CAT Exam Important Topic: Strategy to Prepare ”Data sufficiency questions for CAT-2024”s

Important Concept/Formula Used in CAT data sufficiency reasoning

Concepts and Formulas Used in CAT data sufficiency reasoning are given below:

Data Sufficiency question, have the answer options which generally feature in this question type:

Give answer (A) if the data in Statement I alone are sufficient to answer the question, while the data in Statement II alone are not sufficient to answer the question.

Give answer (B) if the data in Statement II alone are sufficient to answer the question, while the data in Statement I alone are not sufficient to answer the question.

Give answer (C) if the data either in Statement I or in Statement II alone are sufficient to answer the question.

Give answer (E) if the data in both Statements I and II together are necessary to answer the question.

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.

Tips and Tricks for Flaws and Paradox questions for CAT exam 2024

Hello there,

With a 53 percentile in CAT , the chances of receiving a call from XISS (Xavier Institute of Social Service) may be limited, as their typical cutoff for CAT is generally higher than this, especially for their flagship programs like MBA or PGDM .

However, admission depends on several factors such as:

  1. Academic Profile : Your 10th (67.8%) , 12th (82.5%) , and graduation SGPA (7.5) are decent, and they can contribute positively to your application.

  2. Work Experience/Extra-curriculars : If you have any relevant work experience or strong extra-curricular achievements, it might improve your chances.

  3. Overall Application Strength : XISS also considers your overall profile, including your statement of purpose (SOP) and interview performance .

Though the CAT percentile is a key factor, you might still be considered based on your overall profile if you apply to their PGDM programs . It's always worth checking with the college directly for the specific eligibility criteria and cutoffs for the year you're applying.


I would recommend you to use CAT College Predictor Tool by Careers360 to get the list of possible colleges you can get with your rank.


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.

Hello there,

With a 65 percentile in CAT and belonging to the General category , getting admission to USMS (University School of Management Studies) can be challenging, as their cutoffs are generally higher, typically around 85-90 percentile or more. However, admission can depend on factors like:

  • Category-wise cutoff : Sometimes, the cutoff for the General category can be higher, but you may still apply as there might be specific reservation relaxations or fluctuations based on the number of applicants.

  • Interviews and GD : Even if you meet the minimum cutoff, interviews and group discussions are a mandatory part of the selection process. They assess your communication skills, leadership qualities, and overall fit for the program.

    Recommendations:

  1. Check the official cutoff for USMS for your specific year.

  2. Prepare for interviews : It is likely that you will have to appear for the next rounds if you qualify. Preparing well for the interview is important, as it can make a difference in your selection.

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. 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.
