The Common Admission Test (CAT) is a very competitive test for admission to top management institutes such as the IIMs. To assist aspirants in making their preparation stronger, we present to you a systematic 60-day series on key topics. On Day 9, we will deal with Profit & Loss questions, an important section of Quantitative Aptitude, and Logical Reasoning & Data Interpretation (LR & DI).
This article gives a combination of concepts, solved examples, and problem-solving techniques to enable you to excel in these sections. There are a range of profit and loss problems with step-by-step solutions, along with LR & DI practice sets to enhance speed and accuracy. By going through this article, you will have improved conceptual understanding and confidence in solving these questions under the time limit of the CAT 2025 exam.
Today, we are here with the extended part of the percentage, i.e., Profit and Loss. The Percentage is the basic building block of Arithmetic. Profit and Loss CAT questions are one of the most important topics for the CAT Exam. To solve the CAT Profit and Loss questions, you must first understand the basics of Profit and Loss. We can understand the basics well with the help of the profit triangle, as shown below:

The price at which we purchase something is the "cost price" (CP).
The price that we mark or print on the article is the marked price (MP).
The price at which we sell something is its selling price (SP).
Marked Up % = (MP-CP) x100/CP
Discount % = (MP-SP) x100/MP
Profit % = (SP-CP) x100/CP
If SP is less than CP, then profit is loss.
CAT Profit And ’Profit and Loss Type:
Questions involve direct calculation to find profit%, Discount% or Markup%.
Questions in which values are given in terms of profit%, Discount% or Markup%.
Any two of these are given, and the third one is asked.
Questions on successive discounts.
Questions on actual weight and faulty weights.
Questions based on adulteration.
Questions based on basic formulas only, and many more.
You have to prepare each type of Arithmetic question separately for a better understanding of the concept.
The two previous year CAT questions on Profit and Loss are given below for a better understanding. The arithmetic section caries one of the greatest weightage in CAT arithmetic questions:
Q1. If a seller gives a discount of 15% on the retail price, she still makes a profit of 2%. Which of the following ensures that she makes a profit of 20%?[CAT Question Paper 2017 Slot 1]
Give a discount of 5% on the retail price
Give a discount of 2% on the retail price.
Increase the retail price by 2%.
Sell at retail price
Ans: D
15 % discount means If MP = 100; SP = 85
2 % profit means If CP = 100; SP = 102
In both SP should be same, so make them equal and we get
SP= 510, CP= 500 and MP = 600.
For 20% profit SP =600 which is equal to MP (Retail Price).
Q2. On selling a pen at 5% loss and a book at 15% gain, Karim gains Rs. 7. If he sells the pen at 5% gain and the book at 10% gain, he gains Rs. 13. What is the cost price of the book in Rupees? [CAT Question Paper 2019, Slot 1]
85
95
80
100
Ans: (3)
Let CP of pen = 100x; CP of book = 100y
Case 1
-5x + 15y = 7
Case 2
5x + 10y = 13
On solving both equations y = 4/5
CP of a book = 100x(4/5) = Rs 80
Prerequisite Before Practising CAT Profit and Loss Questions :
To prepare this topic for the CAT exam, students must have knowledge of
Fractions
Approximation
Learning conversions from Application of Percentage to fractions is important for this topic also.
Practice questions based on Application of Percentage well.
You can use the following tricks to solve the particular type of question:
If two articles were sold at an equal price with a profit of a% on one article while a loss of a% on another. Then, there will always be a loss of $a^2$/100 %.
If n articles were purchased at equal prices and sold at different prices. Then, net profit % is the average of all profit %. Loss % will be treated as negative of profit %.
In the questions of true weight/ false weight, the Selling Price has always been calculated on the reading while the Cost price has always been calculated on actual weight. After that compare the final selling price and final cost price to find profit or loss percent.
In the questions of successive discounts, use the concept of the successive percentage change.

CAT previous year papers
Previously, we have discussed general types of data interpretation. In this article, we are going to discuss the miscellaneous types of data interpretations for the CAT exam, like
Multi-Layered Pie Chart
Double Bar Graphs
Logic Based DI (most common in recent years)
Combination of two or more types of graphs in a single DI
i.e. table with a pie chart, line graph with bar graph, etc.
Such graphs are used to represent more data on a single graph.
In the CAT Exam and other management entrance exams, data interpretation is a must-come topic.
Understanding Charts and Graphs
Understanding the logic or concept (More required in multi-layered DI and Caselet DI)
Be good at calculations.
The multi-layered pie-chart below shows the sales of LED television sets for a big retail electronics outlet during 2016 and 2017. The outer layer shows the monthly sales during this period, with each label showing the month followed by the sales figure of that month. For some months, the sales figures are not given in the chart. The middle-layer shows quarter-wise aggregate sales figures (in some cases, aggregate quarter-wise sales numbers are not given next to the quarter). The innermost layer shows annual sales. It is known that the sales figures during the three months of the second quarter (April, May, June) of 2016 form an arithmetic progression, as do the three monthly sales figures in the fourth quarter (October, November, December) of that year. [CAT Question Paper 2018]
Q1. What is the percentage increase in sales in December 2017 as compared to the sales in December 2016?
22.22
38.46
50.00
28.57
Solution: (4)
Sales in December 2017 = (500 – 150 -170) = 180
Sales in Q4 of 2016 is in AP:
Sales in October 2016 = 100; Sales in November 2016 = 100 + x; Sales in December 2016 = 100 +2x;
So, 100 + 100 + x + 100 + 2x = 360
X = 20
Sales in December 2016 = 100 +2x20 = 140
Increase in sales in December 2017 as compared to december 2016 = 40x100/140 = 28.56%
Q2. In which quarter of 2017 was the percentage increase in sales from the same quarter of 2016 the highest?
Q1
Q3
Q2
Q4
Ans: (1)
2016 | 2017 | %age increase | |
Q1 | 240 | 380 | 140*100/240 = 58.33% |
Q2 | 150 | 200 | 33.33% |
Q3 | 250 | 220 | -12% |
Q4 | 360 (calculated in Question 1) | 500 | 46.66% |
Prerequisite:
To prepare for data interpretation for the CAT exam, a student must have an understanding of
Average, ratios and percentages at fingertips
Pie graph, table graph, and other forms of data interpretation
Venn diagram
Read the graphs carefully.
Interpret the data from each kind of graph separately and then use them.
Solve small calculations mentally.
Examine each question separately and solve the easy one first.
Practice questions that involve more than 2 graphs in a single DI.

Optimally, you should begin prepping at least 9-12 months beforehand the examination. There should be plenty of time during this period to establish solid foundations, practice mocks, and finalize your strategy.
CAT's unpredictable level of difficulty is known to everyone, but it also usually stays demanding with time limitation and stiff competition. With good preparation, firm concepts, and test-taking strategy, you are capable of mastering it effectively.
Yes, it is possible to prepare for CAT in 9 months. For effective preparation, follow our 60-day CAT preparation series in which we cover all the topics required for CAT.
Getting 99 percentile in three months is achievable but needs rigorous preparation, daily mock tests, and clear conceptual understanding. Candidates with experience in aptitude tests or very good problem-solving skills have a higher chance.
Three months might be enough if you are already well-versed in Quant, Verbal, and Logical Reasoning. But beginners might find it difficult to go through the entire syllabus and take enough mock tests within a short period of 3 months.

Hello dear,
The CAT exam requires a significant amount of time for preparation, including brushing up on basic concepts and practicing advanced problem-solving. Starting too early can feel overwhelming and may not be sustainable with other academic commitments.
The CAT exam requires a level of focus and maturity that is not always present in class 9. Starting preparation at this stage can be challenging to maintain. At class 9, you're primarily focused on learning foundational concepts. So you just need to boost your fundamentals by practicing more and more at class 9 because the Quantitative Aptitude section of CAT syllabus includes all the topics of Mathematics from Class 9 to 10 such as Arithmetic, Geometry, Algebra, Trigonometry and Mensuration.
Start Preparation 12 Months Prior:
