A) 5000
B) 42000
C) 33000
D) 21000

Answer 1

Hint: The given graph is a line graph (as the manufacturing of different companies is represented by lines) from the observation of which we can calculate the difference between the number of vehicles manufactured by company Y in 2000 and 2001.

Complete step-by-step answer:
The co-ordinates mentioned on the lines are points on the y-axis showing the number of vehicles manufactured by respective companies.
Each point represents: value X 1000 number of vehicles manufactured (given)

In the graph, Years are given on the x - axis and the number of vehicles sold is on y - axis.
For company Y (denoted by red line), the number of vehicles sold can be observed by as:
Since the coordinates of y – axis are mentioned on the graph, the number of vehicles manufactured in year 2000 and 2001 are:
2000 🡪 128000 [As vehicles are given in 1000 each coordinate will mean 1000 vehicles]
2001 🡪 107000
The difference between them is given as:
128000 – 107000 = 21000
Therefore, the difference between the number of vehicles manufactured by company Y in 2000 and 2001 is 21000, option D).
So, the correct answer is “Option D”.

Note: Line graphs are used for representing the data visually and is preferred over other graphs for the observation of minor changes.
The actual numbers for the data points are known as data values.
Generally, the data points are represented by x - axis and the numerical value by y - axis.
