Solution:

1). ∵ 100 % = 360°
∴ 16% = (360 / 100) × 16 = 57.6°

2). 4% = Rs. 6000
∴ 16% = (6000 / 4) × 16 = Rs. 24000

3). Miscellaneous expenditure on one copy = Rs. 1848 / 5500
∴ 4% = (1848 / 5000) × (100 / 4) = Rs. 8.40

4). Year 2009 = passing percentage = 45 (everyone)

5). Difference in 2007 = 45 – 15 = 30%

6). Pocket money Rs. (50 – 80) = 20 students

7). Required number of students = 20 + 12 + 16 = 48

8). Total students in 2001 – 2002 = 1350
