Read the bar graph carefully and answer the following questions.
(a) What is the scale chosen on the horizontal line representing the sale of number
of trousers?
(b) On which day were the maximum number of trousers sold? How many trousers
were sold on that day?

(c) On which day were the minimum number of trousers sold? What is their
number?
(d) How many trousers were sold on Monday?

Solution: (a) Scale on the horizontal line, X-axis: 1 unit = sale of 5 trousers.
(b) The maximum number of trousers were sold on Saturday, i.e., 65 trousers.
(c) The minimum number of trousers were sold on Wednesday, i.e., 20 trousers.

(d) 40 trousers were sold on Monday.
Example 5: The table given below shows the number of children who like to play different
sports in a locality.

Sport Badminton Hockey Cricket Chess Football
Number of Children 45 30 35 10 20

Represent the given data using bar graph.

Solution: Step 1: Choose an appropriate scale for the graph. To do so, note the highest and
the lowest values of the data. Then choose a scale that can fit the highest
value easily on the graph and make the bar with the lowest value clearly
visible. Here, 5 or 10 can be chosen as the scale for the given data.
Scale: X-axis: 1 unit = Preferred sport Y-axis: 1 unit = 5 children
Step 2: On a square paper, draw a horizontal line and label it as X-axis. Similarly,
draw a vertical line and label it as Y-axis.

Step 3: Draw bars of equal width but different heights on the horizontal axis
based on the given data.
Step 4: Leave equal space between two bars. Give a suitable title to the bar graph.
