# Example-1

Direction

Nine cricket fans are watching a match in a stadium. Seated in one row, they are J, K, L, M, N, O, P, Q and R. L is at the right of M and at third place at the right of N. K is at the one end of the row. Q is seated adjacent to both O and P. O is at the third place at the left of K. J is right next to left of O.

Example-1

Who is sitting at the centre of the row?

1. I
2. J
3. O
4. Q
5. L

Example-2

Who is at the other end of the row?

1. J
2. N
3. P
4. R
5. None of These

Example-3

Which of the following statements is true?

1. N is two seats away from J.
2. m is at one extreme end.
3. R and P are neighbours.
4. There is one person between L and O.
5. R sits second to the right of L.

Solution:

L is at the right of m and at third place at the right of n. so, the sequence becomes: N_ ML. O is at third place at the left of K and J is right next to left of O i.e. JO_ _ K. Q is adjacent to both O and p i.e. JOQPK. Thus, the only black space left must be occupied by R i.e. NRML. Since K is at one end of the row, so the entire seating sequence becomes: NRMLJOQPK.
1. J is sitting at the centre of the row. So, the answer is (b).
2. N is at the other end of the row. So, the answer is (b).
3. Clearly, there is one persons J between L and O. so, only (d) is true. Hence, the answer is (d).

# Example-2

Direction

1. A, B, C, D, E, F and G are sitting around a circle and are facing the centre.
2. G is second to the left of C who is to the immediate left of F.
3. A is third to the left of E.
4. B is between D and E.

Example-1

Which of the following is false?

1. A is fourth to the right of E.
2. G is to the immediate right of D.
3. F is third to the right of D.
4. B is to the immediate left of D.
5. None of these

Example-2

Which of the following is true?

1. C is fourth to the left of B.
2. A is to the immediate right of G.
3. D is second to the left of E.
4. B is second to the right of G.
5. None of these

Example-3

Which of the following pairs has the first person sitting to the immediate left of the second person?

1. BE
2. CA
3. GD
4. DG
5. None of these

Example-4

Which of the following has the middle person sitting between the remaining two?

1. FCE
2. EFB
3. DEB
4. GDA
5. None of these

Example-5

Which of the following is the position of F?

1. Fourth to the right of D
2. To the immediate left of C
3. Between A and E
4. To the immediate right of A
5. None of these

Solution:

We first of all mark the seven blank positions around a circle. Now, G is second to the left of C and C is to the immediate left of F. We mark their positions as shown. Also, B is between D and E. Thus, D, B, E sit together and occupy the three consecutive blank positions. Now, only one position remains blank between G and C, and this must be occupied by A. Now, D, B, E may sit in any of the positions (D, B, E) or (E, B, D). But A is third to the left of E only when they sit in the order (D, B, E)..

1. Clearly, F is fourth to the right of D. so, (c) is false. Hence, the answer is (c).
2. C is third to the left of B. So, (a) is false. A is to the immediate right of G. So, (b) is true. D is second to the right of E. So, (c) is false. B is second to the left of G. So, (d) is false. Hence, the answer is (b).
3. Clearly, only in the pair DG, the first person D sits to the immediate left to the second person G. hence, the answer is (d).
4. C sits between A and F; F sits between E and C; E sits between B and F; D sits between G and b. So, none of the given groups satisfies the given condition.
5. Clearly, Fâ€™s position is (i) fourth to the right of D (ii) to the immediate right of C (iii) between C and E (iv) second to the right of A. Hence, the answer is (a).
