The Correct Option is C
Solution and Explanation
- Step 1: Calculate total for 2011. Sum: $50 + 60 + 40 + 30 = 180$.
- Step 2: Calculate total for 2012. Sum: $55 + 65 + 45 + 35 = 200$.
- Step 3: Calculate total for 2013. Sum: $60 + 70 + 50 + 40 = 220$.
- Step 4: Compare totals. 2013: 220, 2012: 200, 2011: 180. 2013 has the highest enrolment.
