On the basis of given graph in question ,
Number of the students in section C = 31
Total number of the students in class VI = 34 + 35 + 31 + 32 + 33 + 34 = 199Required percentage = Number of the students in section C × 100 Total number of the students in class VI
Correct Option: D
On the basis of given graph in question ,
Number of the students in section C = 31
Total number of the students in class VI = 34 + 35 + 31 + 32 + 33 + 34 = 199Required percentage = Number of the students in section C × 100 Total number of the students in class VI Required percentage = 31 × 100 = 15.57% 199

From the given bar graph , we have
Number of the students in section B = 35
Number of the students in section C = 31
Required ratio = Number of the students in section B : Number of the students in section CCorrect Option: C
From the given bar graph , we have
Number of the students in section B = 35
Number of the students in section C = 31
Required ratio = Number of the students in section B : Number of the students in section C
Required ratio = 35 : 31
