Quantitative Aptitude is the most important requisite for clearing any competitive exam. Quantitative Aptitude skills form the bulk of most of the graduate level papers. Let us jump this hurdle through an exhaustive coverage of all the Quantitative Aptitude topics and an in-depth understanding of this subject: (1) Data Interpretation : It is the process of making sense out of a collection of data that has been processed. This collection may be present in various forms like : - Bar Graph - Line Chart - Tabular Form - Caselet Form - Radar/Web - Pie Chart - Missing Data Interpretation (2) Percentages : Percentage is a way to express numbers in the base of a fraction of 100. Percentage forms a very important and vast part of the quantitative aptitude section. - Percent to Decimal or Fraction Conversion - Percentage of Quantity - Inverse Case – Value From Percentage - Percentage Change - Relative Percentage - Product Constancy - Consecutive Increments - Consecutive Decrease - Problems Based on Population - Results on Depreciation (3) Arithmetic Aptitude : In the Arithmetic Aptitude test, the questions are based on the concepts of Quadratic Equations, Approximations and Simplifications, Data Sufficiency, and HCF and LCM. - Quadratic Equations - Approximations and Simplifications - Data Sufficiency - HCF and LCM (4) Simple Interest and Compound Interest : Want to turn yourself into a compound interest calculator? Here in this section, we will see what we mean by the simple interest and the compound interest. - Simple Interest - Compound Interest with a Fractional Rate - Data Sufficiency - Difference Between Compound Interest and Simple Interest (5) Work And Time : Work And Time problems will focus on checking your aptitude through the concepts and questions that are on the concepts of the rate of work and efficiency of an individual, a group or any other entity that does the work. - Work from Days - Days from Work - Efficiency And Ratios - Data Sufficiency (6) Probability : Probability is a fundamental concept in math and statistics. In this section of quantitative aptitude, we will learn about the concept of probability keeping in mind the type and level, of questions that are asked in all the crucial competitive exams. - Probability of Random Event - Mutually Exclusive Events - Equally Likely Events - Independent Events - Compound Events - Total Probability (7) Permutation and Combination : Permutation and Combination is a very important topic of mathematics as well as the quantitative aptitude section. - Factorial Notation - Permutations - Number of Permutations - Combination - Number of Combination (8) Ratios and Proportions : The ratio or the proportion of two quantities is an effective way to measure the relative magnitude of two quantities. - Propotion Of Quantities - Proportionals (Third, Fourth and Mean) - Comparison of Ratios - Invertendo, and Alternendo - Componendo, and Dividendo - Componendo-Dividendo - Duplicate Ratios - Variations (9) Stream Boat Problems : Stream Boat problems test you on the concepts of relative motion. - Downstream - Upstream (10) Pipes and Cisterns : In the Pipes and cistern section, you will have to answer questions about the rate at which we can fill a container with the help of a pipe. These questions on the use of pipes and cistern are similar to the concepts of work and time. - Inlet Pipes - Outlet Pipes (11) Inequalities : Inequality is a condition or an equation in mathematics that has the ‘<‘ or the ‘>’ sign in it. - Word Problems - Coded Inequalities - Quadratic Equations (12) Number Series : Number Series is a sequence formed out of numbers. It has to detect the rules that result in the formation of a number series. - Perfect Square Series - Perfect Cube Series - Geometric Series - Two Stage Type Series - Mixed Series - Missing Number Series - Wrong Number Series (13) Profit and Loss : The concepts in Profit and Loss play a fundamental role in the realm of economics and accounting. The chapter will discuss the important aspects of profit and loss like cost price, and fixed, variable and semi-variable cost, selling price, marked price, list price, margin etc. - Cost Price - Fixed, Variable and Semi-variable Cost - Selling Price - Marked Price - List Price - Margin - Dishonest Dealers and Faulty Weights - Percentage Loss - Percentage Gain - Discounts and Marked Price - Equivalent Discount - Equation-Based Questions - Goods Passing Through Successive Hands (14) Age Problems : Age Problems can be tricky! The concepts of age are based on the relations between the blood relatives and other people. They use the concepts of proportions, ratios, and other equations to test your aptitude abilities. - Ratio Based Age Problems - Equation Problems of Age - Proportion Based Age Problems (15) Time And Speed : The concepts of Time & Speed are very important from the exam perspective. It is about the formulae, the concepts and the various scenarios like the trains problems, the data sufficiency and the relative speed conversions etc. - Distance/Speed Relation - Train Problems - Data Sufficiency - Relative Speed and Conversions (16) Mensuration : Mensuration is the branch of math that deals with the problems of finding the areas of figures like the area of a triangle, area of quadrilaterals and other polygons etc. - Volumes and Areas - Results on Triangles - Results on Quadrilaterals - Data Sufficiency (17) Averages : Averages are a means of finding the central or the typical value of a set of data. Through the average, we can avoid taking each data point into consideration and instead focus on the average value that represents the typical magnitude of the data points. - Average - Average Speed - Data Sufficiency - Average of Number Series (18) Partnerships : In Partnerships, we study the business partners and their deals. The business started by two or more parties is often governed by an agreement or a contract. We call these business contracts the partnerships. Partnerships govern the division of profit and loss of a business. - Simple and Compound Partnerships - Ratio of Divisions of Gains - Working and Sleeping Partners - Data Sufficiency (19) Mixture and Alligation : Mixture and Alligation questions form a very important part of the quantitative aptitude section. - Alligation & Rule of Alligation - Mean Price (20) Coding and Decoding : Well being able to solve coding decoding questions within a minute is one way to go, filled with symbols and images, letter-letter coding, the Number Coding, Symbol Coding, Number-Letter mixed coding.
