1) Eight friends Q, T, J, H, W, L, S, Z lives in a multi storey building such that topmost floor is numbered 1 and ground floor is numbered 8.

2) Z lives on an odd numbered floor but lives above floor numbered 4. From this we can say that Z lives on floor numbered 7. Z does not live on 5th floor.

3) Two people live between Z and J, who lives just above S.

4) Number of floors below Z is same as number of floors above L. So, from this we can say that L lives on floor numbered 2nd.

5) Q lives below J. After arranging the only position we can position Q is at floor numbered 1.

6) Both H and W do not live on the topmost floor. Hence, T lives on the topmost floor.

7) H lives on an even-numbered floor. Hence H lives on floor number 6. And W lives on floor number 5.

So our final arrangement is,

1) Eight friends Q, T, J, H, W, L, S, Z lives in a multi storey building such that topmost floor is numbered 1 and ground floor is numbered 8.

2) Z lives on an odd numbered floor but lives above floor numbered 4. From this we can say that Z lives on floor numbered 7. Z does not live on 5th floor.

3) Two people live between Z and J, who lives just above S.

4) Number of floors below Z is same as number of floors above L. So, from this we can say that L lives on floor numbered 2nd.

5) Q lives below J. After arranging the only position we can position Q is at floor numbered 1.

6) Both H and W does not live on the topmost floor. Hence, T lives on topmost floor.

7) H lives on an even numbered floor. Hence H lives on floor numbered 6. And W lives on floor numbered 5.

So our final arrangement is,

From the above arrangement, “4” people lives between L and Z.

1) Eight friends Q, T, J, H, W, L, S, Z lives in a multi storey building such that topmost floor is numbered 1 and ground floor is numbered 8.

2) Z lives on an odd numbered floor but lives above floor numbered 4. From this we can say that Z lives on floor numbered 7. Z does not live on 5th floor.

3) Two people live between Z and J, who lives just above S.

4) Number of floors below Z is same as number of floors above L. So, from this we can say that L lives on floor numbered 2nd.

5) Q lives below J. After arranging the only position we can position Q is at floor numbered 1.

6) Both H and W does not live on the topmost floor. Hence, T lives on topmost floor.

7) H lives on an even numbered floor. Hence H lives on floor numbered 6. And W lives on floor numbered 5.

So our final arrangement is,

From the above arrangement, “Q” lives on floor numbered 1.

1. E lives on the third floor.

2. E is 2 floors above D.

3. The floors between B and C are equal to those between D and B, one of them being at an extreme.

4. G doesn’t live on an even floor.

Therefore, G lives on the fifth floor.

5. Floor number of H is a multiple of that of B.

6. There is one floor between H and A.

1. E lives on the third floor.

2. E is 2 floors above D.

3. The floors between B and C are equal to those between D and B, one of them being at an extreme.

4. G doesn’t live on an even floor.

Therefore, G lives on the fifth floor.

5. Floor number of H is a multiple of that of B.

6. There is one floor between H and A.

Hence, A lives on the 6^th floor

1. E lives on the third floor.

2. E is 2 floors above D.

3. The floors between B and C are equal to those between D and B, one of them being at an extreme.

4. G doesn’t live on an even floor.

Therefore, G lives on the fifth floor.

5. Floor number of H is a multiple of that of B.

6. There is one floor between H and A.

The floor numbers of B and H are 4 and 8 respectively whose sum is 12.

1) F stays on 6^th floor.

2) H stays on the topmost floor.

3) D stays on 1^st floor.

4) 3 persons stay between A and D. As D stays on the 1^st floor, A stays on the 5^th floor.

5) C is not an immediate neighbour of A. So, C cannot reside on the 4^th floor.

If C stays on 7^th floor, then statement E stays between B and C (B E C) doesn’t satisfy and as C cannot stay on the 4^th floor, we place C on the 2^nd floor.

So, now B resides on the 4^th floor and E on the 3^rd floor.

Now, G can be placed on the 7^th floor.

If E Stays between B and C, then B and C stay on 4^th and 2^nd floor respectively.

1) F stays on 6^th floor.

2) H stays on the topmost floor.

3) D stays on 1^st floor.

4) 3 persons stay between A and D. As D stays on the 1^st floor, A stays on the 5^th floor.

5) C is not an immediate neighbour of A. So, C cannot reside on the 4^th floor.

If C stays on 7^th floor then statement E stays between B and C (B E C) doesn’t satisfy and as C cannot stay on the 4^th floor, we place C on the 2^nd floor.

So, now B resides on the 4^th floor and E on the 3^rd floor.

Now, G can be placed on the 7^th floor.

Hence, statement B stays in between A and E is true.

1) F stays on 6^th floor.

2) H stays on the topmost floor.

3) D stays on 1^st floor.

4) 3 persons stay between A and D. As D stays on the 1^st floor, A stays on the 5^th floor.

5) C is not an immediate neighbour of A. So, C cannot reside on the 4^th floor.

If C stays on 7^th floor then statement E stays between B and C (B E C) doesn’t satisfy and as C cannot stay on the 4^th floor, we place C on the 2^nd floor.

So, now B resides on the 4^th floor and E on the 3^rd floor.

Now, G can be placed on the 7^th floor.

Hence, G stays on the 7^th floor.

1) Only three persons live below the floor on which T lives.

2) Two people live between the floor on which T and W live.

3) The number of people living above Q is the same as the number of people living below W.

4) More than three people live between P and R.

5) P lives on an odd number floor but not on the lowest floor.

6) Three people live between S and V. (This eliminates case 2)

7) S lives above V.

1) Only three persons live below the floor on which T lives.

2) Two people live between the floor on which T and W live.

3) The number of people living above Q is the same as the number of people living below W.

4) More than three people live between P and R.

5) P lives on an odd number floor but not on the lowest floor.

6) Three people live between S and V. (This eliminates case 2)

7) S lives above V.

Hence, no one lives between W and U.

1) Only three persons live below the floor on which T lives.

2) Two people live between the floor on which T and W live.

3) The number of people living above Q is the same as the number of people living below W.

4) More than three people live between P and R.

5) P lives on an odd number floor but not on the lowest floor.

6) Three people live between S and V. (This eliminates case 2)

7) S lives above V.

Hence, ‘V’ lives just below ‘Q’

People: P, Q, R, S, T, and U
Floors: 1 – 6

1. Q lives on an even numbered floor ⇒ This gives us 3 possibilities:

2. Only two people live between the floors on which Q and U live.

3. S does not live on an odd numbered floor. ⇒ S lives on an even numbered floor.
4. S lives on a floor immediately above the floor on which R lives.

5. P does not live on a floor which is immediately above or immediately below the floor on which T lives.

6. P does not live on the lowermost floor i.e. floor no. 1. ⇒ In all other possibilities but 3^rd, P and T will be neighbors. Hence, only possibility 3^rd is feasible.
∵ P doesn’t live on the 1^st floor so he lives on the 6^th floor.

Clearly, R and S live on the floors between Q and U.

People: P, Q, R, S, T, and U
Floors: 1 – 6

1. Q lives on an even numbered floor ⇒ This gives us 3 possibilities:

2. Only two people live between the floors on which Q and U live.

3. S does not live on an odd numbered floor. ⇒ S lives on an even numbered floor.
4. S lives on a floor immediately above the floor on which R lives.

5. P does not live on a floor which is immediately above or immediately below the floor on which T lives. 

6. P does not live on the lowermost floor i.e. floor no. 1. ⇒ In all other possibilities but 3rd P and T will be neighbors. Hence, only possibility 3rd is feasible.
∵ P doesn’t live on the 1st floor so he lives on the 6th floor.

Clearly, U lives on floor number 5.

People: P, Q, R, S, T, and U
Floors: 1 – 6

1. Q lives on an even numbered floor ⇒ This gives us 3 possibilities:

2. Only two people live between the floors on which Q and U live.

3. S does not live on an odd numbered floor. ⇒ S lives on an even numbered floor.
4. S lives on a floor immediately above the floor on which R lives.

5. P does not live on a floor which is immediately above or immediately below the floor on which T lives. 

6. P does not live on the lowermost floor i.e. floor no. 1. ⇒ In all other possibilities but 3rd P and T will be neighbours. Hence, only possibility 3rd is feasible.
∵ P doesn’t live on 1st floor so he lives on 6th floor.

Clearly, T lives on the 1^st floor.
