Direction: Study the following information carefully to answer the given questions.

Eight boxes – M, N, O, P, W, X, Y and Z – are placed in two stacks – Stack-A, and Stack-B, from West to East in such a way that there is equal number of boxes in each stack. Each stack has four shelves in such a way that the lowermost shelf is numbered as 1; the shelf immediately above the lowermost shelf is numbered 2 and so on. No shelf is vacant. Each box contains a different subject book among - Reasoning, Quant, English, Math, Physics, Chemistry, Hindi and Telugu – but not necessarily in the same order.  

Note: If it mentioned ‘above’ and ‘below’ then it means both boxes are placed in the same stack. For example, if it is given that box A is placed below box B, then it means boxes A and B are placed in the same stack.  

In the same stack, Two boxes are placed between box X and Physics book, which is placed immediately below box P.  Quant book and English book are placed immediately below and immediately above box W, but not necessarily in the same order. Neither the Quant book nor the English book is placed on the same shelf number as shelf number of Physics book is placed. Boxes W and P are placed in different stacks. Box O is placed immediately below the Math book. Boxes O and Z are in the same stack.

Reasoning book is placed immediately above box Z but not in stack B. Chemistry book and Telugu book are placed on the same shelf number but the Chemistry book and box English are not placed in the same stack. The number of boxes above the shelf in which box M is placed is equal to the number of boxes placed below the shelf in which box N is placed. Math book and box Y are not placed in the same shelf number. Box M does not have either English book or Hindi book.
