Here, persons K, L, M, N, O, P, Q and R.

1. Three persons live between O and P.

2. O lives on an odd number floor below the fifth floor.

3. One person lives between M and L who lives above M.

4. K lives immediately above R.

5. R lives above Q but below M.

6. N and Q lives on an adjacent floor. Therefore, case 2 is eliminated.

7. N does not live just below O. Hence, the final arrangement is as follows

Hence, O lives three floors below the floor of M.

Here, persons K, L, M, N, O, P, Q and R.

1. Three persons live between O and P.

2. O lives on an odd number floor below the fifth floor.

3. One person lives between M and L who lives above M.

4. K lives immediately above R.

5. R lives above Q but below M.

6. N and Q lives on an adjacent floor. Therefore, case 2 is eliminated.

7. N does not live just below O. Hence, the final arrangement is as follows

Since, one person lives below the floor of Q and one person lives above the floor of P.

Hence, the correct answer is P.

Here, persons K, L, M, N, O, P, Q and R.

1. Three persons live between O and P.

2. O lives on an odd number floor below the fifth floor.

3. One person lives between M and L who lives above M.

4. K lives immediately above R.

5. R lives above Q but below M.

6. N and Q lives on an adjacent floor. Therefore, case 2 is eliminated.

7. N does not live just below O. Hence, the final arrangement is as follows

Hence, M lives on sixth floor.

Here, persons K, L, M, N, O, P, Q and R.

1. Three persons live between O and P.

2. O lives on an odd number floor below the fifth floor.

3. One person lives between M and L who lives above M.

4. K lives immediately above R.

5. R lives above Q but below M.

6. N and Q lives on an adjacent floor. Therefore, case 2 is eliminated.

7. N does not live just below O. Hence, the final arrangement is as follows

Since, M lives just above the floor of K. Therefore, statement first is correct.

N lives on an odd number floor. Therefore, statement second is correct.

O lives below R. Therefore, statement third is correct.

Hence, the correct answer is all of these.

Here, persons K, L, M, N, O, P, Q and R.

1. Three persons live between O and P.

2. O lives on an odd number floor below the fifth floor.

3. One person lives between M and L who lives above M.

4. K lives immediately above R.

5. R lives above Q but below M.

6. N and Q lives on an adjacent floor. Therefore, case 2 is eliminated.

7. N does not live just below O. Hence, the final arrangement is as follows

Since, the position of M and Q remain the same.

Hence, the correct answer is two persons.

The least possible Venn diagram for the given statements is as follows:

Conclusion:

I. At least some horses are goats → False (As there is no relation between horses and goats so we cannot say whether some horses are goats or not)

II. All cows being camels is a possibility → False (As per the statement no goats is camels and all cows are goats, If we will take goats inside camels then the conditions of the statement will be violated)

Hence, Neither I nor II follows.

The least possible Venn diagram for the given statements is as follows:

Conclusion:

I. All stones are leaves is a possibility → True (As there is no definite relation between leaves and stones, If we will take stones inside leaves then no statement will be violated)

II. Some stones are not leaves → False (As there is no definite relation between leaves and stones but no negative statement is there so no negative conclusion will follow)

Hence, Only I follows​.

Additional information:

If there is no negative statement then no negative conclusion will follow.

The least possible Venn diagram for the given statements is as follows

Conclusion:

I. At least some cash are coins → False (Some cash cannot be coin as cash will make positive relation only with notes but it can make negative relation with any other element)

II. Some cash are liquid is a possibility → False (Cash will make positive relation only with notes)

Hence, Neither I nor II follows.

Additional Information

1. ‘Only A are B’ means that B can not be linked with any other object. 2. The term 'Atleast' can be used as 'Some'. 

If it is given that 'Atleast some A are B', it means some amount of A is definitely B, and there is also the possibility of all A being B.

Backward direction:- R - T

Hence, there is only one such pair.

1. D sits adjacent to R.

2. R has only one neighbour.

3. Only two persons sit between M and D. 

4. B sits third to the left of M. Therefore, case 1 is eliminated.

5. Four persons sit between Z and B.

6. Q sits two places away from O and adjacent to Z.

7. Three persons sit between O and F.

8. O sits second position from the end position. Therefore, case 2(a) is eliminated.

9. Not more than one person sits between Q and F. Hence, the final arrangement is as follows

Since, six persons sit between B and R.

Hence, the correct answer is more than four.
