Important Concept/Formula Used in sequence and series questions for CAT

Concepts and Formulas used in sequence and series problems and solutions are given below:

  1. Arithmetic Progression (AP)

BIMTECH PGDM Admissions 2025

AACSB Accredited | Highest CTC: 24.43 LPA | Application Deadline: 31st December 2024

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

nth term of A.P. given by an = a+ (n-1)d

Sum of n terms of an AP

Sn = n/2 {2a + (n-1) d} or n/2 {first term + last term}

Arithmetic mean is (a+ an)/2.

Here, a is the first term, d (=a2- a1) is a common difference and n is the number of terms in AP.

  1. Geometric Progression (GP)

CAT 2024 Percentile Predictor
Students can predict their overall performance by using CAT 2024 Percentile Predictor tool before the declaration of the actual result.
Try Now

nth term of the G.P. is an = ar(n-1)

Sum of n terms of a GP

Sn = a{(1- rn)/(1-r)}

sum of an infinite G.P. is given by

S = a/1-r

Geometric Mean of a & b is (ab)1/2.

Here, a is the first term, r (=a2/a1) is the common ratio and n are numbers of terms in GP.

  1. Harmonic Progression (HP)

Nirma University MBA Admission 2025

If a, b, c are in AP, then 1/a, 1/b, 1/c are in HP.

Solve HP with the help of AP.

CAT Sequence And Series Previous Year Questions:

Q1. Sequence and Series Questions for CAT Exam are given below:

Three positive integers x, y and z are in arithmetic progression. If y − x > 2 and xyz = 5(x + y + z), then z − x equals [CAT 2021, slot 2]

  1. 8
  2. 10
  3. 14
  4. 12

Sequence and series questions and answers are given below:

Solution: [3]

If x, y and z are in AP, then

y- x = z- y > 2 (Given)

So, y > x +2 and z > y+ 2; z > x+ 4

Also, x+ z = 2y

It is given that

xyz = 5(x + y + z)

⇒ xyz = 5(3y)

⇒ xz = 15 and z > x+ 4

If z = 15, x = 1 (z > x+ 4, true)

If z = 5, x =3 (z > x+ 4, false)

Therefore z =15 and x= 1 will be taken and the difference is 14.

Q2. Sequence and Series Questions for CAT are given below:

For a sequence of real numbers x1, x2, ..., xn, if x1 - x2 + x3 - ... + (-1)n + 1xn = n2 + 2n for all natural numbers n, then the sum x49 + x50 equals [CAT 2021, Slot 2]

  1. 2
  2. -2
  3. 200
  4. -200

CAT questions on sequence and series are given below:

Answer: [2]

Sn = if x1 - x2+ x3 - ... + (-1)n + 1xn = n2 + 2n

If n = 50; S50 = 502+ 2 x 50 = 2600 = x1 - x2 + x3 - ... + x49 -x50

S49 = 492+ 2 x 49 = 2499 = x1 - x2 + x3 - ... + x49

So, S50 = S49 - x50

⇒ x50 = S49 - S50 = 2499 – 2600 = -101

S48 = 482+ 2 x 48 = 2400

Similarly, x49 = S49 – S48 = 2499 – 2400 = 99

So, x49 + x50 = -101 + 99 = -2

CAT 2024 Syllabus Topic: Strategy to prepare “Picking of Coins” for CAT

Important Concept/Formula Used in questions on coins

  1. These problems are basically a special type of D.I. problems which require a high level of understanding.

  2. There are basically two types of scenarios in these Questions.

  3. The first case is who picks last wins the game

  4. Second case is who picks last loses the gam

  5. For the first case, the person who picks last wins must left (MINIMUM PICK +MAXIMUM PICK) *k coins on the table to ensure it wins.

  6. In the second case, the person who picks last loses. So, the person who picks first must left(MINIMUM PICK +MAXIMUM PICK) *k+ 1) coins on the table to ensure it’s winning.

CAT Previous Years Questions on Coins from the CAT Exam (Coins LRDI questions for CAT):

Q1. Two smart players A and B are playing a coin game in which they can pick up 1, 2, 3, or 4 coins. They have 78 coins and the player who picks the last coin will lose the game. A and B play alternately and A plays the first move. How many coins should A pick at first so his win is independent of the number of coins B picks in his first move?

[CAT PYQ]

Solution:

As the question explained, A is the first picker so he needs to maintain a such number of coins on the table that after his first pick his winning doesn't depend on the coins picked up by B.

So, in such cases, the trick is to maintain (multiple of a sum of minimum pick + maximum pick on the table)

So, the person who has the chance to pick first must pick as many numbers of coins so on the table the coins left on the table must be

(Multiple of the sum of minimum pick + maximum pick on the table)

So if this question the sum of minimum pick + maximum pick would be (1+4)k=5k

must leave on the table so the first person will pick 3 coins from the table and left 75 coins on the table for another person so he will ensure his win.

Q2. An old woman had the following assets: [CAT 2017]

Rs. 70 lakh in bank deposits

1 house worth Rs. 50 lakh

3 flats, each worth Rs. 30 lakh

a certain number of gold coins, each worth Rs. 1 lakh

She wanted to distribute her assets among her three children; Neeta, Seeta and Geeta. The house, any of the flats or any of the coins were not to be split. That is, the house went entirely to one child; a flat went to one child and similarly, a gold coin went to one child.

The value of the assets distributed among Neeta, Seeta and Geeta were in the ratio of 1:2:3, while the gold coins were distributed among them in the ratio of 2:3:4. One child got all three flats and she did not get the house. One child, other than Geeta, got Rs. 30 lakh in bank deposits.

How many gold coins did the old woman have?

  1. 72
  2. 90
  3. 180
  4. 216

Ans: [B]

Let the old woman have ‘x’ gold coins.

herefore, total asset base = Rs. 70 lakhs + Rs. 50 lakhs + Rs. 3 * 30 lakhs + x = Rs 210 lakhs + x

The assets were distributed in the ratio of 1:2:3. So, 210 +x should be multiple of 6.

Since there are “x” gold coins, then the total 210 + x is a multiple of 6.

210 is a multiple of 6. So, x is a multiple of 6.

Also, the gold coins were distributed in the ratio of 2:3:4. So, gold coins should be multiple of 9 also. Therefore, from the above two conclusions, we can say that gold coins are multiple of 18.

Therefore, x is a multiple of 18.

The total value of assets can be taken as 210 + 18k.

Dividing this in the ratio of 1:2:3 among Neeta, Seeta and Geeta.

Neeta = 1/6 x (210 + 18K) = 35 + 3k = 35 – k + 4k

Seeta gets = 2/6 x (210 + 18K) = 70 + 6k

Geeta gets = 3/6 x (210 + 18K) = 105 + 9k = 105+ k + 8k

Discuss for Geeta, the one only who can get three flats worth Rs 90 lakhs

Geeta will have a house of worth Rs 50 lakh, So, she cannot get Rs 30 lakh Cash.

Neeta will get 30 lakhs bank deposits, she will get (5+ 3k) gold coins.

Neeta got a total (35 – k) + 4k worth of assets. So, k = 5.

Neeta = 30 lakhs deposit and 20 gold coins

Seeta = One house + Rs. 20 lakh in bank deposits + 30 gold coins.

Geeta = 3 flats + Rs. 20 lakh in bank deposits + 40 gold coins.

Therefore, the total no. of gold coins = 20 + 30 + 40 = 90.

Tips/Tricks for CAT questions on coins

  • These are special types of problems, so these must be practised before exams.

  • All different types of cases needed to be covered by aspirants because every case required a unique approach to solve this question.

CAT Exam Important Topic: Strategy to Prepare “Statement and Arguments” (What is Critical Reasoning in CAT) for CAT-2024

Important Concept used in Statement and Arguments questions

  • Statement: A statement is defined as that which is
  • expressible by a sentence and is either true or false.
  • Argument: An argument is a dispute or debate. In logic, the term has a more technical meaning.

CAT Previous Years Questions on Statements and Arguments (critical reasoning questions for CAT)

Q1. Statements and Arguments are given below:

Statement: Should military training be made compulsory in our country? [PYQ]

Arguments:

1. Yes, every child should go through this training

2. No, it is not compulsory in USA

  1. If only argument I is strong.

  2. If only argument II is strong.

  3. If either I or II is strong.

  4. If neither I nor II is strong.

  5. If both I and II are strong.

Statements and Arguments questions with solutions are given below:

Ans. Option D

Explanation:

Argument 1: Not every child is strong enough physically. So, it is not a strong argument.

Argument 2: USA is a different country at different levels. Comparison is done here so it is also a weak argument.

Q2. Statements and Arguments (critical reasoning questions for CAT) are given below:

Statement: Should powerful nations attack relatively weaker nations which pose a probable danger to world peace? [IPMAT 2020]

Arguments:

  1. Yes. War is justified for the noble purpose of peacekeeping.

  2. No. War/violence should never be resorted to.


  1. If only 1 is implicit

  2. If only 2 is implicit

  3. If either assumption 1 or 2 is implicit

  4. If neither assumption 1 nor 2 is implicit

Ans: [A]

Explanation:

If someone is dangerous to humankind, it should get eliminated by a stronger person. So, Argument I seem to be implicit.

Tips and Tricks for CAT questions on Statement and Arguments


  1. The criterion of being either true or false is one thing that served to identify the informative use of language.

  1. An argument is a set of at least two statements, one of which is the conclusion of the argument, and the rest of which are premises offered in support of the conclusion.

  1. An argument will often contain indicator words that help identify the premises and conclusion.

  • Some conclusion indicators are:

So/, therefore,/consequently/ as a result/thus/hence/accordingly/it follows that

  • Some Premise indicators are:

Since/because/for/in light of/in view of/as shown by.

  1. Identify strong arguments and weak arguments

Strong Arguments Includes:

  • Facts based on experience

  • Educational development

  • Universal truth etc

Weak Arguments Include:

  • over exaggeration

  • Involves Comparison

  • Half explained arguments

  • Contains words like Each, Nothing, Very, All, only etc

CAT 2024: Pre-requisite to Statement and Arguments

  1. Knowledge of basic components of statements and arguments.

  2. Sentence Structure.

Questions related to CAT

Have a question related to CAT ?

A score of 64 marks in CAT would likely fall around the 85th percentile depending on the difficulty of the exam and the overall performance of candidates in this year.


So,it is highly unlikely that you will receive a call from any of the IIMs as the required percentile for an IIM call is typically much higher, usually ranging from 90% and above, especially for top IIMs like Ahmedabad, Bangalore, and Calcutta.


If you are looking for MBA programs, consider exploring other B-schools that may have lower cut-offs for admission.


Here are some B-schools that may have lower cutoffs for admission:


SOIL Institute of Management: Has a CAT cut-off of 75 percentile


T. A. Pai Management Institute (TAPMI), Manipal: Has an expected CAT cut-off of 85+


Great Lakes Institute of Management (GLIM): Has an expected CAT cut-off of 85+


MICA: Has an expected CAT cut-off of 85+


S.P. Jain Institute of Management and Research (SPJIMR), Mumbai: Has a CAT cut-off of 85 percentile


Shailesh J. Mehta School of Management (SJMSOM), Mumbai: Has a CAT cut-off of 97.5 percentile


Others are IIT Bombay, IIT Kharagpur, IIT Roorkee, JBIMS, XIMB, and GIM.


Now coming to your academic background which often calculated as a weighted average based on the importance of each component different b school has different criteria for it.

CAT PREDICTOR TOOL


To get admission into the NAARM MBA program , which is officially called a PGDM-ABM (Post Graduate Diploma in Management - Agri Business Management), candidates need to apply online, take the CAT or CMAT entrance exam, followed by a shortlisting based on their scores, and then appear for a Group Discussion (GD) and Personal Interview (PI) on campus; the final selection is based on a combination of their entrance exam score, performance in GD/PI, and academic record, with a strong emphasis on agricultural business related skills and experience.

Reservation criteria is same here as other MBA colleges set by government of india i.e

Scheduled Caste (SC): 15% of seats

Scheduled Tribe (ST): 7.5% of seats

Economically Weaker Section (EWS): 10% of seats

Other Backward Classes (NC-OBC): 27% of seats for candidates belonging to the “non-creamy” layer

The CAT cutoff percentiles for the 2024-26 PGDM-ABM batch at the ICAR-National Academy of Agricultural Research and Management (NAARM) are as follows:

General: 75.14

EWS: 38.00

NC-OBC: 44.16

SC: 72.980

for a NAARM MBA PREPARATION interview (specifically their PGDM Agri-Business Management program), focus on thoroughly researching NAARM's curriculum, emphasizing your agricultural background and business acumen, practicing answers to common MBA interview questions, and showcasing your passion for the agri-business sector, while also being ready to discuss your career goals aligned with NAARM's focus on rural development and sustainable agriculture practices.be genuine with your answers.

Hello Varun,

Based on your CAT raw score and profile, here's a breakdown of your potential calls and your chances for different institutes:

1. GIM Goa, GLIM Chennai, IMT Ghaziabad, IMI Delhi:

  • GIM Goa : With a score of 55, GIM typically looks for candidates with a higher percentile. However, you may still get a call if your overall profile, including your academic background (93.8% in Class 12, work experience), is strong.

  • GLIM Chennai : GLIM has a competitive cutoff, but with a solid academic record and work experience, there may be a chance, especially if you belong to a diverse background.

  • IMT Ghaziabad : Your chances with a score of 55 are slim, as IMT usually looks for a higher percentile. However, if you have an impressive profile and high academic scores, there may still be a slim possibility.

  • IMI Delhi : Similar to IMT, IMI Delhi has high cutoffs and competitive selection criteria. However, work experience and other factors like diversity can sometimes offset a lower CAT score.

    2. IIM SAP (Special Admission Program) :

  • The IIM SAP is typically for candidates with significant work experience or other unique factors. Your 14 months of work experience could be beneficial, but your CAT score of 55 is on the lower side, making it unlikely to receive an IIM SAP call. However, if you have other outstanding features in your profile (e.g., exceptional academic performance, leadership qualities, etc.), you might still stand a chance.

    3. Other Possible Calls :

  • UPES Dehradun : Known for considering work experience and unique profiles, UPES could be a potential option for you.

  • Bimtech Noida : You could expect a call here, considering your work experience and overall profile.

  • XIMB Bhubaneswar : This institute also considers profiles with good work experience, and you may stand a chance despite your score.

Overall, you can expect a call from institutes that weigh work experience and academic performance heavily, but you should also be prepared for lower-tier institutes in terms of CAT score cutoffs. Ensure you target institutes that match your profile for better chances.


I hope this answer helps you. If you have more queries then feel free to share your questions with us we will be happy to assist you.

Thank you and wishing you all the best for your bright future.

Two friends Moloy and Niloy passed out from the Purulia Institute of Science and Technology with B.Tech degrees in Mechanical Engineering, but even after a year placement was hard to find. So they decided to take the challenge head-on, came down to Kolkata, rented a garage space on Park Street, and having an affinity towards making people enjoy good food, started their firm named 'B.Tech Bread-Omlette Wala'. 

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.
