In a class of 45 students, no two students share a rank in any subject. Rehana is 12th from the top in History. In Geography, her rank is 10 places lower than her History rank. What is her rank in Geography from the bottom?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 24th
A lower rank means a larger number from the top. Find the Geography rank from the top, then use rank from the bottom = total − rank from the top + 1.
History rank from the top: 12th
Geography rank from the top \(=12+10=22\)nd
Geography rank from the bottom \(=45-22+1=24\)th
