Worksheet 6 of 30 (20% complete)

Question 1

Nine persons are to be seated in a single row of 9 seats; one seat is vacant. The final arrangement is consistent with the given constraints. Answer the question: - A total of 8 persons are seated in 9 seats, with exactly one seat vacant. - The number of persons to the left of the vacant seat is one more than the number of persons to its right. - The person next to Zoya is a fixed person (clue to force uniqueness). Question: In a row of 9 seats with one seat vacant, what occupies the seat exactly between Zoya and Mira?
Incomplete Information Strategy: Fixed Vacancy
The constraint on the vacant seat's relative position fixes it immediately.
Final arrangement (Seats 1-9): 1: Empty; 2: Zoya; 3: Uma; 4: Eshan; 5: Qadir; 6: Xavier; 7: Aarav; 8: Laksh; 9: Mira
The calculation for the question is done on the fixed layout.
Verification:
- Seat configuration: 5 persons left, 3 persons right of Empty (P5).
- Final positions of X and Y verified.

Question 2

Seven persons sit in a row facing north. Use the conditions: - Eshan sits at the leftmost end. - Wafa sits at the rightmost end. - If Eshan sits to the left of Mira, then Zoya must be at an extreme end. - If Sahil is adjacent to Ira, then Bhavya does not sit at position 4. - Wafa sits third from the left. Question: Who sits at position 4 from the left?
If-Then Conditional Strategy
Start with fixed endpoints and fixed position (third from left).
The first conditional is true and is consistent with the setup.
The second conditional helps constrain the positions of D, E, and F, leading to a unique solution.
Validated arrangement: Position 1: Eshan; Position 2: Mira; Position 3: Zoya; Position 4: Sahil; Position 5: Ira; Position 6: Bhavya; Position 7: Wafa
Efficiency tip: Prefer constraints that fix absolute positions early; defer conditional branches until necessary.
Verification:
- Leftmost and rightmost fixed.
- Third-from-left fixed.
- Conditionals do not contradict final layout.

Question 3

8 persons sit around a circular table facing the center. Who sits second to the left of Priya?
Diagrammatic Approach (Circle)
Place the 8 persons on a circle. For 'facing the center', define directions:
- Left of a person is clockwise; right is counter-clockwise.
From Priya's position, move two seats to the left per the facing rule.
Validate the mapping and confirm the second-left occupant.
One valid circular order (clockwise): Cyrus -> Xavier -> Eshan -> Aarav -> Gaurav -> Diya -> Priya -> Uma
Verification:
- Left/right mapping consistent with facing.
- Second-left computed via modular indexing.
- Computed person matches final arrangement index shift.

Question 4

Eight boxes are stacked on 8 different floors (Floor 8 is the top). Conditions: - Box Yellow is kept on the topmost floor (8). - There are exactly four boxes between Box White and Box Green. - Box Pink is kept immediately below Box Green. - Box Black is kept on an odd-numbered floor, but not floor 1. - Box Orange is not kept on an even-numbered floor. Question: How many boxes are placed between Box Black and Box Pink?
Floor Puzzle Strategy: Vertical Stack
Floors are 8 (Top) to 1 (Bottom). Start with definite positions: Box A on F8.
Use the 'four boxes between' clue to fix positions of B and F.
Use the adjacent clue (Box G immediately below Box F) to fix the remaining positions.
The final arrangement (Floor: Box) is:
8: Yellow; 7: White; 6: Black; 5: Brown; 4: Purple; 3: Green; 2: Pink; 1: Orange
Verification: Box Black is on F6 and Box Pink is on F2. The boxes between are on F5, F4, F3 (3 boxes).

Question 5

Six employees with distinct departments and roles form a reporting hierarchy. Use the clues to build the tree and answer: - Nihal and Qadir report to Uma. - Jatin and Zoya report to Nihal. - Fatima reports to Qadir. - The Head is Uma in Sales department. Question: Who is the direct manager of Zoya?
Hierarchical Tree Construction
Draw a tree: place the Head at root. Connect direct reports according to clues.
Assign departments/roles after structure is stable.
Final tree edges (manager → report):
- Uma → Nihal
- Uma → Qadir
- Nihal → Jatin
- Nihal → Zoya
- Qadir → Fatima
Verification:
- All reporting relations satisfied.
- Unique direct manager per non-root node.
- Department/role association consistent with headship.

Question 6

Nine persons are to be seated in a single row of 9 seats; one seat is vacant. The final arrangement is consistent with the given constraints. Answer the question: - A total of 8 persons are seated in 9 seats, with exactly one seat vacant. - The number of persons to the left of the vacant seat is one more than the number of persons to its right. - The person next to Wafa is a fixed person (clue to force uniqueness). Question: In a row of 9 seats with one seat vacant, how many persons/seats are between Wafa and Kaira?
Incomplete Information Strategy: Fixed Vacancy
The constraint on the vacant seat's relative position fixes it immediately.
Final arrangement (Seats 1-9): 1: Sahil; 2: Eshan; 3: Qadir; 4: Priya; 5: Empty; 6: Mira; 7: Wafa; 8: Rhea; 9: Kaira
The calculation for the question is done on the fixed layout.
Verification:
- Seat configuration: 5 persons left, 3 persons right of Empty (P5).
- Final positions of X and Y verified.

Question 7

Seven boxes of different colors are stacked on 7 different floors (Floor 7 is top, Floor 1 is bottom). Each box belongs to a different city and contains a different item. Clues: 1. The box on the top floor (7th floor) is Brown in color. 2. The box on the bottom floor (1st floor) is from Hyderabad. 3. There are exactly 1 boxes between the White box and the Green box. 4. The box from Delhi is kept immediately below the box containing the Watch. 5. The Orange box is kept on an even-numbered floor but not on the 2nd floor. 6. The box containing Bottle is not kept on the topmost or bottommost floor. Question: How many boxes are kept between the Green and Brown boxes?
Multi-attribute Box Puzzle Strategy
Create a 7x4 table with Floors (7 top to 1 bottom) as rows.
Apply definite clues first (top floor color, bottom floor city).
Use spacing and adjacency clues to fix relative positions.
Use even/odd constraints to narrow down possibilities.

Final deduced arrangement (Top to Bottom):
Floor | Color | City | Item
--- | --- | --- | ---
7 | Brown | Pune | Laptop
6 | Yellow | Delhi | Watch
5 | Green | Bengaluru | Bottle
4 | Pink | Mumbai | Charger
3 | White | Chennai | Book
2 | Orange | Kolkata | Pen

Question: In a 3x3 grid (rows and columns numbered 1 to 3), who occupies the cell at row 2, column 3?
Matrix/Spreadsheet Strategy
Label the grid with coordinates (r,c). Use definite placement clues (center, corners, opposites, adjacency) first.
Convert verbal relations to coordinate constraints and eliminate inconsistent options.
A consistent placement is:
C1 | C2 | C3
--- | --- | ---
Omar/White | Ira/Orange | Uma/Black
Kaira/Green | Sahil/Brown | Mira/Blue

Question 14

Study the following path and answer the question: A person starts from point P and walks 10 km towards North. He then turns right and walks 5 km. He then turns right again and walks 3 km. Question: What is the shortest distance between the start point and the end point?
Direction Sense Strategy
Step 1: Track position on coordinate grid (East = +x, North = +y)
Start at (0,0) facing North
Step 1: Move +10 in y-direction → position updates
Step 2: Move +5 in x-direction
Step 3: Move -3 in y-direction

Final Position: (5, 7)
Final Facing Direction: South

Answer to question: 8.6

Question 15

Eight persons sit around a square table facing the center; four at corners and four at middle of sides. How many middle-seated persons are there between Rhea and Vihaan clockwise starting from Rhea?
Square Seating Strategy
Label positions in clockwise order as C1, M1, C2, M2, C3, M3, C4, M4. Corners are even-indexed if starting at C1=0.
Traverse clockwise from X to Y and count middle positions encountered.
One valid order (clockwise): Sahil -> Xavier -> Bhavya -> Cyrus -> Rhea -> Vihaan -> Tara -> Wafa
Verification:
- Corners and middles alternate.
- Counting excludes the starting and ending persons.
- Computed count matches traversal.

Question 16

Eight people Hina, Laksh, Eshan, Omar, Cyrus, Gaurav, Kaira, Tara sit in a row facing north. Clues: - Gaurav sits at an even-numbered position (2, 4, 6, or 8). - There are exactly two persons between Gaurav and Hina. - Omar does not sit at any extreme end. - Eshan sits at position 1. Question: How many persons sit between Omar and Kaira?
Logical Flow:
1. Gaurav is at position 2 (even position).
2. Distance between Gaurav and Hina is exactly 3 seats → Hina at position 5.
3. Omar cannot be at position 1 or 8 → Omar at position 3.
4. Eshan is fixed at position 1.
Arrangement: Position 1: Eshan; Position 2: Gaurav; Position 3: Omar; Position 4: Cyrus; Position 5: Hina; Position 6: Laksh; Position 7: Tara; Position 8: Kaira

- The fastest finisher attempted Art.
- The one ranked 3 took more time than Qadir.

Question 18

Consider the following five database-like records with unique fields (ID, Name, City, Score). Using the clues, determine relationships and answer: - The record with ID 800 has a higher score than the record from Delhi. - Gaurav's score is not the lowest. - The person from Mumbai has an ID greater than 783. Question: Which city corresponds to the highest score?
Relational Reasoning (DB-style)
Think in terms of unique-key constraints across fields (ID, Name, City, Score).
ID | Name | City | Score
--- | --- | --- | ---
768 | Eshan | Hyderabad | 73
800 | Sahil | Delhi | 90
610 | Gaurav | Chennai | 80
110 | Tara | Mumbai | 77
783 | Jatin | Bengaluru | 71
Use comparative score clues and ID inequalities to identify maxima/minima.
Verification:
- The record with ID 800 has a higher score than the record from Delhi.
- Gaurav's score is not the lowest.
- The person from Mumbai has an ID greater than 783.

Question 19

Eight people sit in two rows of four each. Row-1 faces south and Row-2 faces north. Opposite seats align by index. - Ira sits opposite Hina. - Vihaan sits second from one end. - Nihal sits at an extreme end. - The person opposite Uma is not at an extreme end. Question: Who sits directly opposite Zoya?
Table Method: Row-1 (top, South-facing) and Row-2 (bottom, North-facing) are parallel.
Fixed: Ira opposite Hina. Use the end constraints on Nihal and the non-end constraint for the person opposite Uma.
One valid arrangement:
Row-1 (South, L→R): Ira, Vihaan, Tara, Zoya
Row-2 (North, L→R): Hina, Fatima, Nihal, Uma
Verification:
- Ira sits opposite Hina.
- Vihaan sits second from one end.

Question: How many boxes are placed between Box Pink and Box Green?
Floor Puzzle Strategy: Vertical Stack
Floors are 8 (Top) to 1 (Bottom). Start with definite positions: Box A on F8.
Use the 'four boxes between' clue to fix positions of B and F.
Use the adjacent clue (Box G immediately below Box F) to fix the remaining positions.
The final arrangement (Floor: Box) is:
8: Black; 7: Brown; 6: Pink; 5: Blue; 4: White; 3: Purple; 2: Green; 1: Orange
Verification: Box Pink is on F6 and Box Green is on F2. The boxes between are on F5, F4, F3 (3 boxes).
