table​

Answer 1

Answer:

In the graph, we find that the years are presented on the x-axis and the sales (in Rs. 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:

        (i) (a) The sales in the year 2002 is Rs. 4 crore.

        (b) The sales in the year 2006 is Rs. 8 crore.

        (ii) (a) The sales in the year 2003 is Rs. 7 crore.

        (b) The sales in the year 2005 is Rs. 10 crore.

        (iii) The difference between the sales in 2002 and 2006 = Rs. 8 crore - Rs. 4 crore = Rs. 4 crore.

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