Given info:
Number of children in six different classes are given in the attachment
Represent the data in to bar graph answer the following questions ?
Explanation:
See the above attachment
Number of children in class V = 135
Number of children in class VI = 120
Number of children in class VII = 95
Number of children in class VIII = 100
Number of children in class IX = 90
Number of children in class X = 80
Total number of children = 620
1) Scale :-
Taking scale depends upon the given values in the given data .
For convenience we take 1 cm = 10 units for related given data
On X-axis taking classes and taking on Y-axis number of children
On taking Y-axis 1 cm = 10 units
2)
Class V has maximum number of children (135)
and Class X has minimum number of children (80)
3)
Number of children in class VI = 120
Number of children in class VIII = 100
Ratio = 120:100
⇛ 120/100
⇛ 12/10
⇛ 6/5
⇛ 6:5
Answer:-
The ratio of the children on class VI to VIII = 6:5
In bar graph the width of the all bars are equal.
In bar graph the lengths of the bars Proportional to the frequency of the corresponding class.
