Twelve boxes O, P, Q, R, S, T, U, V, W, X, Y, and Z are placed one above the other in two different stacks named stack A and stack B in six different shelves such that the bottom-most shelf is numbered as 1, shelf Just above shelf 1 is numbered as 2 and so on till topmost shelf numbered as 6, but not necessarily in the same order. Stack A is in the west of Stack B whereas box 2 of stack A is immediately above box 1 of stack A and box 2 of stack B is immediately above box 1 of stack B and so on. Each box is of different heights ranging between 60cm and 100cm where the total height of both the stacks is the same which is 462cm.

Note: No two boxes have the same height. If a box in stack A is odd-numbered in height, then the box to its immediate right has definitely lesser height than that box. Box W is placed on the same stack immediately above box Q which is not adjacent to box O. The box which is two boxes below box Q on the same stack is 71cm. Box S is 92cm and is placed on an even-numbered shelf. The box which is placed to the immediate left of box Q is 3cm taller than box Q. One of the boxes on shelf 3 is 77cm which is 4cm taller than box R. Box Y is 10cm shorter than box R. Box X is taller than box P which is not 71cm. Box Y is three boxes below the box with 76cm in height where both the boxes are placed on the same stack but neither at the top nor at the bottom shelf. The box which is on a different stack and two boxes below the box with 76cm height is immediately below box Z which is 86cm in height. Box Z and box Y were placed in different stacks. No box is to the immediate right and immediately below box V which is 70cm in height. Box T is placed immediately above box V but in different stack and is 5cm shorter than box V. Box O is placed immediately above box T but on different stacks. More than three shelves are there between the boxes R and U where both are placed on the same stack. The box which is 20cm taller than box V is placed to the immediate right of box U which is 4cm shorter than box Z.
