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

Class | Fifth | Sixth | Seventh | Eighth | Ninth | Tenth |

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

$=120:100$

$=6:5$
