Correct Answer: 11.1%
Solution :
The number of science students in 2007-08 = 500
The number of science students in 2006-07 = 450
Percentage change =$\frac{\text{Number of science students in 2007-08 - Number of science students in 2006-07}}{\text{Number of science students in 2006-07}}\times100$
Percentage change = $\frac{500- 450}{450}\times100$
Percentage change = $\frac{50}{450}\times100$ = 11.1%
Hence, the correct answer is 11.1%.
