(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.

(i) We will take the scale as 1 unit = 10 children.

(ii) (a) Fifth class has the maximum number of children i.e., 135.

(b) Tenth class has the minimum number of children i.e., 80.

(c) Number of children in class eight = 100
Therefore Ratio of class sixth to the students of class eighth

120/100= 6/5= 6:5
