Observe the following data:
| Class | Total Students | Number of Students Present on that Day |
|---|---|---|
| VI | 90 | 81 |
| VII | 82 | 76 |
| VIII | 95 | 91 |
| IX | 70 | 65 |
| X | 63 | 62 |
(a) Draw a double bar graph choosing an appropriate scale. What do you infer from the bar graph?
(b) Which class has the maximum number of students?
(c) In which class, the difference of total students and number of students present is minimum?
(d) Find the ratio of number of students present to the total number of students of Class IX.
(e) What per cent of Class VI students were absent?
(a) Give the double bar graph here
(b) VIII
(c) X
(d) 13:14
(e) 10%
(b) Max total = 95 in VIII.
(c) Difference smallest for X (63−62=1).
(d) Ratio IX = 65/70 = 13/14.
(e) Absent VI = (90−81)/90 = 10%.
