Example 11: On the basis of a survey, it is found that in a day about 1,000 trucks, 700 buses, 2,500
cars, 4,500 two wheelers and 2,000 cycles pass through a road leading to Bhopal.

Draw a bar graph to represent 1 unit length = 500 vehicles
the above information. 5,000
4,500
Solution: By following the steps of 4,000
construction learnt earlier, 3,500
we obtain the bar graph Number of vehicles 3,000
given alongside. 2,500
On observing the bar graph, 2,000
1,500
it is clear that the maximum 1,000
number of vehicles passing 500
are two wheelers and the 0 Trucks Buses Cars Two Cycles
minimum number of vehicles wheelers
passing are buses. Type of vehicles

Example 12: The following table shows the number of bicycles
manufactured in a factory during the years 2002 to Years Number of bicycles
manufactured
2006. Illustrate this data using a bar graph taking 2002 3,000
scale of 1 unit = 2000 bicycles. 2003 2,000

(a) In which year were the maximum number 2004 6,000
of bicycles manufactured? 2005 11,000
(b) In which year were the minimum number of 2006 13,000
bicycles manufactured?

Solution: By following the steps of Scale: 1 unit length = 2,000 bicycles
construction learnt earlier, 14,000
we obtain the bar graph 12,000
represent ing the production
of bicycles during the years 10,000
2002 to 2006. Number of bicycles manufactured 8,000
(a) In the year 2006 6,000
maxi mum number 4,000
of bicycles were 2,000
manufactured.
(b) In the year 2003 0 2002 2003 2004 2005 2006
mini mum number of Years
bicycles were manufactured.
