Introduction to Quantitative Aptitude | Learn Quantitative Aptitude

Hello Aspirants,

Quantitative Aptitude is the most important part for clearing any competitive examination. This section is asked almost in every competitive examination. It simply, is a test of caliber of an aspirant's mental ability as how a particular aspirant responds to certain problems and mindset of the aspirant to tackle them. The evaluator evaluates analytical skills and capability of playing with numbers and thinking power of an aspirant. 

As everybody has studied Mathematics at least up to Matriculation, hence here we will study the basic concepts of Aptitude which will give base to our preparation. Later on we will learn the tricks to speed up the calculations and various approaches to solve typical problems. 

In short, we will study 

1) Basics of Aptitude

2) Tricks to speed Up Calculations and

3) Developing a skill to solve problems by

     i) Traditional Method 
    ii) Short Trick Method.

Let us take a look at the Syllabus Of Quantitative Aptitude !

Quantitative Aptitude Syllabus can be divided as Follows :

A] Simplification / Approximation

B] Number Series

C] Quadratic Equation 

D] Data Interpretation

E] Arithmetic Word Problems

Now, We will discuss it one by one completely.

A] Simplification / Approximation - 

Simplification / Approximation is the highest scoring portion in the competitive examinations. It consists of basic numeric calculations such as addition, substraction, multiplication and division with basic rules of VBODMAS.

"Simplification means not actually solving the problem but solving by making it in a Simpler Form." 

B] Number Series -

"A Number Series is a sequence of numbers arranged with a logic."

Numbers in a Series are known as 'Terms' which follow a certain definite pattern. We have to identify the logic associated with the series and answer accordingly. Generally, Number Series can be categorized as follows :

 Missing Number Series

 Wrong  Number Series 

C] Quadratic Equations -

"Quadratic Equation is an equation in which the highest Degree or Power of variable is '2'."

In this type of questions there are two quadratic equations are given. One in the form of variable 'x' and another in terms of variable 'y' and we are asked to find and establish a relationship between them.

The values which satisfy a Quadratic Equation is termed as 'Zeros' or 'Roots' of a Quadratic Equation.

D] Data Interpretation -

Data Interpretation refers to assessment of collected data or information with a motive to utilise the results for gaining useful information. Various conclsions can be drawn from the given data.

Types of DI asked- 

• Caselet DI
