# Topic-Wise Analysis of Quantitative Aptitude for SSC CGLE Tier II The Staff Selection Commission conducts the SSC CGL every year for the recruitment of eligible candidates for Group B and Group C positions in various Ministries of Government.

In most competitive exams, including the SSC CGL, quantitative aptitude is arguably the most scoring section. To maximise your score in the SSC CGL Tier-II, you must answer quantitative aptitude quickly and accurately. In this context, your preparation should focus on enhancing both conceptual knowledge and calculation speed.

On that note, let’s go over a topic-wise breakup of questions in the Quantitative Aptitude section in SSC CGL Tier-II

## Mensuration

Mensuration is one of the most important topics because it is the foundation for 12–15 questions. Because the majority of these questions require direct formula application, you must get familiar with a variety of formulae through persistent practise.

You can also memorise all formulae and applications relating to the Equilateral Triangle, Trapezium, Circle, Cone, Cylinder, Sphere, Frustum, and Pyramid.

You must understand the logic behind all formulas to avoid any confusion and in turn silly mistakes. For example, one can confusingly use the formula of Circumference of a Circle instead of the Area formula because of the lack of understanding of their derivation.

## Geometry

The basic features of various geometric figures are directly related to the most of the 8-10 exam questions (that focus on this area). Equilateral triangles, the Basic Proportionality Theorem, geometric points like centroid, the relationship between circum-radius and in-radius in an equilateral triangle, the sum of internal and external angles in a polygon, angles in a semi-circle, alternate segment theorem, direct and transverse common tangents are some of the most common topics covered.

## Percentages and Profit and Loss

This topic is covered in roughly 16 to 20 questions on the exam. This topic’s questions revolve around the use of percentages and the relationship between cost, selling price, discount, and marking price. The types of questions are typically repetitious and manageable.

## Algebra

In this topic, there are usually 8 to 10 questions. Important equations must be remembered in order to answer these questions. The majority of the problems are centered on Algebraic Identities, Factorization, Polynomial Simplification, and Fraction Simplification.

## Time and Work, and Time and Distance

For the past five years, around ten questions have been asked about these two themes. Almost every exam includes a question about pipes and cisterns, boats and streams, and railways.

## Trigonometry

It has been noticed that this issue produces approximately 8 to 10 questions, with two questions based on heights and distances being the most common.

## Data Interpretation

A minimum of 5 questions and a maximum of 7 questions are normally asked from this topic. Tables, bar graphs, pie charts, and line graphs are among the ‘common DI’ types. Most DI questions have used tables, bar graphs, and pie charts in the last five years. Simple calculations are required for these problems, which include the use of percentages, ratios, and averages.

Data interpretation is usually one of the easier areas to master, and it is easy to get a perfect score. In 2018, students were asked three questions about bar graphs, pie charts, and histograms. The difficulty level of these questions ranged from moderate to challenging.

## Miscellaneous

It has been observed that in the previous five years, on average, five questions were asked on Numbers, but in the last two years, ten questions have been asked. In the last three years, five questions on averages, mixtures, and allegations, as well as about five questions on ratio, percentage, and variations, have been posed.

A question on LCM and HCF, as well as a handful of questions on the equation of division and divisibility rules, are typical in Numbers. Divisibility rules have been the subject of several questions in recent years. There is also a question based on the remainder theorem’s application.
