Directions:
Study the following information carefully and answer the questions given below :
In a building there are thirteen flats on three floors— II, III and IV. Five flats are unoccupied. Three managers, two teachers, two lawyers and one doctor occupy the remaining flats. There are at least three flats on any floor and not more than six flats on any floor. No two persons of the same profession stay on any floor. On the second floor, out of four flats, one occupant is the lawyer and has only one neighhour. One teacher lives one floor below the other teacher. The doctor is not the neighbour of any of the lawyers. No flat is unoccupied on the third floor
Question : 2
How many flats are there on the third floor?
a) Four
b) Five
c) Three or Four
d) Three
Answer »Answer: (d)
Total Number of flats = 13; Unoccupied flats = 5
Occupied flats = 8
Number of flats on second floor = 4
Second floor comprises four flats. One occupant is lawyer and since he has only one neighbour, this implies that out of four flats on second floor, two are unoccupied.
Again, since no flat is unoccupied on the third floor, it implies that there are three unoccupied flats on floor IV.
Since there are at least three flats on any floor and no two same profession stay on any floor and the doctor is not the neighbour of any lawyer, then floor III comprises only three flats. Thus, floor IV comprises six flats (3 occupied + 3 unoccupied).
Since there are three managers and no two same profession stay on any floor, therefore, there will be a manager in each floor. Also there are only two occupant in second floor and one of them is lawyer, therefore, second occupant should be manager.
Again, since there are two teachers, there will be a teacher each on floors III and IV. Again, doctor can't be neighbour of a lawyer. Hence, the doctor and lawyer will not reside on same floor. Therefore, on floor III – either Doctor or Lawyer then,
on floor IV – either Lawyer or Doctor.
| Floor | Total Flats | Occupied flats | Unoccupied flats | Occupants |
| II | 4 | 2 | 2 | Lawyer, Manager |
| III | 3 | 3 | 0 | Teacher, Manager, Lawyer or Doctor |
| IV | 6 | 3 | 3 | Teacher, Manager, Doctor or Lawyer |
Clearly, there are three flats.

c) Two
d) Data inadequate
Answer »Answer: (a)
Total Number of flats = 13; Unoccupied flats = 5
Occupied flats = 8
Number of flats on second floor = 4
Second floor comprises four flats. One occupant is lawyer and since he has only one neighbour, this implies that out of four flats on second floor, two are unoccupied.
Again, since no flat is unoccupied on the third floor, it implies that there are three unoccupied flats on floor IV.
Since there are at least three flats on any floor and no two same profession stay on any floor and the doctor is not the neighbour of any lawyer, then floor III comprises only three flats. Thus, floor IV comprises six flats (3 occupied + 3 unoccupied).
Since there are three managers and no two same profession stay on any floor, therefore, there will be a manager in each floor. Also there are only two occupant in second floor and one of them is lawyer, therefore, second occupant should be manager.
Again, since there are two teachers, there will be a teacher each on floors III and IV. Again, doctor can't be neighbour of a lawyer. Hence, the doctor and lawyer will not reside on same floor. Therefore, on floor III – either Doctor or Lawyer then,
on floor IV – either Lawyer or Doctor.
| Floor | Total Flats | Occupied flats | Unoccupied flats | Occupants |
| II | 4 | 2 | 2 | Lawyer, Manager |
| III | 3 | 3 | 0 | Teacher, Manager, Lawyer or Doctor |
| IV | 6 | 3 | 3 | Teacher, Manager, Doctor or Lawyer |

Since there are at least three flats on any floor and no two same profession stay on any floor and the doctor is not the neighbour of any lawyer, then floor III comprises only three flats. Thus, floor IV comprises six flats (3 occupied + 3 unoccupied).
Since there are three managers and no two same profession stay on any floor, therefore, there will be a manager in each floor. Also there are only two occupant in second floor and one of them is lawyer, therefore, second occupant should be manager.
Again, since there are two teachers, there will be a teacher each on floors III and IV. Again, doctor can't be neighbour of a lawyer. Hence, the doctor and lawyer will not reside on same floor. Therefore, on floor III – either Doctor or Lawyer then,
on floor IV – either Lawyer or Doctor.
| Floor | Total Flats | Occupied flats | Unoccupied flats | Occupants |
| II | 4 | 2 | 2 | Lawyer, Manager |
| III | 3 | 3 | 0 | Teacher, Manager, Lawyer or Doctor |
| IV | 6 | 3 | 3 | Teacher, Manager, Doctor or Lawyer |

Since there are at least three flats on any floor and no two same profession stay on any floor and the doctor is not the neighbour of any lawyer, then floor III comprises only three flats. Thus, floor IV comprises six flats (3 occupied + 3 unoccupied).
Since there are three managers and no two same profession stay on any floor, therefore, there will be a manager in each floor. Also there are only two occupant in second floor and one of them is lawyer, therefore, second occupant should be manager.
Again, since there are two teachers, there will be a teacher each on floors III and IV. Again, doctor can't be neighbour of a lawyer. Hence, the doctor and lawyer will not reside on same floor. Therefore, on floor III – either Doctor or Lawyer then,
on floor IV – either Lawyer or Doctor.
| Floor | Total Flats | Occupied flats | Unoccupied flats | Occupants |
| II | 4 | 2 | 2 | Lawyer, Manager |
| III | 3 | 3 | 0 | Teacher, Manager, Lawyer or Doctor |
