Correct Answer: 12%
Solution :
Total students in the year 2021 = 60000
Mathematical Science students in 2021 = $\frac{68.4}{360}×60000=11400$
Total students in the year 2022 = 75000
Mathematical Science students in 2022 = $\frac{61.2}{360}×75000=12750$
Difference = 12750 – 11400 = 1350
Rate of change = $\frac{1350}{11400}×100=11.84 \approx12$%
Hence, the correct answer is 12%.
