Some girls were playing Kho-Kho while sitting in a row. Riti sits at sixth position from the left and Riya sits at fifth from the right. They both exchange positions and then Riti becomes tenth from the left. What will be the new position of Riya from the right end of the row?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 9th
After the exchange, each girl sits in the other’s old seat, so Riti’s new position is Riya’s old one. That seat is known from both ends, which gives the length of the row.
Riya’s old seat is 10th from the left (Riti’s new position) and 5th from the right (given)
Girls in the row \(=10+5-1=14\)
Riya now sits in Riti’s old seat, 6th from the left
From the right: \(14-6+1=9\)th
