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?

Solution

✅ Correct Option: 4

There are 25 girls in a horizontal row. After shifting, Rekha occupies the middle position.

For 25 girls in a row, the middle position is:

Middle position =25+12= \dfrac{25 + 1}{2}

Middle position =262= \dfrac{26}{2}

Middle position =13= 13

So after shifting, Rekha is at the 13th position from the left.


Rekha was shifted 3 places towards her right side to reach the 13th position.

Original position =13−3= 13 - 3

Original position =10= 10

Therefore, Rekha's original position was 10th from the left end of the row.

The answer is Option 4: 10th.
