Circular Table Arrangement Logic
We need to arrange five friends (S, U, K, N, M) around a circular table facing the centre based on the given clues.
- Clue 1: K is the immediate neighbour of S and M. This means K sits exactly between S and M. The sequence must be S-K-M or M-K-S.
- Consider the S-K-M block: The remaining friends are U and N. The arrangement could be S-K-M-U-N or S-K-M-N-U in clockwise order.
- Clue 2: S is not the immediate neighbour of U.
- In the S-K-M-N-U arrangement, S's neighbours are K and U. This contradicts the clue.
- Therefore, the arrangement must be S-K-M-U-N (clockwise).
- Clue 3: N is not the immediate neighbour of M.
- In the S-K-M-U-N arrangement, M's neighbours are K and U. N's neighbours are U and S. M and N are not neighbours, satisfying the clue.
The final clockwise seating arrangement is S-K-M-U-N.
Identifying Neighbours of K and N
Based on the deduced arrangement S-K-M-U-N:
- The immediate neighbours of K are S and M.
- The immediate neighbours of N are U and S.
The question asks for the immediate neighbour of K and N. This implies finding the person who is a neighbour to both K and N.
Comparing the neighbours:
- K's neighbours: {S, M}
- N's neighbours: {U, S}
The common neighbour is S.
Important Questions from Seating arrangement
Five people A, B, C, D and E are seated about a round table. Every chair is spaced equidistant from adjacent chairs.
(i) C is seated next to A
(ii) A is seated two seats from D
(iii) B is not seated next to A
On the basis of above information, which of the following must be true?
1. D is seated next to B
2. E is seated next to A
3. D and C are separated by two seats
Select the correct answer using the code given below:
There are seven persons up on a ladder, A, B, C, D, E, F and G (not in that order). A is further up than E but is lower than C. B is in the middle. G is between A and B. E is between B and F. If F is between E and D, the person on the bottom step of the ladder will be
Consider that:
1. A is taller than B.
2. C is taller than A.
3. D is taller than C.
4. E is the tallest of all.
If they are made to sit in the above order of their height, who will occupy the mid position?
Four children are sitting in a row. A is occupying the seat next to B but not next to C. If C is not sitting next to D, who is/are occupying seat/seats adjacent to D?
A question paper must have a question on one of the eight poets: A, B, C, D, E, F, G or H The first four belong to the medieval period while the rest are considered modern poets Generally, modern poets figure in the question paper in alternate years. Generally those who like H like G also; and those who like F like E also. The paper-setter does not like to ask about F as he has written a book on F, but he likes F. Last year, the paper contained a question on A.
On the basis of the information given, this year's paper is most likely to contain a question on
