Sentence rearrangement or Jumbled paragraph questions have been a regular feature in the Verbal Ability section of the CAT. In this question type 4-5 sentences are given in a random order without any indication of the introductory or the concluding sentences. The sentences, when logically reorganized, form a coherent paragraph.
This question type can be quite difficult since the subject matter and the sentences in which they are contained are often dense and complex. At times, the sentences can be lengthy and the theme esoteric or scholarly – something an average CAT aspirant is not v

let me first list down the topics that I am going to cover in this particular blogpost:
Number of factors of a given number
Number of even factors or odd factors of a given number
Sum of all factors of a given number
Sum of all even factors or odd factors of a given number

N = ap x bq x cr …
Here a,b,c… are prime factors of N
& p,q,r … are the powers of the prime factors of N.
In such a case the number of factors of N are given by the formula

The concept of ‘divide and conquer’, derived from the Latin phrase ‘Divide et impera’, was put into use effectively by everyone from Caesar to Napoleon to The British in India. Even Gaddafi tried using the same but as current events show us – he wasn’t very effective. Dividing rather divisibility rules to be specific can come in really handy at times in solving problems based on Number Systems.
The standard rules which nearly all of us are very comfortable with are the ones for 2n and 5n. For these all that one needs to do is look at the last ‘n’ digits of the number. If

On the official CAT website, a media release was put out last night highlighting some of the changes for the CAT 2020 exam. Since then, I have gotten a couple of emails, a few phone calls, and a lot of whatsapp messages about it. I thought it would be a good idea to pen down my thoughts about the same and hopefully, calm down a few CAT aspirants who are panicked, unnecessarily in my opinion.
What are the changes in CAT 2020?
The deadline has been extended to 5 PM of 23rd September
CAT 2020 will be conducted in 3 sessions (unlike 2 last year)
CAT 2020 will be a 2 hour exam (unli

During CAT prep while training for Reading Comprehension you will often come across many different types of questions. One such question type we shall classify as the EXCEPT question. In this question type the question stem might contain qualifiers like “EXCEPT,” “LEAST,” or “NOT” in them.
For example, let us say the question asks, “All of the following are true EXCEPT…”
If you are not careful and If you give them an answer that IS TRUE, it is wrong!
The question is really looking for what is NOT true.
Be careful to note these qualifiers or you may identify th

In one of the earlier posts on this blog, we had discussed the important books for CAT preparation and how reading helps with tackling the verbal ability section. If you go through a lot of the reading comprehension passages asked in exams you will realize they are similar in tone to these books or newspaper articles and that is why reading helps.
But just reading will not help. To really shave off time required in answering a question (especially in RCs) it is best if you know what the words mean eliminating the need to guess or take time to understand what the passage is talking about

Quantitative Aptitude is an important part of the CAT exam. If you look at the pattern of the paper for the last few years, it has had a weightage of roughly 1/3rd since CAT went online in 2008. From 2015, Quant has had 34 questions out of 100. The same pattern is expected to continue in 2020 as well.
Broadly speaking, Quantitative Aptitude can be further divided into 5 sub sections:
Arithmetic
Algebra
Geometry
Number System
Modern Maths
While the exact number of questions in these topics changes every year there are some broad patterns that can be noticed. We lo

Quadratic Equations based on x + 1/x:
x + 1/x is itself a category of questions. There are many variants of this in which either you were given a value of this equation or you have to find the higher degree value which would be similar to this equation.
For a clear understanding let’s do some examples:
Example 1: If 6(x2 + 1/x2) - 5(x + 1/x) = 38 and x is positive and rational then find the value of x.
Sol: In this question, firstly we have to make the first bracket as a complete square of the second bracket. This we can by adding 2.x.1/x which is equivalent to 2. Then the equat

In the quadratic equations word problems, the equations wouldn’t be given directly, in fact, you have to deduct the equation from the given facts within the equations. There could be many different traits of question which can even include all the linear equations type questions into the quadratic form. It can also include profit maximization or loss minimization questions in which you have to find either minimum or maximum value of the equation.
Here are a few examples of the word problems in quadratic equations:
Example 1: Four friends have some coins. Pavan has 2 less than Samir,
