In this article, we will discuss Key Quantitative Aptitude Topics for PNB SO

Key Quantitative Aptitude Topics for PNB SO

Below are the key important topics that you should focus on while preparing for the Quantitative Aptitude section of the PNB SO 2025 exam. These topics are part of the official syllabus and carry significant weight in the exam.

Number Series
This topic includes a sequence of numbers where you have to find the missing number or identify the wrong one. Common patterns include addition, subtraction, multiplication, squares, cubes, and more. With regular practice, you can solve these questions quickly.

Simplification and Approximation
These questions test your ability to solve problems using basic arithmetic operations like addition, subtraction, multiplication, and division. You may also be asked to find approximate values. Strong calculation skills and understanding of BODMAS rules are important here.

Data Interpretation (DI)
In this section, you will be given data in the form of tables, bar graphs, pie charts, or line graphs. You must read the data carefully and answer the questions based on percentages, ratios, averages, or comparisons. DI is scoring if you are good at reading and analyzing data.

Quadratic Equations
You will be given two equations and asked to compare their roots. A good understanding of how to solve quadratic equations using factorization or the quadratic formula is needed. It is a common and scoring topic in the exam.

Arithmetic Word Problems
This is one of the most important parts of the Quant section. You need to read the question carefully and apply the right formula. These questions test your ability to apply concepts in real-life situations. It includes various topics like:

• Profit and Loss
• Simple and Compound Interest
• Time and Work
• Time Speed and Distance
• Ratio and Proportion
• Mixture and Allegation
• Averages
• Ages

Data Sufficiency
In this topic, you are given a question followed by two or more statements. You need to decide whether the statements provide enough information to answer the question. Logical thinking and a clear understanding of basic concepts are needed here.

Mensuration
This topic deals with areas, volumes, and perimeters of 2D and 3D shapes. Formulas for squares, rectangles, circles, cylinders, cones, and spheres should be memorized. It is an important part for exams with practical math problems.

Common Mistakes to Avoid in PNB SO Quantitative Aptitude Section

Avoiding these common mistakes can help you perform better in the Quantitative Aptitude section of the PNB SO exam and boost your chances of selection:-

• Many students lose marks in this section due to small mistakes. One common error is spending too much time on one question. If it takes longer, skip and return to it later.
• Another mistake is misreading the question. Words like not or maximum can change the meaning. Always read carefully before solving.
• Weak calculation speed also leads to wrong answers. Since calculators are not allowed in the PNB SO exam, practice mental math and shortcut methods regularly.
• Some candidates ignore basic topics and focus only on hard ones. But without strong basics, even easy questions become tough. Revise topics like percentages, ratios, and averages.
• Lastly, skipping mock tests is a major error. Mock tests help you practice under real exam conditions and improve your timing.
