Show answer & explanation
Correct answer: C
Key formula: Total students = position from one end + position from the other end − 1
Apply the formula with the given positions: position from one end = 25 and position from the other end = 23.
Total = 25 + 23 − 1 = 47.
Why subtract 1: when you add the two positions the same person is counted twice, so subtracting 1 corrects the double count.
Therefore, the class has 47 students.
