Solution:
The difference in sales is given by:
February to January: 15,000 - 10,000 = 5,000
March to February: 40,000 - 15,000 = 25,000
April to March: 25,000 - 40,000 = -15,000 (This is a drop in sales)
May to April: 35,000 - 25,000 = 10,000
June to May: 30,000 - 35,000 = -5,000 (This is a drop in sales)
The greatest improvement in sales is observed in March, where sales increased by 25,000 compared to the previous month, February. So, the greatest improvement was seen in March.
2. In which month was the greatest dip seen?
February
May
April
June
Solution:
The difference in sales is given by:
February to January: 15,000 - 10,000 = 5,000
March to February: 40,000 - 15,000 = 25,000
April to March: 25,000 - 40,000 = -15,000 (This is a drop in sales)
May to April: 35,000 - 25,000 = 10,000
June to May: 30,000 - 35,000 = -5,000 (This is a drop in sales)
Therefore, the greatest dip is observed in April, where sales decreased by 15,000 compared to the previous month, March. So, the greatest dip was seen in April.
3. What is the ratio of total sales in the first three months to total sales in the last three months?
13:18
18:13
1:3
3:1
Solution:
Total Sales in the First Three Months:
January: $10,000
February: $15,000
March: $40,000
Total Sales in the First Three Months = 10,000 + 15,000 + 40,000 = 65,000
Total Sales in the Last Three Months:
April: $25,000
May: $35,000
June: $30,000
Total Sales in the Last Three Months = 25,000 + 35,000 + 30,000 = 90,000
Ratio = Total Sales in the First Three Months / Total Sales in the Last Three Months
Ratio = 65,000 / 90,000
So, the ratio of total sales in the first three months to total sales in the last three months is 13:18.
4. Find the average sales in dollars
$15,000
$25,000
$20,000
$25,833.33
Solution:
Given,
January: 10,000
February: 15,000
March: 40,000
April: 25,000
May: 35,000
June: $30,000
Total Sales = 10,000 + 15,000 + 40,000 + 25,000 + 35,000 + 30,000 = 155,000
Number of Months = 6
Now, calculate the average sales:
Average Sales = Total Sales / Number of Months
Average Sales = 155,000 / 6
Average Sales = 25,833.33 (rounded to two decimal places)
So, the average sales in dollars is approximately 25,833.33.
5. Find the difference between the month that had the highest sales and the month that had the least.
$25,000
$40,000
$5,000
$30,000
Solution:
Given the sales in dollars:
March had the highest sales with $40,000.
January had the least sales with $10,000.
To find the difference:
Difference = Sales in March - Sales in January
Difference = 40,000 - 10,000
Difference = $30,000
So, the difference between the month with the highest sales (March) and the month with the least sales (January) is $30,000.

The candidates can refer to a few CAT DILR questions from last year's examination.
The air-conditioner (AC) in a large room can be operated either in REGULAR mode or in POWER mode to reduce the temperature.
If the AC operates in REGULAR mode, then it brings down the temperature inside the room (called inside temperature) at a constant rate to the set temperature in 1 hour. If it operates in POWER mode, then this is achieved in 30 minutes.
If the AC is switched off, then the inside temperature rises at a constant rate so as to reach the temperature outside at the time of switching off in 1 hour.
The temperature outside has been falling at a constant rate from 7 pm onward until 3 am on a particular night. The following graph shows the inside temperature between 11 pm (23:00) and 2 am (2:00) that night.

The following facts are known about the AC operation that night:
The AC was turned on for the first time that night at 11 pm (23:00).
The AC setting was changed (including turning it on/off and setting different temperatures) only at the beginning of the hour or 30 minutes after the hour.
The AC was used in POWER mode for a longer duration than in REGULAR mode during this 3-hour period.
1. Question:
How many times the AC must have been turned off between 11:01 pm and 1:59 am?

DILR questions in CAT test your ability to interpret data and apply logical reasoning to solve problems. These questions often involve tables, graphs, puzzles, and arrangements. Focus on identifying easy sets, and managing time efficiently to build accuracy and speed.
1. Carefully analyse the data presented in charts or tables before attempting questions.
Before diving into calculations, take a moment to examine the data provided thoroughly. Understand the type of chart (bar, pie, line graph, table, etc.) and what information it conveys. Identify units, periods, categories, and any trends visible. This initial overview helps prevent mistakes and ensures you interpret the data correctly.
2. Identify key trends, ratios, and percentages to simplify calculations.
Spotting important patterns, ratios, or percentage changes in the data can simplify complex problems. Instead of solving every detail, focus on key relationships between data points. For example, calculating percentage increases or decreases or finding ratios between categories often leads to quicker solutions.
3. Use approximation to save time without compromising accuracy.
Data Interpretation questions often allow for rounding off numbers to save time. Use approximations where precise calculations are not required, especially with large or complex figures. This strategy speeds up solving while maintaining sufficient accuracy to choose the correct option. However, avoid over-approximating, which can lead to errors. Regular practice will help develop a sense of when and how much to approximate effectively.
4. Break complex data sets into smaller, manageable parts.
When faced with large or complicated data tables, divide the information into smaller sections. Focus on one segment at a time instead of trying to analyse everything simultaneously. This reduces cognitive overload and helps in better understanding. Answer questions related to each segment before combining insights to solve bigger problems.
5. Avoid unnecessary calculations by focusing on relevant information.
Many DI questions contain extra data that isn’t needed to answer the specific query. Identify and ignore irrelevant information to save time. Carefully read the question to understand what exactly is being asked. This prevents wasting effort on needless calculations.
6. Practice regularly with diverse DI sets to improve speed and accuracy.
Consistent practice is essential to mastering DI questions. Work on various question types, including tables, graphs, charts, and caselets. Exposure to different data formats builds familiarity and enhances your ability to interpret data quickly. Regular practice also helps in developing shortcuts, spotting patterns, and reducing calculation errors.
Read on to know about the major tips to solve CAT Logical Reasoning Questions:
1. Read the entire set carefully before attempting questions
Start by thoroughly reading the complete question set. Understand the scenario, constraints, and what is being asked before jumping into answers. This ensures you don’t miss any vital details. Logical Reasoning questions often contain hidden conditions or subtle clues, so reading carefully helps in setting a solid foundation for solving. Avoid assumptions not supported by the given data to maintain accuracy and logical consistency throughout.
2. Organise the data using diagrams or tables
Converting textual information into structured formats like tables, matrices, or diagrams makes it easier to visualise relationships and constraints. Logical puzzles, seating arrangements, or grouping problems become more manageable when you sketch the scenario. This visual approach helps track fixed and variable positions, reduces confusion, and speeds up the solving process. A neat structure also reduces errors and makes it easier to revisit the logic if needed.
3. Start with the definite information first
Always begin solving with the most concrete, fixed pieces of data. Establishing the known facts first helps in narrowing down possibilities for the unknowns. Once you place the definite elements, it becomes easier to apply conditions and make logical deductions. Trying to start with assumptions or unclear clues leads to confusion.
4. Eliminate impossible scenarios through logic
Use the process of elimination to discard options or arrangements that violate given conditions. Logical Reasoning is often about narrowing down choices using constraints rather than solving linearly. Carefully testing each option against all rules and eliminating inconsistent ones helps you arrive at the correct answer faster. This technique also minimises time spent on trial and error and boosts accuracy, especially in complex LR sets with multiple variables.
5. Avoid spending too much time on one set
Time management is key in CAT. If a Logical Reasoning set seems too complex or time-consuming, move on and return later if time allows. Getting stuck on one set can affect your chances of attempting other easier questions. Prioritise solvable sets and maximise your score through smart selection. Practising CAT mock tests will help build the judgment to decide when to move on or stay with a set.
6. Practice consistently with past CAT LR questions
The best way to master Logical Reasoning is consistent practice using past CAT papers and mocks. This helps in understanding the pattern and difficulty level of CAT LR questions. Regular exposure to different types of reasoning problems, arrangements, groupings, and puzzles. It also builds speed, logic, and accuracy. Review your solutions after each practice to understand mistakes and improve. Over time, this habit strengthens your approach and boosts confidence during the actual exam.
Preparing for the DILR section in CAT 2025 requires a smart and focused approach. This section tests analytical thinking and decision-making under pressure. Here are the major preparation tips for CAT DILR 2025:
Start by gaining complete clarity on the CAT DILR exam pattern and syllabus. The section typically includes four sets with 5–6 questions each, covering topics like bar graphs, pie charts, seating arrangements, puzzles, and caselets. Knowing what to expect helps you prioritise topics and tailor your preparation accordingly.
Before attempting advanced-level questions, ensure you are comfortable with basic data interpretation and logical reasoning concepts. Learn to identify patterns, understand relationships, and calculate quickly. Solid foundational skills will help you approach complex sets with better confidence and minimise errors during the exam.
Regularly attempt sectional tests with a strict timer to simulate the exam environment. Focus on accuracy and speed while solving. Reviewing your performance after each test helps you identify weak areas and adjust your strategy. Over time, this improves your ability to handle pressure and manage time effectively.
Studying previous year's CAT DILR questions is one of the best ways to understand the difficulty level and question patterns. Practice sets from the last 5–7 years to recognise recurring types of problems. This helps develop familiarity and better question selection strategies during the actual exam.
Not all DILR sets are of equal difficulty. Learn to quickly scan all sets at the beginning of the section and identify the easiest ones first. Prioritising easy questions boosts confidence and saves time. Avoid spending too long on one set, and move on if stuck.

Hello Sahitya
For FMS Delhi, your percentile should be 99%+ and it should be 99.5%+ to be on the safer side.
Now coming to the academics:
1. 10th marks: 75%+ are given 10 out of 10
2. 12th marks: 75%+ are given 10 out of 10
3. Graduation marks: FMS doesn't considers graduation marks for screening.
So if you have 75%+ in both 10th and 12th, you will get full marks in academic score.

Hello Ayush
This is definitely a myth that with 0 work-ex you can't get IIM ABC because freshers still get into them although the competition is brutal but if you have good academics (9/9/9) and a good CAT (99.5%+), you have a chance.
These are some other good colleges except IIM ABC which you can aim for:

Hello Aspirant,
With an AIR (All India Rank) of 1,60,000 in NEET and in the OC (Open Category) there is a very slim chance of getting an MBBS seat in a government medical college, especially in General Category seats through All India Quota (AIQ), but here are some options:
You can also participate in state counselling rounds, as sometimes, seats remain vacant/unfilled, including mop-up rounds.

Hello Anshuman!!!
You have gotten 86% in 10th, which is a good score. 70% in graduation is not the best but decent. But the main problem is your 12th score which is 62%.
You would be already aware that the Top IIMs (BLACKI) give a big emphasis on your academic score. Let me tell you one example of IIM Ahmedabad,
According to a research i read a few days ago, in IIM Ahmedabad,
70.8%
of students has 90+ percent in 12th,
25.8%
has 80-90 percent and around
3.8%
has less than 80% with the bracket of 60-69 having only
0.26%
students of the total batch. Nearly same is the case of the other top IIMs like IIM Bangalore, IIM Calcutta, IIM Lucknow, IIM Kozhikode and IIM Indore.
Statistically, getting into these TOP IIMs is possible with 62% in 12th is possible (0.26% has done it) but practically you cannot get into these TOP IIMs unless you top the CAT exam.
See, I don't wish to dishearten or demotivate you but I wish to tell you the truth. Although the probability of you getting into these TOP IIMs is very less, but trying is better than doing nothing. You have a good score in 10th which will certainly help you. The least you could do is try your best.
My advice would be that you should not focus on these things like "Will I get top IIM" or negative talk like " I got low marks I won't qualify" etc.
The main focus should be on your preparation.
Give 100% in your preparation because that's the only thing in your hand. You can't change your 10th/12th/Graduation scores but you can put some more effort in your preparation which would certainly help to get better percentile.
Keep working hard and give your best. You might surprise yourself!!! And if not BLACKI, there are many other good colleges like FMS, MDI, newer IIMs etc.
