Highest, Longest, Tallest, Largest, Smallest places form an important part of questions in competitive examinations like XAT, IIFT, IBPS, TISS, Bank PO etc. Below is a list of some of the most important Longest, Largest, Highest places around the World and in India.
This post has been divided into two sections, Around the World and Inside India.
In the first section, Around the World, all the places have been divided into sub-sections based on Longest, Largest, Highest, Tallest, Smallest and Biggest.
In the second section, Inside India, all the places have been divided into sub-sections

I got a lot of feedback via emails and texts that people are looking for a post on geometry. I have been avoiding it for sometime because of two main reasons:
a) It is not one of my strong areas.
b) It takes a lot of time to draw the diagrams that are sometimes required to explain the fundas.
The questions on geometry are the trickiest and consumes the maximum amount of time as compared to the questions on other topics in Quantitative aptitude that is why, I have compiled a list of fundas that you might find helpful in solving CAT level questions. I am splittin

Questions on clocks (or even calendars) are not really frequent in CAT these days. They used to be really popular few years ago. Having said that, it is always better to understand some of the basic principles and the types of problems that get asked. They might come in handy in case of other exams like CMAT, MAT, SNAP, etc.
Clock problems can be broadly classified in two categories:
a) Problems on angles
b) Problems on incorrect clocks
Problems on angles
Before we actually start solving problems on angles, we need to get couple of basic facts clear:
Sp

Figuring out the last digit is the same as figuring out the remainder of a number when divided by 10, but I guess you already know that. Figuring out the last two digits is the same as figuring out the remainder of a number when divided by 100. However, if you wish to figure the remainder when the divisor is not 10 or 100, I suggest you read on.
Funda 1 of Remainders:
Basic idea of remainders can be used to solve complicated problems.
There is nothing special or unique about this idea. At first glance it seems like something really obvious. But it is it

Quadratic Equations are first taught to us in 6th or 7th class and most of us are able to score good marks in it because we are able to solve 90% of the questions by just using that formula. And that formula is:
The above formula gives us the roots of the quadratic equation ax2 + bx + c = 0
For this post, I am assuming that you are aware of the basics of quadratic equations and know how to use the above mentioned formula. In case you are not, spending five minutes on the wiki page of Quadratic Equations won’t hurt. Wikipedia can be daunting at times, so come back here as soon a

In this Number of trailing Zeros blog post, We would like to cover these two ideas:
Number of trailing zeroes in a Product or Expression
Number of trailing zeroes in a factorial (n!)
But before I begin, let us first try to understand what exactly are ‘trailing zeroes’. It is nothing else but the number of zeroes at the end. I do not want to sound pedantic but on many occasions when you see a question which asks about, “What is the number of zeroes in ___” it is incorrect, because it should actually say – “What is the number of trailing zeroes?” or “What is the

Understanding Percentage
The word “Percent” can be understood as “per 100” or “out of 100”. Percentage in itself is a dimensionless number used to tell how many parts per hundred are being considered. It is often denoted using the percent sign, "%". The reference point for calculating percentage is taken as 100.
If in a class of 100 students, 90 students passed in a subject then the percentage of students who passed in the exam is 90%. Had the total number of students been 200, the percentage would have reduced to 45%. This is because 45 students out of every 100 students pas

In this post, we will learn how to solve Logical Reasoning Problems based on coins and matchsticks picking puzzles. To understand how exactly these kinds of puzzles look like, let’s start the post with a very simple example. The method to solve the example will give better insight so as to how to approach these puzzles.
Two smart players A and B are playing a coin game in which they can pick up 1, 2, 3 or 4 coins. They have 78 coins and the player who picks the last coin will lose the game. A and B play alternately and A plays the first move. How many coins should A pick at first so h

In a series of posts, we are going to cover the basics of some DI/LR topics. The first topic of discussion is Binary Logic. In a binary logic problem, we have people who either speak a true statement or a false statement. These people are divided into three categories:
Truth-teller: This person will always speak the truth. All the statements made by this person are true.
Liar: This person will always tell a lie. All statements made by this person are false.
Alternator: This person always alternates between the truth and the lie. If first statement of this person is true, then se

Data Interpretation questions typically have large amount of data given in the form of tables, pie charts, line graphs or some non-conventional format. The questions are calculation heavy and typically test your approximation abilities. A very large number of these questions check your ability to compare or calculate fractions and percentages. If you sit down to actually calculate the answer, you would end up spending more time than required and most of us can't afford to lose precious time during competitive exams like CAT, XAT, IIFT etc. Here are few ideas that you can use for approxim
