Question

The following data gives the production of foodgrains (in thousand tonnes) for some years:

Year	1995	1996	1997	1998	1999	2000
Production (in thousand tonnes)	120	150	140	180	170	190

Represent the above data with the help of a bar graph.

Answer 1

1. Mark the horizontal axis OX as “Years” and the vertical axis OY as “Production of foodgrains (in thousand tonnes)”.

2. Along the horizontal axis OX, choose bars of uniform (equal) width, with a uniform gap between them.

3. Choose a suitable scale to determine the heights of the bars, according to the space available for the graph.Here, we choose 1 big division to represent 20 thousand tonnes.
