Answer 2

In bar graph, bar of uniform width are drawn  with equal spacing between them on one  Axis with various Heights.

___________________________________________________________

Solution:

i)

We draw the bar graph of this data, note  that the unit in the second column is seats won by political party.

a)

We represent the political party on the horizontal Axis choosing any scale , Since width of the bar is not important but for clarity we take equal widths for all bars and maintain equal gaps in between.

Let one political party be represented by one unit.

 

b)

We represent the seats won  on the vertical Axis . Here, we can choose the scale as 1 unit =10 seats

Now the graph is as shown in the attachment

 

From the graph it is clear that  party A won the maximum number of seats i.e. 75

Hence, party 'A' won the maximum number of seats i.e.75.
