## Geometry and Mensuration - Important Concepts & Formulas

Geometry is one of the main areas of Mathematics. Basically it is a study of shapes. The word 'Geo' means 'Earth' and 'Metry' means 'Measure'. So Geo - metry is literally 'Measurement of earth'. Traditional geometrical concepts are called Euclidian Geometry (mainly in two-dimension). Geometry is a sure area in all Placement Test & B-School entrance exams. In this article, you can learn Important Concepts & Formulas of Geometry and Mensuration along with the examples

## Functions and Graphs

In the new pattern of all B-school entrance exams, different exam boards giving an importance in this area. An average of 4 to 5 questions in almost all the top level exams (CAT,XAT etc)can expect from this chapter. XAT contains a large number of questions related to the user defined functions than the pure mathematical functions. A clear theoretical awareness of the concept of functions is required to solve most of the questions.

## SI & CI - Forumulas, Concepts & Tricks

SI & CI is basically a continuation of the application of percentage calculations. A well understanding and a rigorous practice will make you able to tackle the SI & CI questions easily and interestingly. Questions from SI and CI is common in most placement tests, bank PO, MAT,CAT and XAT competitive exams. This article provides important formulas, concepts, tips and tricks to solve aptitude questions on SI & CI.

## Simple Equations - Concepts & Tricks

All placement test and competitive exams consist directly or indirectly test your basic skills in the area of algebra through simple equations. Here we explain various concepts of simple equations along with the ways to solve them using examples.

## Special Equations

So far we have discussed about simultaneous linear equations in many variables. In this special module we are going to consider the extended properties of simple equations, which is generally called 'Special Equations'.
