Show answer & explanation
Correct answer: C
Concept
A part as a percentage of a whole is found by dividing the part by the whole and multiplying by 100.
For a table-based percentage, first add all categories for the required period, then compare the requested category with that total.
Application
For 2021, the total enrolment is 115 + 85 + 180 + 100 + 145 = 625.
The required fraction is CSE enrolment divided by total enrolment: 115/625.
Converting the fraction to a percentage gives (115/625) × 100 = 18.4%.
Cross-check
Taking 18.4% of 625 gives 0.184 × 625 = 115, which reproduces the CSE enrolment.
Therefore, the required percentage is 18.4%.
