Question -
| 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 classeight.
Answer -
(a) We will take the scale as 1 unit = 10 children. Because, we can represent a better and clear difference among the number of students of class 7th and class 9th.
(b) (i) Class 5th has the maximum number of children i.e. 135 and class 7th has the minimum number of children i.e. 95.
(ii) The total number of students in class 6th is 120 and the total number of students in class 8th is 100
Then,
Ratio between the number of students of class 6th and 8th,
= (120/100)
= 6/5
= 6: 5
