Sagot :

To determine the total number of second-, third-, and fourth-year students at Central University, follow these steps:

1. Understand the student-to-faculty ratio:
- The student-to-faculty ratio is 12 to 1. This means that for every faculty member, there are 12 students.

2. Calculate the total number of students:
- Given that there are 154 faculty members,
- Total number of students = Number of faculty members × Student-to-faculty ratio
- Therefore, multiply the number of faculty members (154) by the student-to-faculty ratio (12).
- Total number of students = 154 × 12 = 1848

3. Identify the number of first-year students:
- It is given that there are 604 first-year students.

4. Calculate the number of second-, third-, and fourth-year students:
- Subtract the number of first-year students from the total number of students.
- Upper-year students = Total number of students - First-year students
- Upper-year students = 1848 - 604 = 1244

Therefore, the total number of second-, third-, and fourth-year students is 1244.
