DirectionsÂ (1 â€“ 5):

1. Z lives on the top floor.
2. U is in the middle of the North facing peopleâ€™s row.
3. V lives on the 3rdfloor.

4. There are exactly three floors between Z and X.

5. W and T sit at the extreme ends of the row and face south.

6. R sits to the left of W. This is not possible in Case II, therefore, Case II will be eliminated.

7. Y and R sit opposite to each other.

8. The person living on the 5thfloor (i.e. X) sits opposite to W and faces north.

9. Y lives above Râ€™s floor

10. Y does not live on 8thor 7thfloor. Y cannot be on 6thÂ or 4thÂ floor also as R lives immediately below Y.

(so, Y lives on 2ndÂ floor and R on 1stÂ floor)

11. S sits third to the right of Y.

12. S does not sit adjacent to vacant place. (Therefore, vacant place is in the south facing row.)

13. V faces south.

14. Z faces the vacant place.

15. The persons at the extreme ends of the north facing row are immediately next to each otherâ€™s floor (i.e. X and S).

16. V is not immediately next to Sâ€™s floor.

17. W and T are immediately next to each otherâ€™s floor.

Directions (6 â€“ 10):

1) R’s father visited the family doctor in April.

2) R’s brother visited the family doctor just after C.

3) C and J visited the family doctor at a gap of 3 persons.

4) J was not the first to visit the family doctor.

As Râ€™s father visited the doctor in April so we can surely say that the fatherâ€™s visit to the doctor was on 23rd April. Also it is given that Râ€™s brother visited the doctor just after C that means C must be a female member of the family.

After this the above hints can be used in two possible scenarios.

Case 1:

Case 2:

5) A visited the family doctor after a gap of 1 person from R’s sister’s visit to the doctor.

6) R’s son visited the family doctor just before R’s daughter’s visit to the doctor.

Here, we can use the first hint easily but the there are two possible scenarios in which second hint can be used in case 2.

Case 1:

Case 2:

Case 2-A:

7) R’s mother visited the family doctor either in August or October.

Here, we can use the first hint easily but the there are two possible scenarios in which second hint can be used in case 2.

Case 1:

Case 2-A:

Case 2-B:

8) R and B visited the family doctor in consecutive months but not on consecutive turns.

Here, we can use the first hint easily but the there are two possible scenarios in which second hint can be used in case 2.

Case 1:

Case 2-A(i):

Case 2-A(ii):

Case 2-A(iii):

Case 2-B(i):

Case 2-B(ii):

9) Number of persons who visited the family doctor after D was twice as that of the number of persons who visited the family doctor before M.Â  Neither of them was the last to visit the family doctor.

10) E was either the brother or father of R.

At this point, we cannot use the above hints in Case 1, Case 2-A(i), Case 2-A(iii) and Â Case 2-B(i) accordingly so we can say thatÂ Case 1, Case 2-A(i), Case 2-A(iii) and Â Case 2-B(i) are invalid cases.

Case 2-A(ii):

Case 2-B(ii):

11) E was either the brother or father of R.

Here, our case 2-B(ii) is contradicting with the above hints so we can say thatÂ case 2-B(ii) is an invalid case.

Now, case 2-A(ii) can be redrawn as:

Case 2-A(ii):

Here, we can also draw a blood chart of these persons.
