1. Direction: Study the following information carefully and answer the questions that follow:

Nine people Harshada, Kalyani, Deepika, Sneha, Rutuja, Utkarsha, Sayli, Mohini and Anshika live in a building with nine floors but not necessarily in the same order. The lowermost building floor is numbered 1, the floor above it 2 and so on till the topmost floor is numbered 9.

Anshika lives on a floor which is three floors below the floor on which Harshada lives. The number of people living between Mohini and Utkarsha is the same as a number of people living between Rutuja and Utkarsha. Sneha lives on floor no 3. There are as many floors above Sneha’s floor as many floors are below Deepika’s floor. Rutuja lives on the floor below the floor on which Kalyani lives and 6 people are living between them. As many floors are above as are below the floor on which Utkarsha lives. Harshada does not live on the 6^th floor.

6. Directions: Read the following information carefully to answer the given questions.

Eight people A, B, C, D, E, F, G and H are living in a four-storey building such that ground floor is numbered as 1, above it is floor 2, and then top floor is numbered 4. Each of the floors has two flats in it as flat P and flat Q. Flat P of floor 2 is immediately above the flat P of floor 1 and immediately below the flat P of floor 3 and so on. In the same way, flat Q of floor 2 is immediately above the flat Q of floor 1 and immediately below the flat Q of floor 3 and so on. Flat P is in the west of flat Q.

There is a gap of a floor between the floors where A and H lives. B lives on an odd-numbered floor but not on the same floor of D. G and F neither live in the same flat nor on the same floor. F, who lives on an odd-numbered floor, lives immediately below C in the same flat. D lives below F in the same flat as that of G. D does not live on the second floor. E lives immediately below A in flat P.

Question:

Who among the following lives on the same floor as that of G?

D
C
E
A
None of these

Solution

People: A, B, C, D, E, F, G and H

Floor: 1 to 4, each having flat P and Q.

(1) F, who lives on an odd-numbered floor, lives immediately below C in the same flat.

(2) D lives below F in the same flat as that of G.

(3) D does not live on the second floor.

(4) G and F neither live in the same flat nor on the same floor.

Case 2

Floor	Flat P	Flat Q
4		C
3	B	F
2
1	D

(6) There is a gap of a floor between the floors where A and H lives.

(7) E lives immediately below A in flat P, here case 2 eliminates.

Therefore the final arrangement is

Floor	Flat P	Flat Q
4	C	H
3	F	B
2	A	G
1	E	D

Hence, A lives on the same floor as that of G.

7. Directions: Read the following information carefully to answer the given questions.

Question:

How many floors is/are there between the floors where B and E lives?

One
Two
Three
Four
None

Solution

People: A, B, C, D, E, F, G and H

Floor: 1 to 4, each having flat P and Q.

(1) F, who lives on an odd-numbered floor, lives immediately below C in the same flat.

(2) D lives below F in the same flat as that of G.

(3) D does not live on the second floor.

(4) G and F neither live in the same flat nor on the same floor.

Case 2

Floor	Flat P	Flat Q
4		C
3	B	F
2
1	D

(6) There is a gap of a floor between the floors where A and H lives.

(7) E lives immediately below A in flat P, here case 2 eliminates.

Therefore the final arrangement is

Floor	Flat P	Flat Q
4	C	H
3	F	B
2	A	G
1	E	D

Hence, there is one between the floors where B and E lives.

8. Directions: Read the following information carefully to answer the given questions.

Question:

Four of the following five are alike in a certain way and hence form a group. Which is the one that does not belong to the group.

C, A
B, G
F, A
H, A
H, D

Solution

People: A, B, C, D, E, F, G and H

Floor: 1 to 4, each having flat P and Q.

(1) F, who lives on an odd-numbered floor, lives immediately below C in the same flat.

(2) D lives below F in the same flat as that of G.

(3) D does not live on the second floor.

(4) G and F neither live in the same flat nor on the same floor.

Case 2

Floor	Flat P	Flat Q
4		C
3	B	F
2
1	D

(6) There is a gap of a floor between the floors where A and H lives.

(7) E lives immediately below A in flat P, here case 2 eliminates.

Therefore the final arrangement is

Floor	Flat P	Flat Q
4	C	H
3	F	B
2	A	G
1	E	D

We can see that in all the options both people live in the same flat except H, A.

Hence, H, A is the one that does not belong to the group.

9. Directions: Read the following information carefully to answer the given questions.

Question:

Which of the following statement is not true?

E lives on first floor.
F and D do not live on the same floor.
A and G live in the same flat name.
G and H live on the even-numbered floors.
None of these

Solution

People: A, B, C, D, E, F, G and H

Floor: 1 to 4, each having flat P and Q.

(1) F, who lives on an odd-numbered floor, lives immediately below C in the same flat.

(2) D lives below F in the same flat as that of G.

(3) D does not live on the second floor.

(4) G and F neither live in the same flat nor on the same floor.

Case 1

Floor	Flat P	Flat Q

Case 2

Floor	Flat P	Flat Q
4		C
3		F

Floor	Flat P	Flat Q
4	C
3	F	B
2
1		D

Case 2

Floor	Flat P	Flat Q
4		C
3	B	F
2
1	D

(6) There is a gap of a floor between the floors where A and H lives.

(7) E lives immediately below A in flat P, here case 2 eliminates.

Therefore the final arrangement is

Floor	Flat P	Flat Q
4	C	H
3	F	B
2	A	G
1	E	D

We can see that in all the statements are true except 'A and G live in the same flat name' as A lives in flat P and G in flat Q.

Hence, A and G live in the same flat name is not true.

10. Directions: Read the following information carefully to answer the given questions.

Question:

If F and G interchange their position with each other, who lives immediately above G?

A
C
B
H
Can't be determined

Solution

People: A, B, C, D, E, F, G and H

Floor: 1 to 4, each having flat P and Q.

(1) F, who lives on an odd-numbered floor, lives immediately below C in the same flat.

(2) D lives below F in the same flat as that of G.

(3) D does not live on the second floor.

(4) G and F neither live in the same flat nor on the same floor.

Case 1

Floor	Flat P	Flat Q
4	C
3	F
2
1		D

Case 2

Floor	Flat P	Flat Q
4		C
3		F
2

(5) B lives on an odd-numbered floor but not on the same floor of D.

Case 1

Floor	Flat P	Flat Q
4	C
3	F	B
2
1		D

Case 2

Floor	Flat P	Flat Q
4		C
3	B	F
2
1	D

(6) There is a gap of a floor between the floors where A and H lives.

(7) E lives immediately below A in flat P, here case 2 eliminates.

Therefore the final arrangement is

Floor	Flat P	Flat Q
4	C	H
3	F	B
2	A	G
1	E	D

If F and G interchange their position with each other.

Floor	Flat P	Flat Q
4	C	H
3	G	B
2	A	F
1	E	D

We can see that in all the C lives immediately above G.

Hence, C lives immediately above G.
