Direction: Eight teachers are conducting one to one Quiz competition for the Class X students, for that all of them are seated around rectangular tables. The rectangular tables are such that one is small and second is large with small inside the larger one. The teachers J to Q are sitting around the outer rectangular table in such a way that 4 of them sit at the corner of the table and 4 of them sit in the middle of the table and all of them face towards the Centre. The students R to Y are sitting around the inner rectangular table in such a way that 4 of them sit at the corner of the table and 4 of them sit in the middle of the table and all of them face outwards the Centre. So in this way, each teacher is facing his/her respective student for whom he/she is conducting quiz when they are sitting on the same sides of the table. The experience of all teachers ranges from 1 to 8 years and the registration number of all students ranges from 61 to 68. Teacher/Students with consecutive alphabetic names are not immediate neighbors in either of the tables i.e. B is not an immediate neighbor of A and C. All the above information is not necessarily in the same order. L sits adjacent to O, who has least experience among eight teachers. X sits second to the right of Y and his/her registration number is multiple of 11. Registration number of V and W are prime numbers but W's registration number is greater than that of V. Only one person sits between J and K, whose experience is divisible by 5. P doesn’t sit adjacent to J and his/her experience is half of L. Number of persons sitting between X and V is same as between V and W, who did not attended the quiz by the teacher, whose experience is 5 years. T’s registration number is a perfect square and sits diagonally opposite to the student, whose registration number is 63. The student who was attending the quiz by the teacher L sits fourth to the left of Y, whose registration number is 62. The student R, whose registration number is 65, does not not attend the quiz by the teacher P. The student V attends the quiz by the teacher who has four years of experience. S attends the quiz by the teacher, who has 1 year of experience. S’ registration number is divisible by 9. J’s experience is perfect cube and he/she doesn’t sit at the corner of the table. The experience of teachers N and Q are not a composite numbers but Q has less experience than N. M is not adjacent to K and only one person sits between M and N, whose experience is a prime number. Three persons sit between the one who has 8 years experience and L, who has half of the experience of J.
