Seven people, C, D, E, F, L, M and N, are sitting in a row, facing north.
Only two people sit to the right of C. Only two people sit between C and L. Only two people sit between E and N. N sits to the immediate left of C. M sits to the immediate right of F. Who sits at the third position from the left end of the row?
Arrangement Puzzle: Deductive Reasoning
This problem involves a seating arrangement puzzle where seven people are sitting in a row facing north. We need to determine who occupies the third position from the left end based on the given clues.
Step-by-Step Deductions
Let's break down the clues to determine the exact seating positions:
- Clue 1: "Only two people sit to the right of C." Since there are 7 positions in total (1 to 7 from left to right), this means C must be in the 5th position.Positions: _ _ _ _ C _ _
- Clue 2: "N sits to the immediate left of C." As C is in position 5, N must be in position 4.Positions: _ _ _ N C _ _
- Clue 3: "Only two people sit between C and L." With C in position 5, L can either be in position 2 (Positions: _ L _ N C _ _) or position 8 (which is impossible). Therefore, L is in position 2.Positions: _ L _ N C _ _
- Clue 4: "Only two people sit between E and N." N is in position 4. If E sits to the left of N, there must be two people between them. This places E in position 1 (with L and D in between). If E sits to the right of N, there would be C and another person (F or M) between them, placing E in position 7. Let's analyze the first case: E in position 1.Positions: E L _ N C _ _
- Clue 5: "M sits to the immediate right of F." This means F and M are seated together as a pair (FM).
Final Arrangement
Based on the deductions so far, the arrangement looks like: E L _ N C _ _. The remaining positions are 3, 6, and 7. The remaining people are D, F, and M. We need to place the FM pair.
- The only adjacent empty slots are positions 6 and 7. So, F must be in position 6, and M must be in position 7.Positions: E L _ N C F M
- The only person left is D, and the only position left is 3.Positions: E L D N C F M
Let's verify all the clues with this final arrangement:
- Seven people (E, L, D, N, C, F, M) are in a row facing north. (Correct)
- Only two people (F, M) sit to the right of C. (Correct - C is 5th)
- Only two people (D, N) sit between C (5th) and L (2nd). (Correct)
- Only two people (L, D) sit between E (1st) and N (4th). (Correct)
- N (4th) sits to the immediate left of C (5th). (Correct)
- M (7th) sits to the immediate right of F (6th). (Correct)
The final seating arrangement from left to right is: E, L, D, N, C, F, M.
Identifying the Person at the Third Position
We need to find who sits at the third position from the left end.
Counting from the left:
- 1st position: E
- 2nd position: L
- 3rd position: D
- 4th position: N
- 5th position: C
- 6th position: F
- 7th position: M
Therefore, D sits at the third position from the left end of the row.
Important Questions from Seating Arrangement (Notes)
Read the directions carefully and give the answer from the given options.
P, Q, R, S, T, K, L, M and N are sitting around a circle facing the centre.
K is $4^{th}$ to the right of P and P is $3^{rd}$ to the right of Q.
N is $4^{th}$ to the left of Q and $3^{rd}$ to the right of S.
R is $2^{nd}$ to the right of M and M is the immediate neighbour of P.
T is $2^{nd}$ to the left of L.
Who is to the immediate left of K?
Seven people, F, J, M, L, R, V and X, are sitting in a row, facing north.
Only three people sit to the left of X. Only M sits to the right of R. Only three people sit between R and V. J sits at some place to the left of L but at some place to the right of F.
How many people sit to the left of V?Seven boxes, A, B, C, D, E, F and G, are kept one over the other but not necessarily in the same order. Only A is kept above F. Only D is kept between F and C. Only E is kept below B. How many boxes are kept below C?
P, Q, R, S, T, U and V are sitting in a row, facing north. No one sits to the left of U. Only four people sit between U and R. Only three people sit to the right of V. P sits to the immediate left of S. Q is not an immediate neighbour of V. How many people sit between P and T?
Six people, B, C, D, I, J and K, are sitting around a circular table facing the centre. Only two people sit between B and I when counted from the right of I. K sits to the immediate left of J. I sits to the immediate right of C. Who among the following are the immediate neighbours of D?
