Part-1: Quantitative Aptitude for CAT exam

Important Concept/Formula Used in Time, Speed and Distance escalator problems

Time speed distance escalator problems:

  1. Moving ‘with’ the escalator means one has to climb fewer steps on one’s own. (Similar to downstream)

  2. Moving ‘against’ the escalator means one has to climb more steps on one’s own. (Similar to upstream)

  3. Types of Escalator based problems:

  • Length-related questions

  • Time-related questions

  • Steps-related questions

  • Speed-related questions

Previous Year CAT Questions On Time, Speed and Distance (Escalator):

Q1. Rakesh takes 45 seconds on an escalator which is moving down when he walks down but takes 35 seconds when he runs down. He takes 25 steps when he walks whereas he takes 35 steps when he is running. What is the total number of steps in the escalator? [TITA, Based on CAT]

Common escalator problems and solutions:

Let the speed of the escalator be ‘x’ steps per second.

tsd CAT Questions Escalator Trick: The distance covered in going down in both cases should be the same.

Distance covered when he is walking = 25 + 45x (45x is covered by escalator)

Distance covered when he is running = 35 + 35x (35x is covered by escalator)

=> 25 + 45x = 35 + 35x

=> x = 1

Total number of steps = 25 + 45(1) = 70 steps

Time speed distance escalator problems

Q2. Amit and Sumit are climbing on a moving escalator that is going up. Amit takes 40 steps to reach the top whereas Sumit takes 45 steps for the same. Sumit takes 5 steps whereas Amit can take only 4 steps in one second. What is the total number of steps in the escalator? [TITA, Based on CAT]

Common escalator problems and solutions:

tsd CAT Questions Escalator Trick 1: First find the time taken by both to reach the top

For Amit, t = 45/5 = 9 seconds

For Sumit, t = 40/4 = 10 seconds

Let the escalator move with a speed of x steps per second.

tsd CAT Questions Escalator Trick 2: The distance covered in going down in both cases should be the same.

=> 9(5 + x) = 10(4 + x)

=> x = 5 steps per second

Number of steps in the escalator = 9(5 + 4) = 81 steps

CAT Exam:

CAT Previous Year Questions on Venn Diagram :

Q1. A club has 256 members of whom 144 can play football, 123 can play tennis, and 132 can play cricket. Moreover, 58 members can play both football and tennis, 25 can play both cricket and tennis, and 63 can play both football and cricket. If every member can play at least one game, then the number of members who can play only tennis is?

  1. 32

  2. 38

  3. 43

  4. 45

Venn Diagram Questions with Solution: ANS. (3)

According to the information given in the question

1724315106942

Considering that all those who play all their games as X as shown in the above Venn diagram, we will consider Student’s playing football and cricket both as 63-x, Student’s playing football and tennis both will be 58-x and student’s playing cricket and tennis both as 25-x.

Venn Diagram Trick: Firstly, as we know each student is playing at least one game so the addition of all players playing must be equal to the total number of students.

Secondly, as we know student playing game is clearly given in question

So, solution would be like

Only football would be 144-(63-x + x + 58-x) =23+x

Similarly, only tennis would be 123-(58-x+x+25-x) =40+X

Venn Diagram Trick: Students playing all the games must be equal to 256

256= Cricket + only football + only tennis + both football and tennis

256 = 132 + 23+x + 40+x + 58-x

On solving we get

X = 3

So, they have asked for only tennis so we would put x=3 in 40+x

So, answer would be = 40+3=43

Q2. Out Of 60 students in a class, anyone who has chosen to study maths elects to do physics as well. But no one does maths and chemistry, 16 do physics and chemistry. All the students do at least one of the three subjects and the number of people who do exactly one of the three is more than the number who do more than one of the three. What are the maximum and the minimum number of people who could have done Chemistry only?

Venn Diagram Questions with Solution:

Trick for Venn Diagram: According to given information, draw Venn diagram as shown below:

1724315107045

All students studying at-least one subject so

P + M+ C +(P&C) = 60

P+M+C+14 = 60

P+M+C = 44

Trick for Venn Diagram: Apply the given condition in equations formed

The number of people who do exactly one of the three is more than the number who do more than one of the three => Only P + only C must be greater than P&M + 16

So,

Only P + Only C > P&M + 16

The Question needs the answer for maximum and minimum for only C

Since they are asking for maximum and minimum of Only C

The trick is for minimum Put only C as 0 and if this equation holds then minimum would be zero

For maximum put only C as 44 and then check for equation hold or not

So, by putting only C as zero we get

Only P+0 > P&M + 16

Now we can easily see that equation will hold, we can find many values for only P and P&M

Similarly, if we put only C as 44 which is maximum value still the equation will hold so the answer would be

Max = 44 and Min = 0

Part-3: CAT Exam Preparation 2024: CAT exam tips for VARC (Verbal Ability & Reading Comprehension)

CAT Exam Important Topic: Strategy to Prepare “Participles” for CAT-2024

CAT Important Basic Concept

Participles are forms of verbs that can be used as nouns, modifiers, and compound verbs.

CAT Previous Years' Questions on Participles

Find the error in the underlined part:

Question: Due to the slow-moving nature of tectonic plate movement, the oldest ocean crust is thought to date from the Jurassic period, formed from huge fragments of the Earth’s lithosphere and lasted 200 million years. [CAT PYQ]

  1. formed from huge fragments of the Earth’s lithosphere and lasted 200 million years.

  2. forming from huge fragments of the Earth’s lithosphere and lasting 200 million years.

  3. forming from huge fragments of the Earth’s lithosphere and lasted 200 million years.

  4. formed from huge fragments of the Earth’s lithosphere and lasting 200 million years.

Solution: [D]

The “oldest ocean crust” was “formed” in the past during the Jurassic period and is currently still around (since the word ‘oldest’ directed towards its presence, otherwise the word ‘oldest’ would not have been used). We need the past tense/participle verbs to be used correctly.

Option (A): The ocean crust was “formed” in the past” but if “lasted” is past tense then the oldest ocean crust is no longer around.

If you chose (B) or (C), “forming” implies the ‘oldest ocean crust is still being formed. and that part is no longer continuing to form but was formed at some point during the Jurassic period.

Option D is correct.

CAT 2024:

Prerequisite

Tips and Tricks to Solve Venn Diagrams

Venn Diagram questions in the CAT exam appear frequently in the DILR section, testing your ability to understand and organise data involving overlapping sets. With the right techniques and regular practice, you can solve these questions accurately and within time limits.

1. Understand Set Terminology

Tip: Know what union (A ∪ B), intersection (A ∩ B), complement (A′), and subsets mean.

Example: If 40 students like Math (M) and 30 like English (E), A ∪ B = those who like at least one = M + E – M∩E.

2. Start with the Innermost Set

Tip: Begin solving from the part common to all sets (triple intersection in 3-set problems), then move outward.

Example: If 10 students like all three sports—Cricket, Football, and Hockey—place 10 in the intersection of all three circles first before filling other sections.

3. Use Variables for Unknowns

Tip: Assign variables to unknown segments and use given totals to form equations.

Example: If 100 people were surveyed, x like only A, y like A and B, z like all three, create equations:

Total = x + y + z + other regions = 100.

4. Draw Neat, Labelled Diagrams

Tip: Keep the diagram clean with labels for each region (Only A, A∩B, A∩B∩C, etc.).

Example: For a 3-set Venn diagram, label 7 distinct regions. It avoids confusion when plugging in values or solving equations.

5. Practice Common Set Patterns

Tip: Know standard expressions like “Only A” = A – (A∩B + A∩C – A∩B∩C).

Example: If 50 like A, 30 like both A and B, and 10 like all three, then "only A" = 50 – (30 – 10) (A∩C – A∩B∩C).

6. Use Total = A + B + C – (Pairwise Intersections) + (All Three)

Tip: Apply the inclusion-exclusion principle.

Example: If:

  • A = 60

  • B = 70

  • C = 50

A∩B = 30

B∩C = 20

A∩C = 25

A∩B∩C = 15

Then Total = 60 + 70 + 50 – (30 + 20 + 25) + 15 = 120

7. Use Complementary Information Wisely

Tip: Subtract people outside the sets from the total to focus only on those involved.

Example: Out of 200 students, 40 like none of the three subjects. So, only 160 belong inside the Venn Diagram.

Practice and remain focused; Day 35 will be posted tomorrow.

Frequently Asked Questions (FAQs)

1. How do I solve escalator-based CAT questions efficiently?

Visualise escalator problems as relative speed problems. Use the formula: Relative Speed = Speed of person ± Speed of escalator, depending on direction. Practice varied types to build speed and confidence.

2. What’s the best approach to tackle 3-set Venn Diagram puzzles in CAT?

Start from the intersection of all three sets, then fill outward. Use variable substitution for unknowns and apply the inclusion-exclusion principle for accurate calculations and logical deductions.

3. How are participles tested in CAT VARC, and how should I prepare?

Participles aren't tested directly, but knowing them improves grammar and sentence structure understanding. Practice identifying participles in RCs and para jumbles to improve comprehension and sentence flow.

4. Can escalator problems appear as Data Interpretation questions in CAT?

Yes, escalator or TSD-based logic may feature in DI sets. Recognise patterns, extract data efficiently, and apply logical formulas to solve them in time-sensitive environments.

5. Why is mastering participles important for VARC precision?

Participles help identify verbals, clarify sentence intent, and avoid modifier errors in para jumbles and sentence rearrangement. Mastery ensures you spot structural flaws in options with greater accuracy.

Dear Aspirant

Your rank at eleven thousand eight hundred eighty seven under the OBC reservation has a strong chance for admission to the Computer Science Engineering (CSE) program at one of the three CUSAT campuses The exact seat depends on opening and closing ranks for CSE in each campus and the round of counselling

CUSAT campuses offering BTech CSE
• School of Engineering Thrikkakkara – flagship campus in Kochi
• CUCEK Kuttanad – second campus in Alappuzha district
• Lakeside campus does not offer CSE so only two campuses are relevant

Previous closing ranks under OBC quota for CSE
• Thrikkakkara campus closed near rank one thousand
• CUCEK Kuttanad closed around six thousand two hundred in 2024

Your likelihood with rank 11887
• Thrikkakkara campus is unlikely as CSE closes much lower than your rank
• CUCEK has potential since closing ranks in recent years have extended into the high six thousands
• Seats may remain open in later rounds so you may gain admission at CUCEK

Other CSE seat possibilities under OBC
• School of Engineering might open seats in spot or mop up rounds if higher ranked students do not confirm
• CUCEK will likely accept OBC candidates up to rank one two thousand to thirteen thousand
• Keep an eye on real time counselling as closing ranks may shift downward with seat cancellations

Alternative branches and campuses
If CSE is not available at CUCEK you may consider similar branches like Electronics and Communication Engineering Information Technology Mechanical Engineering and Civil Engineering closing beyond twelve thousand under OBC
You may also add interdisciplinary programs or lateral entry courses available in Lakeside or Thrikkakkara depending on available seats

Counselling strategy recommendations
• Register and fill choices on the CUSAT admissions portal in all counselling rounds
• Place CUCEK CSE as a high preference followed by ECE or IT at Thrikkakkara or CUCEK
• Monitor round wise closing ranks through the portal or official communications
• Participate in mop up and spot rounds where seats are more likely available near your rank

Key considerations
• Cutoffs decrease between rounds allowing more opportunities in later phases
• OBC candidates compete within their category reducing competition compared to open rankings
• CUCEK is your best target campus for CSE at your rank under OBC
• You must have all documents ready like previous marksheet category certificate and CUSAT admit card for verification

Let me know if you would like a suggested list of choices tailored to your academic interest or want help tracking counselling round data

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.
