CAT exam 2024:

Data Sufficiency In Quantitative Aptitude: CAT Previous Years Questions On Data Sufficiency

General Instructions for Data Sufficiency Questions for CAT exam:

Choose option A: If Statement 1 ALONE is sufficient; statement 2 is not sufficient

Choose option B: If Statement 2 ALONE is sufficient; statement 1 is not sufficient.

Choose option C: If Statements 1 & 2 TOGETHER are sufficient but are not sufficient independently.

Choose option D: If Each statement is INDEPENDENTLY sufficient.

Choose option E: If Statements together are NOT sufficient. Additional data is required.

Q1. Is the positive integer P prime?

Statement 1: 2P+1 is prime

Statement 2: P - 8 is a perfect square less than 25 [CAT Level]

  1. A

  2. B

  3. C

  4. D

  5. E

Solution: C

Statement 1: 2P+1 is prime

Prime numbers are 2, 3, 5,7, 11, 13, 17, …….

If 2P+1 = 3, then P = 1 which is not a prime number.

If 2P+1 = 5, then P= 2 which is a prime number.

If 2P+1 = 7, then P= 3 which is a prime number.

If 2P+1 = 11, then P= 5 which is a prime number.

We can never get a prime number further.

So, we cannot say that the P is a prime or not.

Therefore, statement 1 is not sufficient.

Statement 2:

P - 8 is a perfect square

i.e. P- 8 = x2, where x is a positive integer.

So, P = x2 + 8

If x2 =1, then P= 9 is not a prime

x2 = 4, then P = 12 is not a prime number

x2 = 9, then P =17 which is a prime number.

x2 = 16, then P =24 which is a prime number.

So, we cannot say that the P is a prime or not.

Therefore, statement 2 is not sufficient.

Combined 1 and 2:

We are not getting any common solution. So, we will say there is no such Prime number.

Therefore, we can say our answer is “No”. Hence, both statements together are sufficient to answer the question.

The answer is option ‘C’.

Q2. What is n (n is an integer)?

Statement 1: n > 10

Statement 2: n2 < 144 [Practice Question: Easy]

  1. A

  2. B

  3. C

  4. D

  5. E

Solution: C

Statement 1: n> 10, n can be anything greater than 10.

No unique answer.

Therefore, statement 1 is not sufficient.

Statement 2:

n2 < 144

n= 11, 10, 9, …

n= -11, -10, -9, …

Therefore, statement 2 is not sufficient.

Combined 1 and 2:

We have a unique value in common i.e.. n =11.

The answer is option ‘C’.

Tricks and Tips for CAT questions on data sufficiency problems

Find the CAT tips and tricks for Data Sufficiency Questions below:

  1. Never assume anything on your own.

  1. Be careful while answering questions like

Is the value of x can be calculated?”

When we get the answer to the question as 'No', we tend to mark the answer as Data Insufficient. But, even 'no' is an answer in some cases and this might mean that the data is sufficient

  1. Carefully read the directions.

  1. We need not solve the question completely. We must find out whether the answer can be calculated or not.

  1. Practise Previous years questions to get familiar with the types of questions being asked.

CAT Exam Important Topic: Strategy to Prepare “Flaws and Paradox” (Critical Reasoning) for CAT-2024

Important Concept of CAT Flaws and Paradox (Critical Reasoning questions)

The concepts used in Flaws and Paradox CAT questions are given below:

Paradox question contains two seemingly contradictory statements and you were asked to resolve the discrepancy.

Format of question is generally as follows:

Which of the following, if true, would best explain the discrepancy above?

Or

Which of the following, if true, would best resolve the paradox?

CAT Practice Questions on Flaws and Paradox (critical reasoning questions for CAT)

Flaws and Paradox CAT Sample Question:

A recent archaeological expedition in the American sub-continent revealed many skeletons of animals that were supposed to die about thousands of years ago. Further research suggested that all the skeletons had been exposed to temperatures in excess of 600 degrees Kelvin. This fact provided grounds for speculation that they were killed and cooked by local tribes at that time. However, some of the skeletons belonged to animals that were considered sacred by those tribes and were never hunted or eaten.

Which of the following best explains the apparent discrepancy above?

  1. Some of the skeletons found during the expedition belonged to animals that no longer inhabit the area.
  2. Skeletons of most animals did not have damages typical of the skeletons of animals that had been killed, cut, and cooked.
  3. Tribes that inhabited the American sub-continent 1000 years ago used fire to cook food.
  4. Another study indicated that there was a great famine in the American sub-continent at that time, which forced local tribes to look for alternative sources of food.
  5. A further study indicated evidence of a large fire that had occurred in the American sub-continent approximately 1000 years ago.

Solution and Strategy for Flaws and Paradox(critical reasoning questions for CAT) are given below:

CAT Strategy 1: Identify the paradox.

Studies revealed that animals were killed and cooked.

Studies also revealed that some skeletons belonged to those animals which were considered sacred.

These are the two contradicting statements. (Paradox)

CAT Strategy 2: Changing a paradox into a simple problem.

One can ask a simple question:

“Why were the scared animals exposed to a temperature in excess of 600-degree kelvin?”

CAT Strategy 3: Elimination of choices that have no relevance:

Go through each option:

Option (1): does not make any sense.

Option (2): Increasing the paradox.

Option (3): It does not answer the question.

Option (4): It does not explain the burning of sacred animals.

Option (5): In a fire, all animals will be burnt irrespective of their sacredness. Hence resolving the paradox.

Questions related to CAT

Have a question related to CAT ?

Although, it's very unlikely that you will secure a seat in top ABM with CAT 67 percentile. Here's is a breakdown to your question:

· CAT Percentile vs. Score: A CAT score of 67 typically translates to a percentile in the range of 90-95 percentile based on the provided data from previous years. While this is a decent score overall, it falls short of the cutoffs for most top-tier ABM programs.

· Cutoffs for Top ABM Institutes:

  • IIM Lucknow: For their PGP-ABM program, the qualifying CAT cutoff for the general category is around 85 percentile . However, the actual cutoff for shortlisting for the Written Ability Test (WAT) and Personal Interview (PI) stages is likely to be higher.
  • IIM Ahmedabad: While they also offer an ABM program (PGP-FABM), their minimum qualifying CAT cutoff is around 80 percentile , but the final admission cutoffs are usually much higher, often in the 99+ percentile range for general candidates.
  • MANAGE (National Institute of Agricultural Extension Management): Their cutoff in CAT percentile has been around 70 for the general category in recent years. With a 67 percentile, you might have a slim chance here, but it's still competitive.
  • CCS NIAM (National Institute of Agricultural Marketing, Jaipur): They consider CAT scores with a significant weightage (30-51% in their selection criteria). While they don't explicitly state a cutoff, it's reasonable to assume it would be higher than 67 percentile for a good chance of admission.

· Overall Good CAT Score: Generally, a CAT percentile of 90 and above is considered a good score for securing admission to decent MBA programs in India. For top-tier institutes, a percentile of 95 and above is often preferred.

· MBA Colleges Accepting 60-70 Percentile: While there are MBA colleges that accept CAT scores in the 60-70 percentile range, these are generally not the top-ranked or most sought-after ABM programs. The focus of those lists is on general MBA programs, not specifically ABM.

While securing a seat in ABM can be tough, you can research about other colleges, consider other examinations, to improve your application profile.

Hello,

achieving a 99.99 pecentile in the CAT exam significantly enhances your prospects for admission to JBIMS, which evaluates candidates using an application rating(AR) score, which includes

-entrance exam score (CAT/MH-CET/CMAT) : 60% weightage

-Past Academic Record (PAR) : 15% weightage (https://cracku.in/colleges/jbims/admission-process/?utm_source=chatgpt.com)

-Extra-curricular Activities/Work Experience : 20% weightage (https://jbims.edu/uploads/announcement/Revised_M_Sc__Finance_Admission_Procedure_Batch_2024-26.pdf?utm_source=chatgpt.com)

-Diversity (Academic/Gender): 5% weightage

while ahigh CAT percentile is crucial, a lower academic record may impact your overall AR score. Nonetheless, exceptional performance in other areas, such as entrance exams and extracurricular activities, can help offset weaker academic credentials. it's advisable to review JBIMS's detailed admission criteria and consider strengthening other aspects of your application to enhance your chances


To find the 2024 MHT CET answer key, you'll need to check the official Maharashtra State Common Entrance Test Cell website. This is the primary source for all official announcements and documents related to the MHT CET exam. After the exam concludes, the CET Cell typically releases a provisional answer key.

Once released, the provisional answer key will likely be available as a downloadable PDF file. You'll need to navigate to the official website, look for the MHT CET section, and find the link related to the answer key. This link might be labelled "MHT CET 2024 Answer Key" or something similar.

After downloading the answer key, you can compare your responses with the official answers. If you find any discrepancies or have objections, the CET Cell usually provides a window for raising objections. You'll likely need to pay a specified fee for each objection raised. The official website will provide instructions on how to submit your objections, which may involve logging into your candidate portal and following the provided steps.

Finally, after considering all objections, the CET Cell will publish a final answer key. This final version is considered definitive, and the MHT CET results will be based on it. Keep an eye on the official website for all updates and announcements regarding the 2024 answer key.


I hope this helps.




Greetings! Here's a detailed response to your query

Okay, so you're a bit confused about what to put in those CAT, FMS, DSE, and IIFT forms regarding your 12th scores. Since you did CBSE, they usually only consider your final 12th standard marks.

Even though you did great in 11th, scoring 495 out of 500, for these entrance exam forms, they're specifically asking about your 12th board exam marks .You mentioned you got 400 out of 500 in 12th, which comes out to 80%.

Therefore, when filling out the forms for CAT, FMS, DSE, and IIFT, you should enter 80% as your 12th percentage. The aggregate of 11th and 12th isn't typically what they're looking for in these sections. They want to know how you performed in your final board exams. So, stick with the 80% from your 12th results. Good luck with your applications!

Greetings! Here's a detailed response to your query:-

Determination of the best time to start the journey of CAT examination is based on individual factors like your current skill level, knowledge ,potential, learning pace and availability. To give yourself the best chance of success on the CAT exam , which usually takes place in November, it's advisable to begin studying between January and March of that same year. This 8 to 12-month preparation window is widely recommended by experts. But if you're managing your college along with the CAT preparations make sure you start from 2nd year onwards. It will hep you manage stress and you'll have ample amount of time to get along with the syllabus , pattern and various practice and mocks .

You'll be able to build a strong foundation in each sections and be able to know your strengths and weaknesses in different topics. The CAT syllabus is extensive, and early preparation allows for thorough coverage. Assess your learning speed and adjust your preparation timeline accordingly.

Essentially, while the ideal start time is subjective, beginning your CAT preparation well in advance is generally considered the most effective strategy for achieving optimal results.

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.

The fryer did not need anyone to attend to it, and the time to put in the raw ingredients could be neglected.
