CDS 1 2020 paper for Mathematics was difficult in terms of difficulty level. The questions asked in the exam were tricky and lengthy. The CDS Mathematics paper carries a total of 100 questions from topics like Number systems, Algebra, Trigonometry, Geometry, Mensuration, Simplification, Simple and Compound interest, Ratio & Proportion, Speed, Distance and Time, Work and Time, Set theory etc. The topic-wise analysis of questions is shown as below:
| Name of the Topic | Number of Questions |
| Number Systems | 12 |
| HCF and LCM | 2 |
| Square roots and Cube roots | 3 |
| Speed, Distance and Time | 3 |
| Work and Time | 2 |
| Percentage | 2 |
| Simple and Compound interest | 1 |
| Ratio and Proportions | 4 |
| Logarithms | 2 |
| Algebraic Operations | 4 |
| Rational Expressions | 1 |
| Linear Equations | 1 |
| Quadratic equations and Inequalities | 6 |
| Set theory | 2 |
| Trigonometry | 14 |
| Geometry | 15 |
| Mensuration | 19 |
| Statistics | 7 |
The paper consisted of maximum question from mensuration topic. Trigonometry maintains its number of questions in the usual range every year. But the different thing in CDS 2020 was geometry! 15 questions came from geometry segment this year.
So, basically the students who have prepared well for Geometry, Trigonometry, Mensuration and Number system were in advantage. However, the questions from other topics were lesser in number and easier to solve. Also, this year’s paper is quiet lengthy which implies that the student who can judge, which question should be attempted first, will make it through. One should be more focused to solve the questions using the given options rather than the traditional methods as per our advice in a paper like CDS 1 2020 !
