1) N is sitting at one end, and only two people are sitting between N and L.

2) Q is an immediate neighbor of one who is sitting at extreme end. No one is sitting between Q and M, who is sitting at extreme end

3) P is sitting to the immediate left of L and only two persons are sitting between P and O

4) R is an immediate neighbor of neither O nor Q

Hence, case 2 gets canceled.

So, the final arrangement will be

Hence, P is sitting second to the left of S.

1) N is sitting at one end, and only two people are sitting between N and L.

2) Q is an immediate neighbor of one who is sitting at extreme end. No one is sitting between Q and M, who is sitting at extreme end

3) P is sitting to the immediate left of L and only two persons are sitting between P and O

4) R is an immediate neighbor of neither O nor Q

Hence, case 2 gets canceled.

So, the final arrangement will be

Hence, Three people are sitting between R and O.

1) N is sitting at one end, and only two people are sitting between N and L.

2) Q is an immediate neighbor of one who is sitting at extreme end. No one is sitting between Q and M, who is sitting at extreme end

3) P is sitting to the immediate left of L and only two persons are sitting between P and O

4) R is an immediate neighbor of neither O nor Q

Hence, case 2 gets canceled.

So, the final arrangement will be

Hence, M is sitting fourth to the right of L.

1) N is sitting at one end, and only two people are sitting between N and L.

2) Q is an immediate neighbor of one who is sitting at extreme end. No one is sitting between Q and M, who is sitting at extreme end

3) P is sitting to the immediate left of L and only two persons are sitting between P and O

4) R is an immediate neighbor of neither O nor Q

Hence, case 2 gets canceled.

So, the final arrangement will be

Hence, O is sitting third to the right of P.

1) N is sitting at one end, and only two people are sitting between N and L.

2) Q is an immediate neighbor of one who is sitting at extreme end. No one is sitting between Q and M, who is sitting at extreme end

3) P is sitting to the immediate left of L and only two persons are sitting between P and O

4) R is an immediate neighbor of neither O nor Q

Hence, case 2 gets canceled.

So, the final arrangement will be

Immediate to the left of O → S

Second to the right of S → Q

Hence, Q is sitting second to the right of one, who is sitting immediate to the left of O.

Given statement,

E ≤ K > L > R = X > Q

Conclusions:

I. E > R → False (E ≤ K > L > R → a clear relation between E and R cannot be determined).

II. K > Q → True (K > L > R = X > Q → K > Q).

Hence, the correct answer is only conclusion II follows.

Given statements:  D ≥ S = J ≥ E; W > Y ≤ O; W > X > D;

After combining: O ≥ Y < W > X > D ≥ S = J ≥ E

Conclusions:

I. X > E  → True (as X > D ≥ S = J ≥ E)

II. W > D → True (as W > X > D)

Hence, Both conclusion I and II are true. 

Statement: H < B > U ≥ W = T ≥ Y > I < A ≥ Y

Conclusions:

I. B > I → True (B > U ≥ W = T ≥ Y > I → B > I)

II. A > W → False (W = T ≥ Y > I < A, no direct relationship between A and W can be determined).

Hence, Only Conclusion I follows.

Given Statement: H > K ≤ L = M < N < Q = S

Conclusions:

I. M < S → True (M < N ≤ Q = S → M < S)

II. Q < K → False (K ≤ L = M < N < Q → K < Q)

Hence, Only conclusion I follows.

Eight boxes namely H to O are placed in a rack one above the other.

1. Three boxes are between the box O and the box M but the box O is above the box M.

Here we have four cases according to this Condition.

2. Box L is immediate above the box N but below the box M.

(Case III and Case IV not follows because in the question given box L and box N are below the box M but it is not possible in these cases) 

Case I Splits into one more case i.e. Case I(a)

3. Four boxes are between the box L and the box J.

(Case I(a) and Case II not follows because in the question given Four boxes are between the box L and the box J but it is not possible in these cases)

4. Box K is above the box M and below the box J.

Again case I Splits into two more cases i.e. Case I and Case II 

5. Box I is below the box K and above the box L.

Again case II Splits into one more case i.e. case II(a)

6. Two boxes are between the box I and the box H.

(Case II and Case II(a) not follows because in the question given Two boxes are between the box I and the box H but it is not possible in these cases)

Hence, box L is between the box N and the box I.
