There are 25 girls in a horizontal row. Rekha was shifted by three places towards her right side and now she occupies the middle position in the row. What was her original position from the left end of the row?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 10th
In a row of an odd number \(n\) of people, the middle position is \(\frac{n+1}{2}\)th from either end. The middle of 25 girls is the \(\frac{25+1}{2}=\) 13th place. She reached it after moving 3 places to her right, so she was 13 − 3 = 10th from the left.
