Question

Accepted Answer

We have The one who likes 2 sits 5m from left end, since only such combinations are 2, 3, 1, 1, 3  1, 2, 2. Two person sits between the one who likes 2 and F, who likes 8 and sits facing north. F neither sits at end of the row nor sits adjacent to W, that means we have four possible cases, in case 1 the one who likes 2 sits 2  3a from left end, in case 2 the one who likes 2 sits 3  2a from left end, in case 3 the one who likes 2 sits 1  3  1a sits from left end, in case 4 the one who likes 2 sits 2  1  2a from left end. W sits 4m left of the one who likes 8 and is 1m right of the one who likes 5, since only possible such combination is 1, 4. The one who likes 5 sits three places away from A, who doesnt like odd number. A sits immediate right of the one who likes 6, thus in case 1a A sits at right end and the one who likes 5 sits fourth from right end, in case 1b A sits second from left end and the one who likes 5 sits fourth from right end, in case 2a A sits at right end and the one who likes 5 sits fourth from right end, in case 2b A sits second from left end and the one who likes 5 sits fourth from the right end, in case 3  case 4 A sits third from left end and the one who likes 5 sits third from right end. Based on above given information we have   Again, we have Z sits third to right of the one who likes 3, since none of the adjacent person likes consecutive numbers. Z neither sits adjacent to A nor likes even number, that means in case 1a, case 1b, case 2a  case 2b the one who likes 3 sits at right end facing south and case 3  case 4 are not valid. The one who likes 4 sits 2m away from X. X sits 7m left of the one who likes 7, thus in case 1a  case 1b X sits at left end and W likes 7, in case 2b X sits at right end and W sits facing south. Based on above given information we have Case-1a  Case 3  case 4 are not valid as Z sits third to right of the one who likes 3 and case 2a is not valid as X sits 7m left of the one who likes 7. Again, we have Y sits immediate right of the one who likes 1.  J sits 8m left of E, who neither likes prime number nor sits adjacent to the one who likes 4, that means in case 1a  case 1b J sits third from left end and E sits facing north, case 2b is not valid.  Z sits 6m right of Y, that means distance between E and Y is 1m and case 1a is not valid. Y and A sits facing in same direction but opposite to the direction of J, that means A sits facing south and J sits facing North. Based on above given information we have final arrangement as follow Case 2b is not valid as J sits 8m left of E and case 1a is not valid as Z sits 7m right of Y. Case-1b
