A round table has seven chairs around it. The chairs are numbered 1
through 7 in a clockwise direction. Four friends, Aslam (A), Bashir (B), Chhavi (C), and
Davies (D), sit on four of the chairs. In the starting position, Aslam and Chhavi are sitting
next to each other, while for Bashir as well as Davies, there are empty chairs on either side of
the chairs they are sitting on.
The friends take turns moving either clockwise or counterclockwise from their chair. The friend
who has to move in a turn occupies the first empty chair in whichever direction they choose
to move. Aslam moves first (Turn 1), followed by Bashir, Chhavi, and Davies (Turns 2, 3, and
4, respectively). Then Aslam moves again followed by Bashir, and Chhavi (Turns 5, 6, and 7,
respectively).
The following information is known: 1. The four friends occupy adjacent chairs only at the
end of Turn 2 and Turn 6. 2. Davies occupies Chair 2 after Turn 1 and Chair 4 after Turn
5, and Chhavi occupies Chair 7 after Turn 2.
