Hello CAT 2024 aspirants,

The CAT exam for MBA admission in 2024-2026 is scheduled for November 26. In this 60-day CAT preparation guide series by Careers360, we’ll be discussing the strategies for Day 21 to help you prepare effectively and excel in the CAT entrance test 2024.
This article will cover CAT questions on logarithms, modulus, and circular arrangements, as well as VARC questions. Logarithm and modulus problems can be quite challenging, and students sometimes struggle with them. Various difficult logarithm problems can be found online, and it's essential to engage in thorough practice sessions. Additionally, reviewing previous years' logarithm questions can be beneficial for your preparation.
Logarithm is an important part of algebra and is consistently asked in the CAT entrance exam. We will also cover a few Logarithm CAT questions and modulus. Students can also refer to the logarithm questions for the CAT pdf as well for more practice.
In the simplest terms, what a logarithm is:
If ax = N, then x = loga N.
Here ‘a’ is the base of the logarithm.
For Example:
102 = 100; So, 2 = log10100
A modulus is a function which always returns a positive value. The graph of the modulus function is symmetric about the y-axis.
For Example:
If |x| =2, then x can be 2 or -2.
(a part of CAT Arithmetic questions) Learn all the properties related to Logarithm.
The following are some of the key characteristics of logarithms:
loga xy=loga x + loga y
loga x/y=loga x - loga y
logaxn = nloga x
logan xm =m/n logax
logax = 1/ logxa (Base Change Operation)
logaa= 1
loga1 = 0
a^(logax) = x
loga (x+ y) ≠ loga x + loga y.
loga xy ≠ (logax) (logay)
The logarithm to base 1 is not defined.
Questions of modulus can be solved by squaring both sides
For example:
If x =y, then x2 = y2 and we can solve accordingly.
Practice inequality problems based on logarithms.
Candidates preparing for the CAT should dedicate time to practice a wide range of inequality questions to ensure they're well-prepared for any variation that may appear on the exam.
The characteristic of a number is defined as
If log N = 4.73, then the characteristic of N is 4 and Mantissa is .73.
This property is used to find the number of digits in a given number.
i.e. Number of digits = characteristics + 1.
For example: find the number of digits in 212
log 212 = 12 log 2 = 12 x 0.3010 = 3.612
Therefore, the number of digits in 212 will be (3+1 = 4)
Logarithms are used to solve exponential equations and hence can be used for analysis while designing software or hardware.
The modulus Function gives magnitude only irrespective of the direction of the variable.
In the CAT exam, 1-2 questions are expected from this function.
Q1. For a real number a, if (log15a+log32a)/[(log15a) (log32a)] = 4 then a must lie in the range [CAT 2021, slot-3]
4 < a < 5
3 < a < 4
a > 5
2 < a < 3
Solution: (1)
(log15a + log32a)/[(log15a) (log32a)] = 4
⇒ 1/ log32a + 1/log15a = 4
⇒ loga 32 + loga15 = 4 (Using base change property)
⇒ loga(32x15) = 4
⇒ a4 = 32 x 15 = 480
Doing hit and trial;
24 = 16
34 = 81
44 = 256
54 = 625; clearly a4 lies between 256 and 625.
So, a must lie between 4 and 5.
Q.2
equals ____________ [TITA, CAT 2020]
Solution:
Find the value of the denominator first as follows:
(log2 4)2 = 4
Using properties of logarithm
log4 8 = log28/ log24 = 3/2
So, (Log48)3 = (3/2)3 = 27/8
Similarly,
log816 = log216/ log2 8 = 4/3
So, (Log816)4 = 256/81
Therefore, denominator becomes 4 x (27/8) x (256/81) = 128/3
So,
= (2x 4 x 8 x 16)/(128/3) = 24
Hence, the correct answer is 24.

Previous Year's Question Papers
Directions: Study the following information carefully and answer the questions given below:
Bhuvan, Mohan, Kartik, Hina, Tina, Ramu, David, and Aastha are sitting around a circle facing the centre. Ramu is third to the right of Bhuvan. Hina is second to the right of Aastha who is second to the right of Ramu. Karthik is third to the right of Tina who is not an immediate neighbour of Hina. David is second to the left of Tina.
Q1: Who is to the immediate left of Mohan?
Ramu
Tina
Bhuvan
Kartik
Q2: Who is the third to the left of Bhuvan?
Bhuvan
Aastha
Kartik
Tina
Q3: Who is the third to the left of Hina?
Astha
Tina
Kartik
Ramu
Solution: From the given information, we can make the following figure.
Tricks: Use the Initials of the name while drawing diagrams.
Draw all possibility diagrams.
Ans 1: (d)
Ans 2: (b)
Ans 3: (b)
Direction: Study the following information to answer the given questions:
Asha, Binay, Chintu, Daman, Esha, Fatima, Gurmeet and Haresh are sitting around a circular table facing away from the centre where half of them are males and half are females. No two males or two females are immediate neighbours of each other.
Asha is the wife of Haresh. Asha sits third to the left of Esha. Binay sits second to the right of Daman. Daman is not an immediate neighbour of Asha or Esha. Haresh and Chintu are immediate neighbours of each other. Binay is not an immediate neighbour of his wife Fatima.
Q4: Which of the following is true about Gurmeet?
Gurmeet is a male
Gurmeet sits exactly between Fatima and Haresh
Gurmeet sits third to the left of Esha
None is true
Q5: Who sits third to the left of Binay?
Fatima
Haresh
Daman
Asha
Q6: How many people sit between Binay and Fatima when counted in an anti-clockwise direction from Binay?
One
Two
Three
Four
More than four
Solution:
Trick: Notice the important points first
Half are males and Half are females. No two males and no two females are together.
Do not consider a person male or female by their name. Haresh is male (Husband of Asha). Chintu should be female.
All are facing away from the centre:
Left: Anticlockwise
Right: Clockwise
Since Binay sits second to the right of Daman, Daman must be male as Binay is male.
So, male members are Haresh, Binay, Daman, and Esha
And female members are Asha, Fatima, Gurmeet, and Chintu
Since Daman cannot be a neighbour of Esha or Asha, Daman is at position 7, and Binay must be at 5. Haresh will be at 3. So, Chintu will be at 2 and Fatima should be at 8.
Gurmeet will be at 6.
The arrangement will look like
Ans 4: (d)
Ans 5: (a)
Ans 6: (b)
Direction: Study the following information carefully and answer the questions given below:

Previous Years CAT Question Papers
The Cloze test is a combination of fill-in-the-blank and reading comprehension. In this exercise, incomplete words must be filled in using the available options.
A cloze test can be based on the following:
Parts of Speech
Tenses
Articles
Prepositions etc
Read the passage in the CAT question paper thoroughly to get an idea about the flow of the passage.
Write down the key points as you read slowly.
Connect (link) the next sentence with the previous sentence. Reading articles, novels, or newspapers can help with this. Thus, cultivate a reading habit.
Look at the options to get the best word to fit in and eliminate the most unfit word first.
Check for grammatical mistakes, missing articles or prepositions, and other errors.
Attempt CAT mock tests.
VARC CAT questions
You can better understand cloze tests by using the example below.

Hello Amgothu
With 305 marks in ICAR PG and being from ST category, your chances of getting an AIEEA (CAT) seat is good, especially in plant sciences and less competitive subjects
Hello
As you said you by mistakenly done that, you don't need to get worry regarding that ,
Just inform the help desk and carry the correct certifications , the state certificate will not disqualify you .
The steps you can follow is -
1. You can check if the correction window is available or not
2. Contact the CAT desk immediately.
Hope this helps
In CAT registration, you cannot create a new user ID with the same mobile number, even if you use a different email ID. Each mobile number and email can be linked to only one account. If you already registered once, the system will not accept a duplicate with that number. To register again, you must use a new mobile number and new email ID. If you lost your old login, you can recover it through the forgot password/user ID option on the CAT portal.
Yes, you can fill the CAT form even if you currently have a backlog. CAT eligibility requires you to be in your final year of graduation or already graduated backlogs don’t stop you from applying.
While filling the form:
Enter the aggregate percentage/CGPA of marks you have obtained up to the latest semester for which results are declared (in your case till 4th semester).
There will be an option to mention that you have a backlog.
If you clear the backlog later, you’ll just need to show the updated marks during admission.
Hello Aspirant,
Yes, you can apply for the CAT exam as a final-year student. You must declare your backlog on the online application form. You do not write about it on the final-year student certificate; that document is to certify your enrollment status. You must clear all backlogs before the final admission process to any MBA college.
