# Number of children in six different classes are given below. Represent the data on a bar graph

(a) How would you choose a scale?

(b) Answer the following questions:

(i) Which class has the maximum number of children? And the minimum?

(ii) Find the ratio of students of class sixth to the students of class eight

**Solution:**

After drawing the bar graph, we can easily find the required information.

a) Scale on y-axis is 1 unit = 10 children

b) (i) Fifth class has the maximum number of children i.e. 135

The tenth class has the minimum number of children i.e. 80

Number of students in class sixth = 120

(ii) Number of students in class eighth = 100

Ratio = Number of students in class sixth

Number of students in class eighth = 120 : 100 = 6:5 = 6 : 5
