + 40 + 23 + 28 = 225 which is 18% of total students.
So, 18% = 225
So, Total students in Engineering major = 225×20/18 = 250
According to question
18/225 = x/250 (where x are students from Delhi with Engineering major)
⇒ x = 20
Question 3. 12% of all students are from Chennai. What is the largest possible percentage of economics students that can be from Chennai, rounded off to the nearest integer?
73%
77%
75%
71%
69%
Solution: (A)
Total number of Physics majors = 225
Total number of students = 225 x 100/18 = 1250
Students from Chennai = 12% x1250 = 150
Number of Physics majors from Chennai (from graph) = 40
Maximum possible number of Economics majors from Chennai = 150 - 40 = 110
Maximum Percentage of Economics Major from Chennai = 110 x 100/150 = 73.33%.
Prerequisite:
To prepare Data Interpretation (Pie Chart), a student must learn

Part-3: VARC for CAT 2024 Exam
Topic: Pronoun and Its Type
Pronouns are used in place of nouns to avoid repetition of the nouns to which they refer. Pronouns have different forms and are used in different ways.
Eg: I, me, he, she, they, each, few, many, etc
To understand them in a better way, they are categorized into different categories as shown:
Type | Example | Uses |
Personal Pronoun (Used in place of the name of a person) | I, Me, He, She, You, They, Her, Us etc | He is going to meet her. |
Possessive Pronoun (Shows possession of something) | My, Mine, ours, your, its, hers, etc | This T-shirt is mine. |
Relative Pronoun (used before describing the features or properties of the subject) | That, who, whom, whose, which etc | The thief who stole the money has been successfully punished. |
Reflexive Pronoun (Used when the subject and the object of a sentence are the same) | herself, myself, yourself, yourselves, himself, oneself, etc | He used to believe in himself. |
Intensive Pronoun (Similar to Reflexive pronoun but emphasise more intensely on Subject) | herself, myself, yourself, yourselves, himself, oneself, etc | I myself cook my food. |
Indefinite Pronoun (Used when the subject is not certain) | nobody. anybody everybody, somebody Anyone, no one, everyone, someone etc. | No one is perfect in this world. |
Demonstrative Pronoun (Used to show the closeness of the subject or its position) | This, that, these, such, those, etc. | I had the privilege to visit the Prime Minister’s office, that was worth remembering. |
Interrogative Pronouns (used to ask questions) | What, which, whose, whom, who, etc. | Who is confident enough to clear the CAT this year? |
Reciprocal Pronoun (Used when the sentence has the two actions are performed by two parties) | Each other, one other | The kids threw stones at one another. |
Distributive Pronoun (refers to individuals in a group) | none, each, either, neither, any, everyone, no one etc. | None of our friends was involved in the fighting. |
Questions on Pronouns From CAT Previous Year Papers (CAT VARC pronoun)
Direction- Find the correct alternative for the underlined sentence:
Question 1. My mother bought ice creams for my brother and me, but she didn’t buy one herself.
for my brother and me, but she didn’t buy one for herself.
for my brother and myself, but she didn’t buy herself one.
for my brother and I, but she didn’t buy one for her.
for my brother and I, but she didn’t buy one for herself.
Ans. (A)
Option C and D are wrong because the use of ‘I’ does not make any sense, In place of I, ‘me’ should come (pronoun in place of a noun)
Option B is wrong since ‘myself’ (reflexive pronoun) refers to when I purchased the ice-cream but her mother purchased it.
Therefore, option A is correct because correct pronouns were used.
Question 2. He ____ saw the running Dog.
(a) himself (b) him (c) them (d) themselves
Ans: (a)
The correct pronoun for "he" is himself.
Question 3. Shreeti and ____ went to a movie.
(a) I (b) themselves (c) myself (d) ourself
Ans: (a)
Personal pronouns should be used here. So, the correct answer is option A.
Question 4. When a girl asked how I got _____ address, I told her that it was with the help of a relative of _____.
(a) my/ me (b) mine/ his (c) her/hers (d) she/ she
Ans: (c)
The address here is related to a girl, so "her" should come
Relative to mine or a relative of hers; both can be correct. However according to the options given, option (C) will be correct.

Hello Ashish,
Yes, you can get admission to MBA programs at IISWBM without a CAT score, but only for certain courses. Note that IISWBM has MBA programs under the University of Calcutta and flagship courses like MBA (Day) or MBA-HRM typically require a CAT score. Other programs like the PGDM or Executive MBA/Course may have other entrance examinations on which consideration would be made, or considerations may be based on merit, and of course work experience. Always run any eligibility detail checks with the official IISWBM (https://www.iiswbm.edu/) website or The IISWBM prospectus.

Yes, a state (Delhi) NC-OBC certificate is valid for CAT 2025 , but it must be in the central government format (for appointment to posts under Government of India).
Also, it should be issued after 31st March 2025, as required by IIMs. If your certificate meets these conditions, it will be accepted.
Hope it helps !
Prachi Kumari 28 June,2025
Hello aspirant,
With 375 marks and an AIR of around 2.6 lakh in NEET 2025, getting admission to Ayurvedic & Unani Tibbia College (AUTC), New Delhi under the state quota is quite difficult. The cutoffs for government BAMS seats in AUTC generally stay below AIR 50,000, especially for the General and EWS categories. Your score may not meet the cutoff in the first or second rounds, but you might still have a slim chance in the mop-up or stray vacancy rounds, depending on how many seats remain and how other candidates opt. If you're a Delhi domicile and have all your documents ready, you should definitely apply and fill AUTC as a top choice. It’s also good to keep backup options in other AYUSH colleges open.
OISHEE BANERJEE 01 July,2025
GIBS Business School in Bangalore accepts multiple national and state-level entrance exam scores for admission to its PGDM program. You can apply using scores from exams like CAT, MAT, XAT, CMAT, GMAT, ATMA, or various state-level CETs.
The admission process typically considers your entrance exam score along with your academic record, performance in the group discussion and personal interview, and any work experience you may have. For the BBA program, admissions are generally based on your Class 12 marks and do not require entrance exam scores.
If you're planning to apply, it's a good idea to keep your exam score, academic documents, and personal statement ready for the selection rounds.
OISHEE BANERJEE 24 June,2025
If your son’s first preference is CSE, then Amrita Bangalore clearly leads among the three, simply because CSE opens more doors in terms of placements, internships, and future-proof careers. Amrita is also NAAC A++ and has a strong reputation, especially for CSE. Category 2 is also manageable fee-wise compared to higher categories.
VIT Chennai is a decent campus, and their ECE program is solid, but Category 5 means much higher fees and very low chance of branch upgrade later. CSE at VIT Chennai would have been more competitive here — but ECE at that fee tier is not as strong a deal unless your son has a strong interest in core electronics.
Manipal Bangalore (MIT Bengaluru campus) is a newer campus. ECE there is still developing in terms of placements and faculty compared to the main Manipal campus. Unless your son strongly prefers Bangalore or is getting some advantage here like scholarships or internship access, it doesn't stand out above Amrita.
So, recommendation: Go with Amrita Bangalore CSE (Category 2). It balances a strong branch with a decent campus and better long-term potential in the tech industry. If your son is open to core electronics and you’re okay with the higher cost, VIT Chennai is fine, but still comes second to CSE at Amrita.
All the best!
