Number of Trailing Zeros
In this blog post, I would like to cover these two ideas:
Number of trailing zeroes in an expression
Number of trailing zeroes in 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 occassions 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 number of e

Basic Idea of Remainders
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: 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 obvi

Geometry Fundas-1
I got a lot of feedback via comments on my previous posts 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.
With Diwali and CAT approaching I realized that I could not procrastinate anymore because Geometry, as you would agree, is a very important part of CAT-prep. I have compiled a list of fundas that you might find helpful in solving CAT l

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 as yo

Basics of Data Interpretation - Approximation
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. Here are few ideas that you can use for approximation.
Funda 1 – Calculating (Appro

General Awareness - Awards, Medals and Prizes (Part 1)
In philosophy, the study of knowledge is called epistemology, and the philosopher Plato famously defined knowledge as "justified true belief." There is however no single agreed upon definition of knowledge, and there are numerous theories to explain it. When it comes to studying or preparing ‘General Knowledge / Awareness’ for a competitive exam, there are some broad based theories or guidelines which a student can use. I hope you understand that preparing for General Awareness is not an exact science like mathematics and will never b

General Awareness - Awards, Medals and Prizes (Part 2)
In my previous post, we talked about the Nobel Prize, the Booker Prize and the Pulitzer Prize. In this post, I would like to cover other important awards like Bharat Ratna, Padma Awards and Ramon Magsaysay Awards. Although there as hundreds, if not thousands, of people who have won these awards – it is not possible to remember all their names. I have filtered out a few for you. These have a higher probability of being asked.
Ramon Magsaysay Award
The Ramon Magsaysay Award is an annual award established to perpe

Heads of Bodies – National and International
When it comes to MBA entrance exams life CMAT, IIFT, SNAP, etc. the knowledge of the heads of important organizations is really helpful. More often than not, you will end up getting couple of questions on these. There is also a reasonable chance that you will get a question of Match-The-Following type where this information would be really useful.
I have compiled a list of the current heads of important bodies and divided into two parts: India & International. Both of them are given below. (F) indicates that the person is a fema

CLOCKS – FUNDAMENTAL PRINCIPLES
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 proble

We started Handa Ka Funda few years ago by making few amateurish videos and had no idea about what we were trying to do or planning to achieve with it. It felt like something worth doing and we gave it a fair shot. But things have changed since then. Video streaming isn’t a big problem anymore, nearly every student has access to a decent internet connection and people have started caring about issues like audio and video quality. So, in an attempt to keep up with the times, we decided to revamp the website.
We believe that the current model of test preparation of coaching classes is just no
