Graphs are visual representations of data collected. In most cases, the data exists in the form of a table. In many cases, the table itself is displayed.
There are many different types of graphs.
a.Bar graph.
b.Pie graph or pie chart.
c.Line graph.
A linear graph is different from a line graph, in a linear graph, the rest of points on the graph line up in an orderly manner. A linear graph is a graph that consists of a single straight line segment graph obtained by joining the plotted points is a line. Such graphs are called linear graphs.
A line graph displays data that changes continuously over period of time. A line graph which is a whole unbroken line is called a linear graph. To draw such a line we need to locate some points on the graph sheet

Solution:
(a) The sales in:
(i) Year 2002 was ₹.4 crores
(ii) Year 2006 was ₹ 8 crores.
(b) The sales in:
(i) Year 2003 was ₹7crores
(ii) Year 2005 was ₹10 crores.
(c) The difference of sales in Year 2002 and Year 2006
= ₹ 8crores – ₹ 4crores
= ₹ 4crores
(d) In the year 2005, there was the greatest difference between the sales as compared to its previous year, which is (₹10 crores – ₹ 6 crores) = ₹ 4 crores.
