Question
In a row of girls, Ramya is fifth from the left and Priya is sixth from the right. When they exchange their positions, then Ramya becomes thirteenth from the left. What will be Priyas position from the right?
Solution
Step 1: We know that Ramya is fifth from the left and when she exchanges her position with Priya, she becomes thirteenth from the left. This means that Priya was originally in the thirteenth position from the left.
Step 2: We also know that Priya is sixth from the right.
Step 3: To find Priya's new position from the right after the exchange, we need to calculate the total number of girls in the row. We can do this by adding Priya's original position from the right (6) to Ramya's new position from the left (13) and subtracting 1 (because we are counting Priya twice in this calculation).
So, the total number of girls in the row is 13 + 6 - 1 = 18.
Step 4: Now, to find Priya's new position from the right, we subtract Ramya's original position from the left (5) from the total number of girls (18) and add 1 (because we are starting the count from 1).
So, Priya's new position from the right is 18 - 5 + 1 = 14.
Therefore, after exchanging positions with Ramya, Priya will be fourteenth from the right.
