💡 Analysis & Explanation
Mathematical Ranking Principle ▼
When the exact position of a single individual is known from both extremities (top and bottom) of a linear sequence, the total count of the sequence is mathematically derived using a standard combinatorial formula.
Application of Formula ▼
The universally applied formula is: Total = (Position from Top + Position from Bottom) - 1. We subtract 1 to correct for counting the individual's specific position twice.
Execution ▼
Total = (38 + 15) - 1 = 53 - 1 = 52.
Conclusion ▼
There are exactly 52 students present in the class.
