Number of Children	135	120	95	100	90	80

$(a)$. 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."

Given:

Number of children in six different classes are given.

To do:

We have to represent the data on a bar graph and answer the given questions.

Solution:

The bar graph of the given tabular data is below-

(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$=100$

Number of students in class sixth$=120$

The ratio of the number of students in class eighth to the number of students in class sixth

$=120:100$

$=6:5$
