उत्तर
a. We will choose a scale as 1 unit = 10 children because we can represent a more clear difference between the number of students of class 7th and that of class 9th by this scale.
b. i. Since the bar representing the number of children for class fifth is the tallest, there are maximum number of children in class fifth. Similarly, since the bar representing the number of children for class tenth is the smallest, there are minimum number of children in class tenth.
ii. The number of students in class sixth is 120 and the number of students in class eight is 100. Therefore, the ratio between the number of students of class sixth and the number of students of class eight
= `120/100`
= `6/5`
= 6 : 5
