How to solve Line Charts Quickly
Concepts for Line Chart
- Data Points: These are individual data values at specific points in time or along a continuous scale. Each data point consists of two values: the x-coordinate (horizontal position) and the y-coordinate (vertical position).
- X-Axis: The horizontal axis represents the independent variable, typically time, a category, or a continuous scale.
- Y-Axis: The vertical axis represents the dependent variable, which can be any numerical value.
- Line Segments: Data points are connected by straight line segments, providing a visual representation of the data’s trend or pattern.
- Trends: Line charts are used to identify trends over time or along the x-axis. An upward-sloping line indicates increasing values, a downward-sloping line suggests decreasing values, and a horizontal line represents no change.
Steps to extract information from Line Chart
- Step 1: Write the title of the graph.
- Step 2 : Draw Both the Axis of the Graph.
- Step 3 : Plot the Data Elements.
- Step 4 : Plot Given Element Provided in Data.
- Step 5 : Draw a Straight Line.
The Graph is ready.

Questions and Answers to Solve for Line Chart quickly
Answer the questions based on the given line graph.
Question 1.
What would be the ratio of average runs of B in 1996 to the average runs of A in 1993?
A. 9 : 10
B. 10 : 9
C. 3 : 2
D. 15 : 13
Answer : 3:2
Explanation :
Average runs of B in 1996 = 60.
Average runs of A in 1993 = 40.
Required ratio = 60 / 40 = 3:2
Question 2 :
What would be the ratio of average runs of A in 1998 to the average runs of B in 1993?
A. 7 : 11
B. 11 : 7
C. 3 : 2
D. 15 : 13
Answer : 11:7
Explanation :
Average runs of A in 1998 = 55.
Average runs of B in 1993 = 35.
Required ratio = 55 / 35 = 11:7
Question 3 :
What percent A’s average run in 1995 is of B’s average run in 1998?
A. 68.2%
B. 70%
C. 67%
D. 69.2%
Answer : 69.2%
Explanation :
Average runs of A in 1995 = 45
Average runs of B in 1998 = 65
Therefore, Required %= 45/65 * 100 = 69.2%
Question 4 :
The average runs of ‘B’ per year is what percentage of the average runs of ‘A’ per year?(approximately)
A. 70%
B. 110%
C. 113%
D. 90%
Answer : 113%
Explanation :
Average runs of A = (25 + 40 + 35 + 45 + 50 + 60 + 55) / 7 = 44.285
Average runs of B = (40 + 35 + 45 + 50 + 60 + 55 + 65) / 7 = 50
Required % = 50 / 44.285 x 100 = 112.9% ≅ 113%
Question 5 :
Average runs of ‘A’ in 1996 is what percent of average runs of ‘B’ in 1992?
A. 75%
B. 63.64%
C. 133.33%
D. 125%
Answer : 125%
Explanation :
Average runs of B in 1992 = 40.
Average runs of A in 1996 = 50.
Required % = 50/40 * 100 = 125 %
