Weight of which of the following box is

Solution

We have:   Box N is kept fifth from top. Five boxes are kept between the box H and the box N, which is wrapped   with Blue paper, that means the box H is kept below the box N.  Box H is neither wrapped Pink or kept adjacent to box whose weight is 23kg and H is not 23 kg. The box whose weight is 12kg is kept adjacent to the box F. Two boxes are kept between the box H and the box F, that means we have 4 cases are possibility The box wrapped with Pink paper is kept four places above the box E, whose weight is 12kg, that means in case (2) the pink box is kept at a gap of one place above the box N, in case (3) the pink box is kept at a gap of one place above the box H and case (1) & case (4) are not valid. Based on above given information we have: Case (1) is not valid as the box wrapped with Pink paper is kept four places above the box E, whose weight is 12kg and case (4) is not valid as H doesn’t like Pink . Again, we have:  The Pink box is kept six places above the box Z, which is marked Black.  Three boxes are kept between the box whose weight is 23kg and the Black box, that means in case (2a) weight of the box N is 23kg, in case (2b) the box whose weight is 23kg is kept at a gap of one box below the box H, in case (3) the box whose weight is 23kg is kept below the box Z hence H is not 23 kg. Number of boxes between the box whose weight is 23kg and the box F is same as the number of boxes between Cream box and the box M, which is wrapped with Pink paper. The box wrapped with Cream box is neither kept at bottom nor kept adjacent to the Blue box, that means in case (2b) & case (3) box F wrapped with Cream box and case (2a) is not valid.  The box whose weight is 21kg is kept third from bottom.  The box whose weight is 12kg is marked Pink. The Pink box is kept exactly between the box whose weight is 21kg and the Orange box, whose weight is 18kg, that means in case (2b) & case (3) the box whose weight is 21kg is kept just above the box whose weight is 23kg Based on above given information we have: Case (2a) is not valid as number of boxes between the box whose weight is 23kg and the box F is same as the number of boxes between Cream box and the box M. Weight of the box Y is 21kg and is kept fourth place from the box the box whose weight is 8kg, and box have that means in case (2b) & case (3) weight of the box F is 8kg. The box whose weight is 21kg is kept third from bottom.  Number of boxes between the Blue box and the box T is twice the number of boxes between the box N and the box whose weight is 8kg, that means in case (2b) the box T is kept just above the box H and case (3) is not valid Weight of the box T is 11kg. Case (3) is not valid as number of boxes between the Blue box and the box T is twice the number of boxes between the box N and the box whose weight is 8kg.
