Data Arrangement Worksheet 5 - Beginner Level (data sequencing) | 20 Questions

Question 1

Five persons each like a distinct color and prefer a distinct subject. Use the clues to complete the table and answer: - Tara does not like Green or Physics. - The one who likes Red prefers Music. - Aarav prefers History. - Jatin does not prefer Art. - The Black-lover is not Mira. Question: Who likes the color Yellow?

Table Method
Create a 5x3 table with Person vs (Color, Subject). Use exclusion clues to mark X, and direct clues to fill ✓.
Process:
- Tara does not like Green or Physics.
- The one who likes Red prefers Music.
- Aarav prefers History.
- Jatin does not prefer Art.
- The Black-lover is not Mira.
After consistent deductions and elimination, the unique mapping is:
Person | Color | Subject
--- | --- | ---
Tara | Red | Art
Jatin | Green | Music
Aarav | Black | Physics
Mira | Yellow | History
Vihaan | Orange | Chemistry
Verification:
- Each color and subject used exactly once.
- All negative clues respected.
- Direct clues align with assignments.

Question 2

Nine distinct persons are arranged in a 3x3 matrix; each cell has exactly one person with a unique color. - The center cell is occupied by Tara who likes Black. - Hina sits opposite Uma on the grid edges. - Vihaan is at a corner and does not like Green. - Rhea is adjacent to Xavier. Question: In a 3x3 grid (rows and columns numbered 1 to 3), who occupies the cell at row 1, column 2?

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
--- | --- | ---
Fatima/Pink | Rhea/Purple | Xavier/Yellow
Hina/Red | Tara/Black | Uma/Green
Vihaan/Blue | Mira/Brown | Aarav/White
Verification:
- Center, opposite, and corner constraints satisfied.
- Adjacency satisfied by orthogonal neighbors.
- Each person/color used exactly once.

Question 3

Eight people sit around a circular table. Clues: - Four people face the Center and four face Outside. - Cyrus sits opposite Jatin and both face the Center. - The neighbors of Yash face the same direction, which is Center. - Laksh sits second to the left of Priya. - Qadir is not an immediate neighbor of Cyrus. Question: Who sits third to the right of Laksh?

Mixed Facing Strategy:
- Center-facing: Left is Clockwise, Right is Counter-Clockwise.
- Outside-facing: Left is Counter-Clockwise, Right is Clockwise.
Clockwise arrangement: Cyrus(Center) -> Yash(Outside) -> Priya(Center) -> Laksh(Outside) -> Jatin(Center) -> Ira(Outside) -> Qadir(Center) -> Bhavya(Outside)
Laksh faces Outside. 3rd Right is Cyrus.

Question 4

Eight people Uma, Vihaan, Eshan, Wafa, Qadir, Aarav, Cyrus, Fatima sit in a row facing north. Clues: - Eshan sits at an even-numbered position (2, 4, 6, or 8). - There are exactly two persons between Eshan and Aarav. - Uma does not sit at any extreme end. - Vihaan sits at position 1. Question: At which position from the left does Aarav sit?

Logical Flow:
1. Eshan is at position 4 (even position).
2. Distance between Eshan and Aarav is exactly 3 seats → Aarav at position 7.
3. Uma cannot be at position 1 or 8 → Uma at position 5.
4. Vihaan is fixed at position 1.
Arrangement: Position 1: Vihaan; Position 2: Fatima; Position 3: Cyrus; Position 4: Eshan; Position 5: Uma; Position 6: Wafa; Position 7: Aarav; Position 8: Qadir

Question 5

Study the following path and answer the question: A person starts from point A and walks 8 km East. He then turns left and walks 6 km. He then turns left and walks 8 km. He then turns left and walks 4 km. Question: What is the distance walked in the 3rd segment?

Direction Sense Strategy
Step 1: Track position on coordinate grid (East = +x, North = +y)
Start at (0,0) facing North
Step 1: Move +8 in x-direction
Step 2: Move +6 in y-direction → position updates
Step 3: Move -8 in x-direction
Step 4: Move -4 in y-direction

Final Position: (0, 2)
Final Facing Direction: South

Question 6

Six people sit in a row facing North. Conditions: - Diya sits at the extreme right end (Position 6). - There are three people sitting between Eshan and Xavier. - Sahil sits third to the right of Xavier. - Neither Bhavya nor Kaira sits at any extreme end. Question: Who is sitting second from the left end (Position 2)?

Ambiguity Strategy: Proving Non-Unique Solution
Step 1: Fix D (P6). Use the 'three between' clue (Clue 2) to determine the positions of F (P5) and B (P1).
Step 2: Use E's position (Clue 3) to fix E (P4).
The arrangement is fixed at: B, P2, P3, E, F, D.
Step 3: The remaining people are A and C for positions P2 and P3. Clue 4 prevents them from being at the ends, leaving two cases:
- Case 1: Xavier, Bhavya, Kaira, Sahil, Eshan, Diya
- Case 2: Xavier, Kaira, Bhavya, Sahil, Eshan, Diya
Since the person at Position 2 is either A or C (and both cases are valid), the answer is 'Cannot be determined'.

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 Black in color. 2. The box on the bottom floor (1st floor) is from Pune. 3. There are exactly 1 boxes between the Green box and the Purple box. 4. The box from Delhi is kept immediately below the box containing the Pen. 5. The Green box is kept on an even-numbered floor but not on the 2nd floor. 6. The box containing Watch is not kept on the topmost or bottommost floor. Question: On which floor is the Black box kept?

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 | Black | Mumbai | Laptop
6 | White | Bengaluru | Book
5 | Orange | Hyderabad | Charger
4 | Purple | Delhi | Pen
3 | Pink | Chennai | Bottle
2 | Green | Kolkata | Phone
1 | Blue | Pune | Watch

Direction Sense Strategy
Step 1: Track position on coordinate grid (East = +x, North = +y)
Start at (0,0) facing North
Step 1: Move +8 in x-direction
Step 2: Move +6 in y-direction → position updates
Step 3: Move -8 in x-direction
Step 4: Move -4 in y-direction

Final Position: (0, 2)
Final Facing Direction: South

Question 11

Six people sit in a row facing North. Conditions: - Zoya sits at the extreme right end (Position 6). - There are three people sitting between Xavier and Cyrus. - Diya sits third to the right of Cyrus. - Neither Gaurav nor Sahil sits at any extreme end. Question: Who is sitting at the immediate right of Diya?

Ambiguity Strategy: Proving Non-Unique Solution
Step 1: Fix D (P6). Use the 'three between' clue (Clue 2) to determine the positions of F (P5) and B (P1).
Step 2: Use E's position (Clue 3) to fix E (P4).
The arrangement is fixed at: B, P2, P3, E, F, D.
Step 3: The remaining people are A and C for positions P2 and P3. Clue 4 prevents them from being at the ends, leaving two cases:
- Case 1: Cyrus, Gaurav, Sahil, Diya, Xavier, Zoya
- Case 2: Cyrus, Sahil, Gaurav, Diya, Xavier, Zoya
The person immediately right of E is F in both valid cases, so the answer is uniquely determined.

Question 12

Six tasks T1–T6 have distinct priorities from 1 (highest) to 6 (lowest). Use the clues: - T4 has higher priority than T5. - T2 is the least urgent. - T6's priority is between T4 and T3. Question: Which task has the second-highest priority (just below the highest)?

Symbolic Reasoning with Inequalities
Priority chain (lower number = higher priority): T4(prio=1) > T6(prio=2) > T5(prio=3) > T3(prio=4) > T1(prio=5) > T2(prio=6)
From clues, derive inequalities and place tasks accordingly.
Verification:
- T4 has higher priority than T5.
- T2 is the least urgent.
- T6's priority is between T4 and T3.

Conditions: - Gaurav sits at the extreme right end (Position 6). - There are three people sitting between Sahil and Cyrus. - Xavier sits third to the right of Cyrus. - Neither Kaira nor Yash sits at any extreme end. Question: Who is sitting at the immediate right of Xavier?

Ambiguity Strategy: Proving Non-Unique Solution
Step 1: Fix D (P6). Use the 'three between' clue (Clue 2) to determine the positions of F (P5) and B (P1).
Step 2: Use E's position (Clue 3) to fix E (P4).
The arrangement is fixed at: B, P2, P3, E, F, D.
Step 3: The remaining people are A and C for positions P2 and P3. Clue 4 prevents them from being at the ends, leaving two cases:
- Case 1: Cyrus, Kaira, Yash, Xavier, Sahil, Gaurav
- Case 2: Cyrus, Yash, Kaira, Xavier, Sahil, Gaurav
The person immediately right of E is F in both valid cases, so the answer is uniquely determined.

Question 17

Seven persons sit in a row facing north. Use the conditions: - Eshan sits at the leftmost end. - Kaira sits at the rightmost end. - If Eshan sits to the left of Wafa, then Zoya must be at an extreme end. - If Qadir is adjacent to Nihal, then Mira does not sit at position 4. - Kaira 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: Wafa; Position 3: Zoya; Position 4: Qadir; Position 5: Nihal; Position 6: Mira; Position 7: Kaira
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.
