Study the given graph and answer the question that follows.

The graph presents total number of students who opted for different subjects in a college.

What is the difference between the total number of student who have opted for ‘Biology and Mathematics’ & total number of students who have opted for ‘Civics and History"?

Correct option is D

Given:

The total number of students who opted for different subjects in a college

Solution:

The total number of students opted for ‘Biology and Mathematics’ = [(65+87) + (67+87)] = 306

The total number of students opted for ‘Civics and History’ = [(45+65)+(67+78)] = 255

Difference = 306 -255 = 51
