The following line graph shows the yearly sales figures for a manufacturing company.

**(a)** What were the sales in

**(i)** 2002

**(ii)** 2006?

**(b)** What were the sales in

**(i)** 2003

**(ii)** 2005?

**( c)** Compute the difference between the sales in 2002 and 2006.

**(d)** In which year was there the greatest difference between the sales as compared to its previous year?

In the graph, we find that the years are represented on the x-axis and the sales (in ₹ crores) on the y-axis. The sales at any time (year) can be read from the graph exactly in the same way as we read the coordinates of a point. From the graph, we observe that :

**(a)**

**(i)** The sales in the year 2002 is ₹ 4 crore.

**(ii)** The sales in the year 2006 is ₹ 8 crore.

**(b)**

**(i)** The sales in the year 2003 is ₹ 7 crore.

**(ii)** The sales in the year 2005 is ₹ 10 crore.

**( c)** The difference between the sales in 2002 and 2006 = ₹ 8 crore – ₹4 crore = ₹ 4 crore.

**(d)** The year in which there was the greatest difference between the sales as compared to its previous year is the year 2005.
