The Line Graph is an essential element of the Data Interpretation (DI) section within the Quantitative Aptitude part of the <a href="https://ssc.nic.in/">SSC CGL</a> (Staff Selection Commission Combined Graduate Level) exam. Whether you're targeting Tier 1 or Tier 2, mastering line graph questions can greatly enhance your ability to score well. These questions challenge your skills in identifying trends, drawing comparisons, and analyzing numerical data in a visual format. Although SSC CGL Line Graphs may appear straightforward, solving them accurately and quickly requires a strong grasp of basic arithmetic and analytical thinking. Over the years, SSC CGL Line Graph-based questions have consistently featured in <a href="https://ssc.gov.in/tender">SSC</a> CGL papers, especially in Tier 1, where you can expect around 3 to 5 questions from this topic. Their popularity comes from their practical nature—they reflect real-world scenarios like sales trends, pricing comparisons, or performance tracking. You can refer to our previous blog for a detailed explanation of <a href="https://www.quantsir.com/data-interpretation/ssc-cgl-line-graph-topics-and-weightage">Single Line Graphs</a>, while in this blog, we’ll focus on Double or Triple Series SSC CGL Line Graph. <h2 id="content-id-166324-0">SSC CGL Line Graph - Double or Triple Series Line Graphs</h2> Unlike single-line graphs that represent data for only one entity over a given time or category, double or triple series line graphs feature two or three data sets plotted simultaneously on the same graph. Each series is represented by a different line—often distinguished by color, shape, or line style (e.g., dotted, dashed, solid). These types of SSC CGL Line Graph are used to: <ul> <li> Compare performance across multiple items (e.g., sales of three companies over six months) </li> <li> Track changes or trends for each item over the same timeline </li> <li> Analyze interrelationships between different variables. </li> </ul> <h2 id="content-id-166324-1">SSC CGL Line Graph – Type of Questions</h2> SSC CGL Line Graph - double or triple line graph sets usually contain 5 to 6 questions in Tier 2. The questions are designed to evaluate analytical reasoning, data comparison, and numerical ability. Here are common question types: <ul> <li> Direct Comparison Questions: Compare values for different entities in the same period (e.g., Which company had the highest profit in March?). </li> <li> Cumulative Analysis Questions: Calculate total values over multiple periods or for all entities combined (e.g., Total sales of A and B from Jan to June). </li> <li> Percentage-Based Questions: Compute the percentage increase/decrease between time intervals for a specific entity or between entities. </li> <li> Ratio and Proportion Questions: Find the ratio of values between two different data series in the same or different years. </li> <li> Trend Identification Questions: Identify periods where values increased/decreased simultaneously or crossed over. </li> </ul> <img loading="lazy" alt="SSC CGL Line Graph – Type of Questions" src="https://www.quantsir.com/admin/assets/uploads/ckeditor/SSC_CGL_Line_Graph_Type_of_Questions.webp" style="height:225px; width:400px"> <h2 id="content-id-166324-2">SSC CGL Line Graph - Example Questions with Solutions</h2> SSC CGL Line Graph questions can appear in different formats—some involving just a Single dependent variable, while others may include two or more.

Trend of consumption of two types of metals (in units) by the state over some time <img loading="lazy" alt="Example 1" src="https://www.quantsir.com/admin/assets/uploads/ckeditor/SSC_CGL_Line_Graph_E1.webp" style="height:245px; width:400px"> [Source: Quant Sir] (1) The number of years for which the consumption of metal B was more than the consumption of metal A in the given period was ________. (2) The total consumption of metal A divided by the total consumption of metal B over the period will give a ratio equal to? (3) For the two data series shown above, how many years have there been a decrease in consumption? Sol: (1) [Attention] Here we can simply note down all the values and compare them, but we don’t need to do that. What we have to do is just check which year Metal B’s line is higher than Metal A’s, which is in 2011 and 2012, so our answer is 2. (Ans.) (2) For this, you have to calculate the total consumption of each metal. Consumption of metal A = 25 + 20 + 20 + 20 + 25 + 30 = 140 Consumption of metal B = 20 + 10 + 25 + 30 + 25 + 10 = 120 Ratio would be = 140 : 120 = 7 : 6 (Ans.) (3) Total consumption of metal A and B: In 2009 ⇒ 20 + 25 = 45 units In 2010 ⇒ 20 + 10 = 30 units In 2011 ⇒ 20 + 25 = 45 units In 2012 ⇒ 20 + 30 = 50 units In 2013 ⇒ 25 + 25 = 50 units In 2014 ⇒ 30 + 10 = 40 units A decrease in total consumption occurred in two years (2010, 2014).

Carefully read the title, legends, and axis labels to identify what is being represented. This clarity ensures that you interpret the values and comparisons correctly. </li> <li> Identify Patterns and Trends: Examine the overall structure of the lines.

Pay close attention to the intervals—whether they increase by 1, 5, 10, or more. Misreading the scale is a common mistake that can lead to incorrect answers, even if the approach is right. </li> <li> Use Estimation to Eliminate Options: In many questions, especially in Tier 1, approximation is not only acceptable but often encouraged. By estimating values from the graph and comparing them with the options, you can eliminate incorrect choices quickly and arrive at the right answer faster. </li> <li> Manage Combined or Multi-Format Graphs Wisely: In Tier 2, line graphs may be presented alongside bar charts or tables.

Ratio would be = 140 : 120 = 7 : 6 (Ans.)

(3) Total consumption of metal A and B:

In 2009 &rArr; 20 + 25 = 45 units

In 2010 &rArr; 20 + 10 = 30 units

In 2011 &rArr; 20 + 25 = 45 units
