Direction: Study the following graph carefully to answer these questions. Number of students in College A and College B over the years.
-
For which college(s) and in which year was the percent rise in number of students from the previous year the highest?
-
- College A in year 2004 and College B in year 2005
- Only College B in year 2004
- College A in year 2004 and College B in year 2004
- College A in year 2007 and College B in year 2004
- None of these
Correct Option: C
From above given graph , we can see that
Number of students from college A in 2003 = 20 × 103
Number of students from college A in 2004 = 40 × 103
Total increase in number of students in College A from 2004 to 2003 = 40 - 20 = 20 × 103
Percentage rise in number of students from college A in 2004
| = | total increase in number of students in College A from years 2004 to 2003 | x 100% |
| total number of students in College A in year 2004 |
| = | 20 × 103 | x 100 = 100 % |
| 20 × 103 |
And Number of students from college B in 2003 = 30 × 103
Number of students from college B in 2004 = 60 × 103
total increase in number of students in College B from years 2004 to 2003 = 60 - 30 = 30 × 103
Similarly,
Percentage rise in number of students from college B in 2004
| = | total increase in number of students in College B from years 2004 to 2003 | x 100% |
| total number of students in College B in year 2004 |
| = | 30 × 103 | x 100 = 100 % |
| 30 × 103 |
