How to Prepare for CDS 2023 Mathematics By CDS Mathematics pdf
How to Prepare
In order to crack CDS, candidates must aim to score at least 65 marks in Elementary Mathematics paper.
Number system
Any candidate preparing for CDS 2021 from this section they can easily expect 15 to 20 questions . It can be said that almost this section constitutes about 15% of this paper. So candidates need to pay attention to every concept and method. Some easy tips to solve and prepare for number system:
Candidates can use NCERT books up to class 10th to clear the concept of Number System and it will help in completing the syllabus of CDS Number System as well.
- Solve at least 50 questions per day on this topic ranging from easy to high level of difficulty.
- The candidates need to focus on the questions related to HCF and LCM, finding out the product of the unit’s location and numbers.
Expected Number of Questions:
Basics of Number System: 5 Questions
LCM & HCF : 3 Qs
Serd & Index : 2 Qs
BODMAS : 3 Qs
Factor: 4 Qs
Elementary number theory
The things you should learn are Sum of natural numbers, Sum of squares, Sum of cubes, Divisibility tests and HCF and LCM along with some important formulas.
Algebra
17 – 20 questions out of 100 questions come from algebra. Basic operations, simple factors and remainder theorems are good topics to start preparing for algebra. Some tips and tricks to solve algebra problems faster:
Firstly, you should opt for easier methods, especially when you are practicing at home.
Sometimes in case of a lot of questions, taking variables can help as well as it can provide you a shortcut way to solve the problem in less time than it usually takes.
You must memorize all the important algebra formulas. At the very least you need to remember the logic behind the formulas so that when needed you can use logic instead of wasting time during the exam.
To master this topic, practice several different familiar types of questions. Once you start solving similar topics and previous years questions, it will give a rough idea of your progress and the logic behind the problems.

Trigonometry
Around 10-15 questions were asked from Trigonometry section in CDS Mathematics paper. Thus, the weightage of trigonometry in UPSC CDS exam is around 12-15%.
Some basic tips that you can follow while preparing for Mathematics:
- Although trigonometric ratios are more important, you should also know trigonometric identities.
- In the questions of height and distance, you should keep in mind the form of angle (angle of elevation or angle of depression) given in the particular question.
- Practice language-based questions that will help you with altitude and distance problems.
Geometry
Geometry is one of the most important sections of mathematics. CDS Mathematics paper consists of 15 – 20 questions from Geometry section. The geometry section can be divided into three subsections such as coordinate geometry; properties of lines and angles; and properties of triangles, circles, rectangles, squares etc.
Some of the topics practiced in parallel with coordinate geometry are circles, parallel lines, and triangles, with great emphasis on the congruence and similarity of triangles.
Write down the geometry formulas on a piece of paper and stick them on the wall where you can see them regularly. This will help you remember them.
Don’t waste your time trying to solve it right away, If you are stuck with a geometry question,. Instead, move on with the others and come back to that question when you’re done with the rest.
Mensuration
Mensuration actually deals with problems related to measurement involving columns, areas, lengths etc. From this topic, 13 to 15 questions are expected in CDS II 2021 exam.
- Clear your concepts about 2D and 3D dimensions and their related shapes.
- Most measurements are in decimal or require complex calculations. Due to haste, one can easily miscalculate them or make silly mistakes.
- Questions that involve calculating the cost of fences, floors, painting, etc. usually require a percentage increase or decrease in the measurement meter mentioned in the question or a figure inscribed within another figure, etc.
- Always remember the most important and essential formula. Most of the time, formulas can shorten the calculation or sometimes even simplify the problem.

Statistics
In CDS II 2021, maximum 8 questions can be expected from Statistics. It is quite easy if you have a clear concept. Statistics can be divided into three parts: General Statistics Terms, Frequency Distributions and Data Interpretations.
In General Statistics Terms, candidates should prepare for mean, median, mode, variance and standard deviation.
In case of frequency distribution, candidates basically need to understand some important components like class, class limit, class frequency and mean of frequency distribution etc.
Data representation refers to the given set of data in various forms such as pie chart, tabular form, bar chart, etc. There is no fixed formula for data representation. These types of questions basically require calculation of average, percentage, ratio and other types of data given.
