No other question in the CAT is as deceptively simple as Paragraph Completion questions. Superficially, they do not require us to know or remember any rules. They, in fact, require us to do something far more difficult â€“ to think like the writer.
Since the last weekâ€™s post on Parajumbles, I have been thinking hard over an appropriate parallel to explain the process of solvingÂ Paragraph Completion question. And all my thoughts end once again at the same point â€“ Sherlock Holmes. Indeed, picking up the scattered clues, and building them into a clear chain of reasoning for anticipati

Whenever someone starts a new business, some money is needed to start the business. This initial investment is called the CAPITAL. In large companies & enterprises, it is very much possible that there could be more than one person investing the money. These could be either partners or shareholders. Both mean the same thing except for the liability they have for the business. It is easier for a shareholder to quit the business, by selling his SHARES in the stock exchange, whereas a partner cannot leave just like that.
So, what is a Share? In simple terms, it is a certificate issued b

Descartesâ€™ rule of signs is used to get information on the number of real zeros of a polynomial. This is useful in the cases where the graph is not provided for a polynomial.
You need to know that for equations with real coefficients, complex roots occur in pairs. As a result, any equation with an odd degree must have at least 1 real root. This combined with Descartes rule generates some interesting insights, as we will discuss in following examples.
Let us understand the rule with an example:
f (x) = x5 â€“ 3x4 + 3x3 + 5x2 â€“ x + 5
This rule doesnâ€™t help us actually find the

UNDERSTANDING BASE SYSTEMS:
The numbers that we commonly use are the decimal number. The system is called the decimal system. Why is it called the decimal system ? It is because it has 10 symbols - 0 , 1 , 2 , 3 , 4 , 5 ,6 , 7 , 8 , 9 .
For example : 85 means - 8 * 10^1 + 5 * 10^0
Here , 10 is known as the base of the decimal system.
In this article , we will learn about other bases , how to express various numbers in such bases and questions according to CAT , XAT and OMETs.
BASE : Â It is the number of distinct symbols used in a particular number system.
For example
So, depending o

Questions based on Punctuation marks have been asked in competitive exams frequently. These concepts are really important if you are looking at some of the banking exams or exams like SNAP. It is a good way to check a person's 'Verbal Ability'. With the help of my friend Sanket, I have a compiled a set of some examples followed by some previous year questions that can help you understand the concept better.
The Purpose of Punctuation:
Punctuation is used to disambiguate a sentence by using spacing, conventional signs, and certain typographical devices
Punctuation introduces appropriate paus

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
We know that a number N can be written as a product of its factors as given below
Â N = ap x bq x cr â€¦
Here a,b,câ€¦ are prime factors of N
& p,q,r â€¦ are the powers of the prime factors of N.
In such a case the number of factors of N are given by the formula

What are Logical Connectives?
Logical connectives are basically words or symbols which are used to form a complex sentence from two simple sentences by connecting them. Some Logical Connectives are â€“ If, Only if, When, Whenever, Unless etc. Questions based on statements formed using logical connectives are simpler than other questions of exam so it will be beneficial to take command on this topic.
These type of sentences consist of two parts, one is Cause and one is Effect. Usually Cause is present after the connectives.
Some examples are like-
1. If you are in navy, you have to wear u

The concept of â€˜divide and conquerâ€™, derived from the Latin phrase â€˜Divide et imperaâ€™, 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 â€“ he wasnâ€™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 â€˜nâ€™ digits of the number. If

Data Interpretation section of CAT revolves around decoding the structured data and deriving meaningful results from the given data. Its significance cannot be undermined in todayâ€™s world as strategies are planned and implemented on the basis of inferences and results determined through this vast amount of data. Thus, this topic holds an inevitable place in CAT exam and around 16 questions are asked from it. The data can be represented in form of lines, graphs or charts, tables, and caselets etc. And, in this blog, we will be talking about one special kind of graph known as bar graphs. B

Data Interpretation holds an inevitable place in todayâ€™s world. Everything revolves around the data. Itâ€™s being continuously collected, structured and then meaningful conclusions are drawn from it after careful research and analysis. Thus, data is important but itâ€™s useless without its accurate interpretation and thatâ€™s why Data interpretation is included as a section in various competitive exams especially MBA entrance exams such as CAT, XAT, IIFT, SNAP etc. In these exams, data will be represented in various formats such as graphs, charts, tables etc. along with 3-4 questions tha
