The SSC CGL preparation for the Quantitative Aptitude section is important as it is the most important area, or you can say is the deciding area for a candidate in the merit list. It occupies the top spot in terms of the weightage it carries in the CBT. 50/200 in Prelims and 90/450 in paper 1 of tier 2 which makes it make it 140/650 or 21% of your success (or failure) in SSC CGL exam.
The questions in this section are designed to test the ability to appropriate use of numbers and number sense of the candidates. The scope of quantitative ability is clearly defined and is limited to class 10th-level mathematics. If you have good command over this section, you can score 40–45 marks. All you need to do is attempt the questions with good accuracy. The level of this section is expected to be moderate.
Note: It is important to analyze previous year papers and find out the break-up of questions. This will help you to find out which area needs more practice and time so that you can plan out your study schedule.
Topic-wise SSC CGL Math Preparation Tips
From the above table, we can see that most of the Quant paper is concentrated on the five topics- Trigonometry, Geometry, Data Interpretation, Algebra, Percentage/ Profit, Loss & Discount.
Generally, easy questions are asked on trigonometry in Tier I. So you need to prepare the basics. But remember the pattern of questions should be of SSC CGL. No other exam like NDA, CDA will work.
Do you need to learn so many formulas of Trigonometry?
The answer would be “NO”. You need not remember so many formulas, only 3-4 are enough. You need to remember the basics about sin θ, cos θ, tan θ, cot θ, Sec θ, cosec θ, and their relationship. Then 3 basic formulas and a table for θ value of the angle. The most important thing is you must fluent in the table as most of the questions can be solved by putting value. You need not solve the entire question, just put the value of θ and will get the answer.
Geometry in the SSC CGL exam is considered the most important topic. Most of the questions are directly related to properties. So, SSC CGL preparation for the Geometry topic can be done by revising the properties of Lines, Angle, Triangle, Quadrilateral, Polygon, Circle, Concept of Triplet, etc.
3. Data Interpretation
Nearly all the D.I. questions are based on ratio, percentage, and average chapters of arithmetic which you can easily solve within 3-4 minutes and score good marks.
It includes questions on Algebraic Identities, Factorization, Simplification of Polynomials, and Simplification of Fractions. Practicing all types of questions from these topics is a must. Algebra is closely connected to all other topics in the Quantitative Aptitude section. It will be useful in Data Interpretation, Geometry, Percentage, etc.
5. Percentage/ Profit, Loss & Discount
You should know the basic rules applied in these chapters. By heart learning formulas and their application would be a perfect way to solve many questions. Basic calculation and approximation concepts should be strong as they directly drive the candidate to the right option. Try to use shortcut tricks for saving time.
Solved just By taking 100 as base
Example: What is the percentage profit in selling an article at a discount of 20% which was earlier sold for 40% profit?
- a) 20%
- b) 14%
- c) 28%
- d) 12%
Solution: Let’s take Rs.100 as the cost of the article. The man was selling the article for Rs 140 (100 cost + 40 profit), now he is selling at a discount of 20%, now 140*20/100 = 28. New selling price = 140-28 = 112. Therefore, the answer is D.
Play with options
Example: A man bought 18 oranges for 100 rupees and sold 12 oranges for 100 rupees. Calculated profit percentage.
- Can’t be determined
It can be easily seen that man saved 50% of what he sold. He saved 6 oranges while he sold 12 oranges. Clearly, the answer is 50%.
There are a couple of mistakes done by aspirants while attempting the quantitative section in the SSC CGL exam. Enough practice to avoid these mistakes is included in the SSC CGL preparation strategy 2023 to score well in this section. Let us have a look at some common mistakes:
- Not Reading Questions Completely: In the quant section, this is the most common mistake made by students. In a hurry to solve questions faster, you don’t read questions clearly and end up making mistakes. This problem can cause frustration as even after solving the question methodically, you will not get the relevant option. And then, it becomes a herculean task to identify where you went wrong. Hence, read twice before you go ahead and start solving.
- Avoid Risky Shortcuts: If you have practiced a particular shortcut or trick on many questions during your preparation then go ahead. But, if you have just read some shortcut or any trick during the last leg of your preparation, avoid using it in the exam as you do not know the conditions in which this particular shortcut can be applied. Solve the question using a conventional way even if it takes more time.
- Guess Work: Absolutely avoid any guesswork as negative marking is the main point to be kept in mind as far as competitive exams are concerned.
