    Box T is placed in even numbered position. Four boxes are placed between Box X and Box T. Box T is placed above Box X. Only two boxes are placed between the Box Z and Box V in which Box V is placed below Box Z. Box Z is placed in odd numbered position. Box Z is not placed above Box T. From above statements, Case 1: If Box T is placed at 8 th position and then Box X is placed at 3 rd position. Box Z is placed at 7 th position and Box V is placed at 4 th position. Case 1-S: If Box T is placed at 8 th position and then Box X is placed at 3 rd position. Box Z is placed at 5 th position and Box V is placed at 2 nd position. Case 2: If Box T is placed at 6 th position and then Box X is placed at 1 st position. Box Z is placed at 5 th position and Box V is placed at 2 nd position. Based on the above information, we get the initial table as follows Only one box is placed between the Box Y and Box W in which Box W is placed below Box Y. Box X is not placed above Box S.
