1. In a line of friends, Kantibhai is 5th from the left and Maniben is 6th from the right. When they interchange their places among themselves, Kanitbhai becomes 13th from the left. Then, what will be Maniben’s position from the right ?
2. In a queue of 10 boys when Ramdas was shifted by two places towards the left, he became 7th from the left end. What was his earlier position from the right end of the row ?
Since Kantibhai and Maniben interchange places, so Kantibhai ‘s new position (13th from left) is the same as Maniben’s earlier position (6th from right).
So, number of friends in the line = (13 + 6) – 1 (since Kantibhai and Maniben are in one of the positions) = 18. Now, Maniben’s new position is the same as Kantibhai’s earlier position i.e. 5th from left.
Maniben’s position from the right = (18 – 4 ) = 14th.
Number of boys in the queue = 10.
Ramdas’s new position is the row = 10.
Ramdas’s new position is 7th from the left or 4th from the right.
His earlier position was two places to the right of his new position i.e., his earlier position was second from the right.
