In a class of 50 students, among the students who passed, Preet secured the 15th position from the top and the 13th position from the bottom. How many students failed in the exam?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 23
Preet’s ranks are counted only among the students who passed. A rank from either end includes the person, so number passed = rank from the top + rank from the bottom − 1.
15th from the top: 14 passed students above Preet
13th from the bottom: 12 passed students below Preet
Students who passed \(=14+1+12=27\)
Students who failed \(=50-27=23\)
