Years | Number of bicycles manufactured |
1998 | 800 |
1999 | 600 |
2000 | 900 |
2001 | 1100 |
2002 | 1200 |
Answer:
To draw a bar graph, we will use the following steps. (i) Firstly, draw two perpendicular lines, one is horizontal and one is vertical. Along the horizontal line, mark 'years' and along the vertical line mark 'number of books sold'. (ii) Now, take scale of 1 unit length = 100 bicycles along the vertical line and then mark the corresponding values. Also, the heights of the bars for various days are as follows:
(iii) Draw bars of equal width and of height calculated in Step (ii) on the horizontal line with uniform gap between them. Thus we get the following bar graph. (a) The maximum number of bicycles were manufactured in the bar is largest for 2002). (b) The minimum number of bicycles were manufactured in the year 1999 (because the bar is smallest for 1999). 1998 \[\frac{800}{100}=4\text{units}\] 1999 \[\frac{600}{100}=6\text{units}\] 2000 \[\frac{900}{100}=9\text{units}\] 2001 \[\frac{1100}{100}=11\text{units}\] 2002 \[\frac{1200}{100}=12\text{units}\]
