According to given bar graph , we have
In Economics and Mathematics :
Total male students = 30 + 32 = 62
Total female students = 20 + 34 = 54
Difference = 62 – 54 = 8∴ Required percent = Difference × 100 Total female students
Correct Option: C
According to given bar graph , we have
In Economics and Mathematics :
Total male students = 30 + 32 = 62
Total female students = 20 + 34 = 54
Difference = 62 – 54 = 8∴ Required percent = Difference × 100 Total female students Required percent = 8 × 100 54
∴ Required percent = 14.8% more

From the given bar diagram , we see that the difference of the choice of the subject between male and female students is maximum for the chemistry subject
Number of male students in chemistry = 61
Number of female students in chemistry = 24
Required Difference = Number of female students in chemistry – Number of male students in chemistryCorrect Option: D
From the given bar diagram , we see that the difference of the choice of the subject between male and female students is maximum for the chemistry subject
