CAT Exam Part-A: Quantitative Aptitude for CAT 2025
Quantitative Aptitude for CAT 2025 tests your mathematical skills, problem-solving abilities, and numerical accuracy. You have to solve questions on Arithmetic, Algebra, Geometry, and Number Systems to boost your score and improve your overall CAT percentile.
Algebra and Maxima and Minima Questions for the CAT 2025 Exam
Maxima and Minima CAT Questions are used to find the maximum or minimum possible value of a function.
Because the shape of the graph depends on these values.
Example:
In a polynomial function, the maxima is the highest point and the minima is the lowest point and the graph looks like a parabola.
How to find maxima and minima?
Depending on the function, there are several ways to find the maximum and minimum value of a function.
Two main methods are:
Graphical method: In the graphical method, we have to plot the polynomial function on a coordinate plane and visually identify the highest and lowest points on the graph.
Algebraic method: In the algebraic method, we use calculus to find the critical points and then determine whether these points are maxima, minima, or neither.
In maxima minima aptitude questions, the function given can be:
Quadratic function
Linear function
Polynomial function etc.

Admissions Open | Globally Recognized by AACSB (US) & AMBA (UK) | 17.3 LPA Avg. CTC for PGPM 2024
For such functions, we need to find the maximum or minimum values.
We need to study “local Maxima and Minima ”, “maxima and minima formula”, “absolute maxima and minima”, “Maxima and Minima calculator”, and “global maxima and minima” for more details.
Tips To Solve The Maxima and Minima Questions for CAT
Here are some tips and tricks to solve maxima minima aptitude questions:
If the sum of positive numbers is constant then their product is maximum when all numbers are equal. Example: a + b + c = 36, find maximum value of a.b.c The answer is $(36/3)^3 = 1728$

Arithmetic Mean ≥ Geometric Mean $a + b + c = 11$; find Maximum value of $a^3 × b^4 × c^5$ $a + b + c = a/3 + a/3 + a/3 + b/4 + b/4 + b/4 + b/4 + c/5 + c/5 +c/5 + c/5 + c/5 = 11$ Now, AM ≥ GM So, $(a/3 + a/3 + a/3 + b/4 + b/4 + b/4 + b/4 + c/5 + c/5 +c/5 + c/5 + c/5)/12 ≥ (a/3 .a/3 .a/3 .b/4 .b/4 .b/4 .b/4 .c/5 .c/5 .c/5 .c/5 .c/5)^{1/12}$ ⇒ $(11/12)^12 ≥ (a/3)^3 .(b/4)^4 . (c/5)^5$ ⇒ $a^3. b^4. c^5 ≤ 3^3 × 4^4 × 5^5 × (11/12)^12$
Trick: To solve Maxima and Minima Questions, we can use the following trick. Divide 11 in the ratio 3 : 4 : 5 i.e., a = (11/12)3; b = (11/12)4; c = (11/12)5 So, a3. b4. c5 = 33 × 44 × 55 × (11/12)12 (After putting the values of a, b and c)
For a quadratic equation: If the minimum value is to be found, convert the equation in the form of (a – b)2 + k. (Minimum value is k)
Example: find the minimum value of a2 + 26 – 4a a2 + 26 – 4a = (a – 2)2 + 22;
Minimum value is 22
To find the maximum value of a function f(x) can be calculated with the help of a method of derivative. Step 1: find f’(x) i.e., the first derivative.
Step 2: Put f’(x) = 0, and find values of x for which function is either maximum or minimum. Let the values of x be x1 and x2.
Step 3: Find f’’(x) i.e., the second derivative. If f’’(x) > 0 at x = x1 then the function gives minimum value at x = x1. If f’’(x) < 0 at x = x2 then the function gives the minimum value at x = x2. These are local maxima and local minima.
Learn the above concepts well and apply them to solve questions.
Learn basic rules of differentiation.
Use the graphical method to visually identify the maxima and minima.
If the problem involves a specific interval, evaluate the polynomial at the endpoints and compare it with critical points within the interval.
CAT Exam: Maxima Minima Questions for CAT exam From CAT Previous Year Papers
Q1. If three sides of a rectangular park have a total length of 400 ft, then the area of the park is maximum when the length (in ft) of its longer side is:
[CAT Exam 2017]
Solution:
Let one side be a and the other side be b.
So, a + 2b = 400 ⇒ 2b = 400-a ⇒ b = 400-a/2
Area = ab = a (400-a)/2 = (400a – a2)/2
To find maximum value of (400a – a2); differentiate with respect to a
dA/da = 400 – 2a = 0 (For maxima) ⇒ a = 200
So, b = 100
Therefore, the longer side will be 200 ft for maximum area.
Q2. An elevator has a weight limit of 630 kg. It is carrying a group of people of whom the heaviest weighs 57 kg and the lightest weighs 53 kg. What is the maximum possible number of people in the group?
[CAT exam 2017, TITA]
Solution:
Each person must weigh 53 Kg or more.
So, remaining weight = 630 – 53 – 57 = 520
Therefore, no of remaining persons n ≤ 520/53
So, n ≤ 10 (For maximum value n = 9)
Therefore, total persons in the elevator = 9 + 2 = 11
Q3. If a and b are non-negative real numbers such that a + 2b = 6, then the average of the maximum and minimum possible values of (a + b) is:
[CAT 2022 Slot 2]
3
4
3.5
4.5
Solution:
a + 2b = 6
From the above equation, we can say that the maximum value b can take is 3 and the minimum value b can take is 0. a + b + b = 6 a + b = 6 - b a + b is maximum when b is minimum, i.e. b = 0
Maximum value of a + b = 6 - 0 = 6
a + b is minimum when b is maximum, i.e., b = 3
Minimum value of a + b = 6 - 3 = 3
∴ Average = (6 + 3) / 2 = 4.5
Hence, the correct answer is 4.5.
Q4. The minimum possible value of (x2 – 6x + 10) / (3 – x), for x < 3 is:

Q: What are the key differences between linear and circular arrangements?
A:
In circular arrangements, sitting positions are relative and cyclic with no ending point or starting point. In linear arrangements, sitting positions have distinct starting and ending points.
Circular arrangements can be rotated without changing the relative positions of elements, making some configurations equivalent.
In linear arrangements, positions cannot be rotated without changing the relative positions.
Q: How do you handle problems with clockwise and counterclockwise directions?
A:
Clockwise and anticlockwise directions are relative.
Always draw a diagram to visualize better.
Pay close attention to terms like "left," "right," "next to," and "opposite," as they change based on the direction you consider.
Q: What are the best resources for CAT maxima and minima?
A:
Top resources for CAT maxima and minima include Arun Sharma’s Quant book, TMH Quantitative Aptitude, previous year's papers, ebooks, and mock tests focused on application-based problems.

M/s Deloitte Touche Tohmatsu Limited, one of the top four audit and accounting firms in the world with headquarters at London, UK, and with an operational presence in 153 countries, hires Management Trainees (MT) from all the premier management institutes of India thrice every year, in the months of January, May and September.
Each new group of Management Trainees (MT) have to go through a four month rigorous training schedule, after which they have to pass through a test consisting of a written assessment and a case-analysis. The top hundred ranked Management Trainees (MT) based on the performance in the test are confirmed as Management Executives (ME). The rest are given the opportunity of undergoing the training for four months one more time along with the next batch of Management Trainees (MT) and then passing through the subsequent test consisting of the written assessment and case-analysis. The Management Trainee (MT) who fails to get confirmed as a Management Executive (ME) the second time is fired.
The scatter-graph below depicts the number of Management Trainees (MT) at Deloitte taking the tests from January 2020 till May 2022, and the vis-à-vis hired Management Trainees (MT) at Deloitte who were fired :
It is also known that for the month of September 2019 at Deloitte, 96 hired Management Trainees (MT) failed to be confirmed as a Management Executive (ME) the first time, and that 36 hired Management Trainees (MT) were fired.
Question :
In which test did the minimum number of Management Trainees (MT) get confirmed as a Management Executive (ME) in the second attempt ?
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 :
Question:
Assuming that the next customer's order could only be attended to when the previous customer's order was closed, at what time would the first customer's order be considered closed ?

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 :
Question:
A fourth customer comes in and orders two plates of French Toast at 6.24 pm. Suppose Moloy and Niloy had decided to process multiple orders at the same time, however strictly prioritising a first come first serve basis. For exactly how many minutes would one of the friends be idle from 6.00 pm till serving the last customer, assuming that the four customers were the only ones to have come in within the period being discussed ?
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.
