1. Study the following graph carefully and answer the questions that follow:
No. Of students (in thousands) who opted for Three Different Specializations during the Given Five Years in a University.

If the total number of students in the university in the year 2007 was 455030, the total number of students who opted for the given three subjects was approximately what percent of the total students?
Total number of students = 455030
Number of those choosing the given three subjects
= 15000 + 10000 + 15000
= 40000
∴ Required percentage
No. Of students (in thousands) who opted for Three Different Specializations during the Given Five Years in a University.

If the total number of students in the university in the year 2007 was 455030, the total number of students who opted for the given three subjects was approximately what percent of the total students?
Solution:
In 2007, we have:Total number of students = 455030
Number of those choosing the given three subjects
= 15000 + 10000 + 15000
= 40000
∴ Required percentage
