Question

The following table shows the market position of different brands of soaps. Draw a bar graph to represent this data.

Brand	A	B	C	D	Other
Percentage of buyers	45	25	15	10	5

Answer 1

We can draw the bar graph by following the given steps:

Step 1.- On a graph paper, draw a horizontal line OX as x-axis and vertical line OY as y-axis.

Step 2.- Along OX, write the names of the brands at the points that are taken at a uniform gap.

Step 3.- Choose the scale:
1 big division = 5%
2 small divisions = 1%

Step 4.- Heights of the various bars:
A = 90 small divisions = 9 big divisions
B = 50 small divisions = 5 big divisions
C = 30 small divisions = 3 big divisions
D = 20 small divisions = 2 big divisions
Others = 10 small divisions = 1 big division

Step 5.- Draw bars of equal width on the x-axis. The difference between the two bars should also be the same.

We get the following bar graph:
