Important topics under Quantitative Aptitude
1. Simplification/ Approximation
These questions require the candidate to find solution for a complex calculation. It checks the ability of a student to deal with numbers. Questions of two different kinds are asked from this topic.
- Calculation is given and one of the numbers is missing from the calculation.
- Numbers are given with some operations between them and we have to simplify the calculation.
The questions under this category can be solved using the BODMAS rule.
2. Number series
In these questions, we have numbers which are written in a sequence thereby, making a number series. In order to answer such questions, we need to figure out the pattern that the number series follows. By applying this pattern to its predecessor, the missing value can be found. Another type of question under this category is where all the numbers are given and to find the number that is not following the pattern.
3. Quadratic equations
In these questions, there will be two quadratic equation, one which contains a variable x and another containing variable y. The value of x and y needs to be found out by solving the quadratic equations which is to be done individually.
4. Data interpretation
This is a time-consuming part in the quantitative aptitude section. The aim of these questions is to check the ability of the candidate to observe and calculate at the same time. The method to approach these questions is to first understand the small specifications and then look at the type of questions asked. Normally, these questions are given in the form of a pie chart, bar chart, line chart of tabular form.
a) Time and work
These questions are about finding the work done by a person or group of people or to find the time taken by these people to complete a work.
b) Time and distance
Questions on time and distance requires the candidate to find the time taken by an object to cover a distance while moving at a particular speed. Another type of question is to find the distance covered by an object in a given period of time while moving at a said speed. Third type of problem will be to find the speed of the object while covering a distance by taking a known amount of time. Keep in mind the formula, Speed = Distance/Time.
c) Simple and compound interest
This is a frequently asked topic in mist of the exams. These questions are meant to find out the simple interest and compound interest under various rate of interest, amount and time.
d) Profit and loss
These questions require the candidate to determine various parameters like Selling Price (SP), Cost Price (CP), Profit, Loss, Profit Percentage and loss percentage depending upon the question.
e) Ratio and proportion
The questions on ratio and proportion could be problems on age, partnership or mixture and alligation. The problems on age are those in which the age of two people (mostly between father and son) will have to determined depending upon the given ratio or other details. Partnership problems are those in which the share of a particular partner needs to be figured out or the ratio of the shares between the partners. Mixture and allegation problems are those in which the ratio in which two or more ingredients of different prices are mixed to produce a mixture of desired price.
f) Permutation and combination
Permutation and combination questions are those that require us to find various arrangements and combinations in which words or letters or a word can be arranged.
In these questions, the chances of occurrence of a particular event, or chances that a particular event might not happen needs to be determined. For example, chances of getting a head when you toss a coin, the probability of getting an even number when a dice is rolled.
These are the topics that will come under the quantitative aptitude section. Attempt as many questions as you can and increase your speed and accuracy. Use Entri app to help you in your preparation and watch yourself landing that dream job.
