Introduction to Data Interpretation

Direction: The data given in Bar diagram relate to the department wise admission of 320 students to B.Sc. (Honours) first-year classes of a certain college in the given five subjects. Study the graph and answer the questions.

1. The subject which the female students are finding difficult as compared to other subjects is :

1. It is obvious from the bar diagram.
The percentage of females in Chemistry is least.

Correct Option: D

It is obvious from the bar diagram.
The percentage of females in Chemistry is least.
Thus , option D is correct answer .

1. The total number of male students who got admitted in Mathematics and Economics as compared to the total number of female students getting admission in Mathematics and Economics is :

1. 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

1. The difference of the choice of the subject between male and female students is maximum for the subject.

1. 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 chemistry

Correct 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
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 chemistry
Difference = 61 – 24 = 37
Hence , required subject is chemistry .

1. The subject in which the difference in the number of male and female students is minimum in :

1. On the basis of given graph in question ,
Number of male students in statistics = 15
Number of female students in statistics = 16
Required Difference = Number of female students in statistics – Number of male students in statistics

Correct Option: C

On the basis of given graph in question ,
Number of male students in statistics = 15
Number of female students in statistics = 16
Required Difference = Number of female students in statistics – Number of male students in statistics
Required Difference = 16 – 15 = 1

Direction: A constituency is divided in four regions A, B, C and D. Two candidates X and Y contested the last election from that constituency. The adjoining graph gives the break–up of voting in the four regions. Study the graph and answer the following questions.

1. Nearly what percentage of his total votes did X receive from region B?

1. According to given bar graph , we have
In region B , X gets votes = 73
Total votes received by X = 45 + 73 + 51 + 56 = 225
