Question 1

Six people—A, B, C, D, E, and F—live in a building with 6 floors (1 to 6, where 1 is the ground floor). Each person lives on a different floor. Based on the following clues, who lives on Floor 3?

Clue 1: A lives on an odd-numbered floor.
Clue 2: B lives immediately above C.
Clue 3: D lives on Floor 5.
Clue 4: E lives on Floor 1.
Clue 5: F lives on an even-numbered floor, but not Floor 2.
Clue 6: C lives on Floor 3.

Accepted Answer

From Clue 6, C lives on Floor 3. This directly answers the question.

Question 2

Four people—M, N, O, and P—live on 4 different floors (1 to 4). Based on the clues below, who lives on Floor 4?

Clue 1: M does not live on Floor 1.
Clue 2: N lives on an even-numbered floor.
Clue 3: O lives on Floor 2.
Clue 4: P lives on a floor higher than O but lower than M.

Accepted Answer

From Clue 3, O is on Floor 2. From Clue 4, P is higher than O (Floor 2) but lower than M. So P must be on Floor 3, and M must be on Floor 4. This satisfies Clue 1 (M not on Floor 1) and Clue 4 (P on Floor 3 is between O on Floor 2 and M on Floor 4).

Question 3

Six people—Aman, Bhavna, Chirag, Diya, Eshan, and Fiona—live in a 6-floor building (floors 1–6, with 1 being the ground floor). Each person lives on a different floor. Based on the following clues, who lives on floor 3?

Clue 1: Aman lives on an even-numbered floor.
Clue 2: Bhavna lives immediately above Chirag.
Clue 3: Diya lives on floor 1.
Clue 4: Eshan lives on floor 5.
Clue 5: Fiona lives on a floor higher than Aman's floor.

Accepted Answer

From Clue 3, Diya is on floor 1. From Clue 4, Eshan is on floor 5. From Clue 1, Aman is on floor 2, 4, or 6. From Clue 2, Bhavna and Chirag are consecutive (Bhavna above). Remaining floors for assignment: 2, 3, 4, 6. If Aman is on floor 2, then Bhavna–Chirag must occupy two of {3, 4, 6}. If Bhavna–Chirag are on floors 3–4, Fiona is on floor 6 (satisfies Clue 5: 6 > 2). This leaves floor 3 for Bhavna. Verify: Diya(1), Aman(2), Bhavna(3), Chirag(4), Eshan(5), Fiona(6). All clues satisfied.

Question 4

Six items—W, X, Y, Z, P, Q—are placed on shelves 1–6 (one item per shelf). Using the clues, which item is on shelf 4?

Clue 1: Item W is on shelf 2.
Clue 2: Item X is on a shelf with a number greater than W's shelf number.
Clue 3: Item Y is on shelf 5.
Clue 4: Item Z is exactly 1 shelf below Item P.

Accepted Answer

From Clue 1, W is on shelf 2. From Clue 3, Y is on shelf 5. From Clue 2, X > 2, so X ∈ {3,4,5,6}. Since Y = 5, X ∈ {3,4,6}. From Clue 4, Z is 1 shelf below P, so (Z,P) ∈ {(1,2), (2,3), (3,4), (4,5), (5,6)}. Since W = 2 and Y = 5, (Z,P) ∈ {(1,2), (3,4), (4,5), (5,6)}. But (1,2) has P=2=W, (4,5) has P=5=Y, (5,6) has Z=5=Y. So (Z,P) = (3,4). Then Z = 3, P = 4. Remaining items: X, Q for shelves 1, 6. From Clue 2, X > 2, so X ∈ {3,4,6}. Since 3 and 4 are taken, X = 6. Then Q = 1. Verify: Q(1), W(2), Z(3), P(4), Y(5), X(6). Clue 1: W=2 ✓. Clue 2: X=6 > W=2 ✓. Clue 3: Y=5 ✓. Clue 4: Z=3 is 1 below P=4 ✓. Answer: P on shelf 4.

Question 5

Five people—P, Q, R, S, and T—live on 5 consecutive floors (1 to 5). Each person lives on a different floor. Based on the clues below, who lives on Floor 2?

Clue 1: P lives on Floor 1.
Clue 2: Q lives exactly 2 floors above P.
Clue 3: R lives immediately below Q.
Clue 4: S and T occupy the remaining floors.

Accepted Answer

From Clue 1, P is on Floor 1. From Clue 2, Q is 2 floors above P, so Q is on Floor 3. From Clue 3, R is immediately below Q, so R is on Floor 2.

Question 6

Six people—A, B, C, D, E, and F—live on 6 floors (1 to 6). Based on the clues below, who lives on Floor 5?

Clue 1: A lives on Floor 1.
Clue 2: B lives 2 floors above A.
Clue 3: C lives immediately above B.
Clue 4: D lives on Floor 6.
Clue 5: E and F live on the remaining floors, with E on a lower floor than F.

Accepted Answer

From Clue 1, A is on Floor 1. From Clue 2, B is 2 floors above A, so B is on Floor 3. From Clue 3, C is immediately above B, so C is on Floor 4. From Clue 4, D is on Floor 6. Remaining floors are 2 and 5 for E and F. Since E is on a lower floor than F (Clue 5), E is on Floor 2 and F is on Floor 5.

Question 7

Five people—W, X, Y, Z, and V—live on 5 floors (1 to 5). Based on the clues below, who lives on Floor 1?

Clue 1: Z lives on Floor 5.
Clue 2: W lives on Floor 3.
Clue 3: Y lives immediately below W.
Clue 4: X and V live on the remaining floors, with X on a higher floor than V.

Accepted Answer

From Clue 1, Z is on Floor 5. From Clue 2, W is on Floor 3. From Clue 3, Y is immediately below W, so Y is on Floor 2. Remaining floors are 1 and 4 for X and V. Since X is on a higher floor than V (Clue 4), V is on Floor 1 and X is on Floor 4.

Question 8

Five boxes—P, Q, R, S, T—are stacked on five different floors (1 to 5, bottom to top). (1) R is not on floor 1. (2) Q is exactly one floor below S. (3) P is on a floor higher than R. (4) T is on the topmost floor. (5) S is not on floor 5. Which box is on floor 3?

Accepted Answer

Constraint satisfaction puzzle. From clue 4: T=5. From clue 2: Q=S-1, so (Q,S) ∈ {(1,2), (2,3), (3,4), (4,5)}. From clue 5: S≠5, so (Q,S) ∈ {(1,2), (2,3), (3,4)}. From clue 1: R≠1. From clue 3: P>R. Remaining boxes for floors 1-4: P, Q, R, S. Case 1: (Q,S)=(1,2). Then P, R ∈ {3,4}. R≠1 (satisfied). P>R means P=4, R=3. Floors: Q=1, S=2, R=3, P=4, T=5. Check clue 3: P(4)>R(3) ✓. Case 2: (Q,S)=(2,3). Then P, R ∈ {1,4}. R≠1, so R=4, P∈{1}. But P>R means P>4, impossible. Case 3: (Q,S)=(3,4). Then P, R ∈ {1,2}. R≠1, so R=2, P∈{1}. But P>R means P>2, impossible. **Solution**: Q=1, S=2, R=3, P=4, T=5. Floor 3 = **R**.

Question 9

Six employees—P, Q, R, S, T, U—work on three floors (Ground, First, Second) with exactly two employees per floor. Each has a unique designation: Manager, Assistant, Clerk, Technician, Supervisor, Coordinator.

Conditions:
1. P and Q are on the same floor.
2. R is on a higher floor than S.
3. T is the Manager and lives on the Ground floor.
4. U is the Coordinator and lives on the Second floor.
5. S is the Clerk and lives on the Ground floor.
6. The Assistant lives on the First floor.
7. R is the Technician.

What is R's designation and floor?

Accepted Answer

From condition 7, R is the Technician. From condition 3, T is the Manager on Ground floor. From condition 5, S is the Clerk on Ground floor. From condition 4, U is the Coordinator on Second floor. From condition 2, R is on a higher floor than S. Since S is on Ground floor, R must be on First or Second floor. From condition 6, the Assistant is on First floor. Since R is the Technician (not Assistant), R cannot be on First floor. Therefore, R must be on Second floor. R's designation is Technician and floor is Second.

Question 10

Six boxes—Box1, Box2, Box3, Box4, Box5, Box6—are stacked on six shelves (Shelf 1 at bottom to Shelf 6 at top). Each box contains a unique item: Gold, Silver, Bronze, Diamond, Emerald, Ruby.

Conditions:
1. Gold is not on Shelf 1 or Shelf 6.
2. Silver is on a shelf higher than Gold.
3. Bronze is on Shelf 3.
4. Diamond is on a shelf lower than Bronze.
5. Emerald is on a shelf higher than Silver.
6. Ruby is on Shelf 1.
7. The item on Shelf 5 is not Emerald.

Which item is on Shelf 5?

Accepted Answer

From conditions: Ruby on Shelf 1, Bronze on Shelf 3. From condition 4, Diamond on shelf < 3, so Shelf 1 or 2. Since Ruby is on Shelf 1, Diamond is on Shelf 2. From condition 1, Gold on Shelf 2, 3, 4, or 5. Since Shelf 2 has Diamond and Shelf 3 has Bronze, Gold is on Shelf 4 or 5. From condition 2, Silver > Gold. If Gold on Shelf 4, Silver on Shelf 5 or 6. If Gold on Shelf 5, Silver on Shelf 6. From condition 5, Emerald > Silver. If Silver on Shelf 6, Emerald > 6 (impossible). So Silver is not on Shelf 6. Therefore, Gold is on Shelf 4, and Silver is on Shelf 5. From condition 5, Emerald > Silver (Shelf 5), so Emerald on Shelf 6. From condition 7, item on Shelf 5 is not Emerald. Silver is on Shelf 5, which satisfies condition 7. Answer: Silver.
