CAT Previous Years Questions On Complex Numbers

Q1. CAT 2023 complex numbers Questions and Answers are given below:

If z is a complex number, then the minimum value of |z- 1| + |z + 1| is ______.

[Based on MBA Entrance Exams]

CAT complex numbers problems with solutions are given below:

Solution:

If z = a+ ib

Then, |z- 1| = a-12+b2

and |z + 1| = a+12+b2

|z- 1| + |z + 1| = a-12+b2 + a+12+b2

This value is minimum if either a= 1 and b =0 or a =0 and b = 1

So, the minimum value of |z- 1| + |z + 1| = 2.

Q2. Complex numbers Questions with solutions are given below:

If the cube roots of unity are 1, ω, ω2, then find the roots of the equation (x − 1)3 + 64 = 0. where ω = 3-1 [Practice Question]

Complex numbers system problems with answer for CAT exam are given below:

Solution:

(x − 1)3 = −64 ⇒ x − 1 = (−64)1/3

CAT Practice Questions on Statements and Conclusions (critical reasoning questions for CAT)

Question 1: Statements and Conclusions (critical reasoning questions for CAT) are given below:

Read the passage and answer the questions based on it. (CAT 2017)

Typewriters are the epitome of a technology that has been comprehensively rendered obsolete by the digital age. The ink comes off the ribbon, they weigh a ton, and second thoughts are a disaster. But they are also personal, portable and, above all, private. Type a document and lock it away and more or less the only way anyone else can get it is if you give it to them. That is why the Russians have decided to go back to typewriters in some government offices, and why in the US, some departments have never abandoned them. Yet it is not just their resistance to algorithms and secret surveillance that keeps typewriter production lines - well one, at least - in business (the last British one closed a year ago). Nor is it only the nostalgic appeal of the metal body and the stout well-defined keys that make them popular on eBay. A typewriter demands something particular: attentiveness. By the time the paper is loaded, the ribbon tightened, the carriage returned, the spacing and the margins set, there's a big premium on hitting the right key. That means sorting out ideas, pulling together a kind of order and organising details before actually striking off. There can be no thinking on screen with a typewriter. Nor are there any easy distractions. No online shopping. No urgent emails. No Twitter. No need even for electricity - perfect for writing in a remote hideaway. The thinking process is accompanied by the encouraging clack of keys, and the ratchet of the carriage return. Ping!

Question. Which one of the following best describes what the passage is trying to do?

  1. It describes why people continue to use typewriters even in the digital age.

  2. It argues that typewriters will continue to be used even though they are an obsolete technology.

  3. It highlights the personal benefits of using typewriters.

  4. It shows that computers offer fewer options than typewriters.

Ans: [1]

Explanation:

The author is trying to explain:

why the typewriter continues to be used even in today's digital age. For this, he has given reasons that typewriters are personal and private and cannot be hacked. These can be used anywhere without the requirement of electricity.

Q2. CAT exam 2023 statements and Conclusions questions with solutions are given below:

Comprehension: [CAT 2018]

[The] Indian government [has] announced an international competition to design a National War Memorial in New Delhi, to honour all of the Indian soldiers who served in the various wars and counter-insurgency campaigns from 1947 onwards. The terms of the competition also specified that the new structure would be built adjacent to the India Gate – a memorial to the Indian soldiers who died in the First World War. Between the old imperialist memorial and the proposed nationalist one, India’s contribution to the Second World War is airbrushed out of existence.

The Indian government’s conception of the war memorial was not merely absent-minded. Rather, it accurately reflected the fact that both academic history and popular memory have yet to come to terms with India’s Second World War, which continues to be seen as little more than mood music in the drama of India’s advance towards independence and partition in 1947. Further, the political trajectory of the postwar subcontinent has militated against popular remembrance of the war. With partition and the onset of the India-Pakistan rivalry, both of the new nations needed fresh stories for self-legitimisation rather than focusing on shared wartime experiences.

However, the Second World War played a crucial role in both the independence and partition of India. . . . The Indian army recruited, trained and deployed some 2.5 million men, almost 90,000 of which were killed and many more injured. Even at the time, it was recognised as the largest volunteer force in the war. . . .

India’s material and financial contribution to the war was equally significant. India emerged as a major military-industrial and logistical base for Allied operations in Southeast Asia and the Middle East. This led the United States to take considerable interest in the country’s future and ensured that this was no longer the preserve of the British government.

Other wartime developments pointed in the direction of India’s independence. In a stunning reversal of its long-standing financial relationship with Britain, India finished the war as one of the largest creditors to the imperial power.

Such extraordinary mobilization for war was achieved at a great human cost, with the Bengal famine the most extreme manifestation of widespread wartime deprivation. The costs on India’s home front must be counted in millions of lives.

Indians signed up to serve on the war and home fronts for a variety of reasons. . . . [M]any were convinced that their contribution would open the doors to India’s freedom. . . . The political and social churn triggered by the war was evident in the massive waves of popular protest and unrest that washed over rural and urban India in the aftermath of the conflict. This turmoil was crucial in persuading the Attlee government to rid itself of the incubus of ruling India. . . .

Seventy years on, it is time that India engaged with the complex legacies of the Second World War. Bringing the war into the ambit of the new national memorial would be a fitting – if not overdue – recognition that this was India’s War.

Question: In the first paragraph, the author laments the fact that

  1. the new war memorial will be built right next to India Gate.
  2. there is no recognition of the Indian soldiers who served in the Second World War.
  3. funds will be wasted on another war memorial when we already have the India Gate memorial.
  4. India lost thousands of human lives during the Second World War

Ans: [2]

In the first paragraph, the author says that ‘India’s contribution to the second world war is airbrushed out of existence.’ This means, there is no recognition of the Indian soldiers’ contribution to the second world war.

Frequently Asked Questions (FAQs)

1. What are Complex Numbers?

In mathematics, a complex number is an element of a number system that extends the real numbers with a particular element labeled i, known as the imaginary unit, and satisfies the equation; every complex number may be represented in the form a+bi, where a, and b are real numbers.   

2. Why is this topic important for the CAT exam?

Complex numbers are those that have both real and imaginary parts. Complex number problems on the CAT examine your knowledge of equations and mathematics. Knowing this subject may help you answer difficult problems quickly, which is critical for scoring well.

3. How can I distinguish between Complex Numbers and Quadratic Equations?

Many candidates mix up complex numbers with quadratic equations. To prevent misunderstanding, review each subject independently and understand their distinct features. Practice answering a lot of questions for more clarity.

4. How can I answer the complex number and Calendar Questions quickly?

Here are some useful tips. For complex numbers, concentrate on learning crucial formulae and learning shortcuts to save time. For calendar questions, master particular strategies such as determining the day of the week for a given date. Regular practice will help you become more efficient and accurate.

5. How can previous year's questions (PYQs) help me with the reasoning section of CAT?

PYQs help you understand the sorts of questions that have previously been asked, as well as their degree of complexity. Solving these will give you an idea of what to anticipate and help you prepare for similar critical thinking questions on the CAT Exam.

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.

You Got This !


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

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. 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 :
