The topic of Averages is one of the most fundamental yet highly scoring areas in the <a href="https://Staff Selection Commission Combined Graduate Level (SSC CGL)">Staff Selection Commission Combined Graduate Level (SSC CGL)</a> Quantitative Aptitude section. Whether you're preparing for Tier I or Tier II, questions from averages appear consistently across shifts in various forms, ranging from simple, direct formula-based problems to complex applications involving weighted averages, age-based scenarios, income-expense analysis, and error corrections. Due to its versatility and integration with other arithmetic concepts, mastering this topic is crucial for boosting your overall score in the exam. In this blog, brought to you by Quant Sir, we’ll cover everything you need to know about SSC CGL average questions, from core concepts and formulas to high-frequency patterns and previous year problems. We’ll also explore smart-solving tricks, real <a href="https://ssc.gov.in/home/notice-board">SSC CGL</a> level examples, and a variety of question types that can help you handle average-based issues of speed and precision. Whether you're a beginner aiming to build your basics or an advanced learner targeting accuracy and time management, this comprehensive guide is designed to help you excel. <h2 id="content-id-131799-0">SSC CGL Average Questions - What is Average?</h2> Average (Arithmetic Mean) = Total Sum of Items ÷ Number of Items It is the simplest way to represent a dataset with a single value that lies somewhere between the smallest and largest observations. Example: Find the average of 10, 15, 20, 25, 30, 35 <ul> <li>Sum = 135, Count = 6</li> <li>Average = 135 ÷ 6 = 22.5</li> </ul> In SSC CGL, the idea of average is extended far beyond basic number sets. You’ll find it applied in real-life contexts, such as the average age of a family, the average speed of a vehicle, or the average marks of students, often combined with topics like ratios, percentages, or time and work. While the concept may seem simple, the exam often tests your ability to manipulate averages logically, especially when new members are added or removed, values are misread, or groups are merged. That’s why it’s essential not just to memorize the formula but to understand its practical application across various question types. <h2 id="content-id-131799-1">SSC CGL Average Questions - Importance</h2> The topic of SSC CGL average questions is a key component of the Quantitative Aptitude section and appears in almost every shift of the Tier-I exam. These questions are typically based on simple formulas but are often twisted using logical reasoning, making them both scoring and slightly challenging. Whether it’s finding the average of a set of numbers, calculating the effect of replacing a member in a group, or solving real-life problems involving averages of age, weight, or salary, these questions test a candidate’s conceptual clarity and speed. Moreover, mastering SSC CGL average questions helps candidates build a strong foundation in arithmetic and enhances their problem-solving ability across multiple topics. Since these questions are often mixed with practical scenarios, they are also helpful in building real-world quantitative aptitude. Regular practice under guided mentorship, such as from Quant Sir, can ensure accuracy and boost confidence in attempting these questions efficiently during the actual exam. <img loading="lazy" alt="SSC CGL Average Questions" src="https://www.quantsir.com/admin/assets/uploads/ckeditor/SSC_CGL_Average_Questions.webp" style="height:338px; width:600px"> [Source: Quant Sir] <h2 id="content-id-131799-2">SSC CGL Average Questions - Basic Formulae</h2> To solve SSC CGL average questions quickly and accurately, it's essential to memorize and apply a few core formulas that form the foundation of this topic. <table border="1" cellpadding="1" cellspacing="1" style="width:320px"> <tbody> <tr> <td style="text-align:center">Type</td> <td style="text-align:center">Formula</td> </tr> <tr> <td style="text-align:center">Average</td> <td style="text-align:center">Sum of all terms ÷ Number of terms</td> </tr> <tr> <td style="text-align:center">Average of the First 'n' Natural Numbers</td> <td style="text-align:center">(n + 1)/2</td> </tr> <tr> <td style="text-align:center">First n Even Numbers</td> <td style="text-align:center">(n + 1)</td> </tr> <tr> <td style="text-align:center">First n Odd Numbers</td> <td style="text-align:center">n</td> </tr> <tr> <td style="text-align:center">AP Series</td> <td style="text-align:center">(First term + Last term)/2</td> </tr> <tr> <td style="text-align:center">Square of the First 'n' Natural Numbers</td> <td style="text-align:center">[n(n + 1)(2n + 1)]/6</td> </tr> <tr> <td style="text-align:center">Cubes of the First 'n' Natural Numbers</td> <td style="text-align:center"> [{n(n + 1)}/2]2</td> </tr> </tbody> </table> <h2 id="content-id-131799-3">SSC CGL Average Questions - Concepts and Formulae</h2> Understanding the core concepts and practicing diverse examples is the key to mastering SSC CGL average questions, as they range from basic calculations to logic-based applications seen in the actual exam. <h3>1. Basic Average Calculation</h3> These are straightforward, formula-based questions. Example 1: What is the average of the first 5 even numbers? Even Numbers: 2, 4, 6, 8, 10 → Sum = 30 → Average = 30 ÷ 5 = 6 Example 2: A cricketer scores 35, 56, 45, 43, 67, 70, and 48.

Avg salary = 80K. What’s the average of the rest 10%? → Let x be the average of the rest. → 0.7 × 50000 + 0.2 × 80000 + 0.1x = 80000 → x = 2.9 lakhs <h3>3.

<h2>SSC CGL Average Questions - Concepts and Formulae</h2>

Understanding the core concepts and practicing diverse examples is the key to mastering SSC CGL average questions, as they range from basic calculations to logic-based applications seen in the actual exam.

<h3>1. Basic Average Calculation</h3>

These are straightforward, formula-based questions.

Example 1: What is the average of the first 5 even numbers?

Even Numbers: 2, 4, 6, 8, 10 &rarr; Sum = 30

&rarr; Average = 30 &divide; 5 = 6

Example 2: A cricketer scores 35, 56, 45, 43, 67, 70, and 48. Find the average.

&rarr; Sum = 364, Count = 7

&rarr; Average = 364 &divide; 7 = 52

Quant Sir Tip: Use the deviation method to simplify calculations using a reference value (R).

<h3>2. Weighted Average</h3>

When groups with different counts are combined, use:

Weighted Average = [(m &times; a) + (n &times; b)]/(m + n)

Where m, n = number of items; a, b = respective averages

Example 1: Average age of 17 girls = 20; 23 boys = 22

&rarr; Weighted Avg = (17 &times; 20 + 23 &times; 22) / 40 = 21.15 years

Example 2: 70% of employees earn 50K; 20% earn 80K. Avg salary = 80K. What&rsquo;s the average of the rest 10%?

&rarr; Let x be the average of the rest.

&rarr; 0.7 &times; 50000 + 0.2 &times; 80000 + 0.1x = 80000

&rarr; x = 2.9 lakhs

<h3>3. Average in Replacement Questions</h3>

When a person/item is replaced:

New Value = Replaced Value &plusmn; (Change in Average &times; Total Members)

Example 1: The Average weight of 5 men drops by 3 kg when a 150 kg person is replaced.

&rarr; Drop = 3&times;5 = 15 &rarr; New person = 150 &ndash; 15 = 135 kg

Example 2: In a group of 30 people, avg drops by 2 when a person is replaced.

&rarr; Drop = 2&times;30 = 60 &rarr; Replaced person &ndash; new person = 60

Quant Sir Tip: Use a deviation-based formula to save time.
