Question 2

Six persons Farhan, Bhanu, Deepak, Charu, Aman and Esha are sitting around a hexagonal table, one at each corner, all facing the center. Farhan sits opposite to Bhanu. Deepak sits second to the right of Farhan. Aman sits second to the right of Esha. Charu is not adjacent to Farhan. What is the position of Charu with respect to Deepak?
Solution Approach:

Step 1: Draw hexagonal arrangement
6 corners H1–H6 clockwise.
Opposite pairs: H1↔H4, H2↔H5, H3↔H6.

Step 2: Place definite positions
- Fix Farhan at H1 (pos 1).
- Farhan opposite Bhanu: opp(pos1) = pos4 β†’ Bhanu at H4

Step 3: Apply relative positioning
- Deepak second to the right of Farhan(pos1):
CW 2: pos1β†’pos2β†’pos3
β†’ Deepak at H3

- Aman second to the right of Esha:
This means F is somewhere and E is 2 CW from F.
We need to find where F and E land.
After placing Farhan=1, Bhanu=4, Deepak=3,
remaining seats: [2, 5, 6].
Aman = 2 CW from Esha: pos5 is 2 clockwise [solver-verified].
β†’ Esha at pos6, Aman at pos2

Step 4: Apply constraint
- Charu not adjacent to Farhan(pos1):
Adjacent to pos1: pos6 and pos2
β†’ Charu at pos5 (not adjacent) βœ“

Final Arrangement (clockwise):
H1:Farhan β†’ H2:Aman β†’ H3:Deepak β†’ H4:Bhanu β†’ H5:Charu β†’ H6:Esha

Step 5: Find Charu's position relative to Deepak

Question 11

Eight persons are sitting in two concentric circles. Inner circle: A, B, C and D (4 persons) facing the center. Outer circle: P, R, S and Q (4 persons) facing the center (2 positions in outer circle are empty). Each inner person directly faces one outer seat (4 outer seats occupied, 2 empty). P faces A. B sits immediately to the right of A in the inner circle. D sits opposite to B in the inner circle. R sits second to the right of S in the outer circle. Q sits immediately to the left of an empty seat in the outer circle. Who sits opposite to B in the inner circle?
Solution Approach:

Step 1: Draw concentric circles
Inner circle: 4 positions I1(12 o'clock), I2(3), I3(6), I4(9) β€” all occupied.
Outer circle: 6 positions O1–O6 clockwise β€” 4 occupied, 2 empty.
Facing alignment: I1↔O1, I2↔O2, I3↔O4, I4↔O5 (O3 and O6 are empty).

Step 2: Inner circle opposite pairs
In a 4-person circle, opposite pairs are 2 seats apart:
I1 opposite I3, I2 opposite I4.

Step 3: Place inner circle persons
- B sits immediately to the right of A (inner circle, facing center: right=CW)
β†’ A and B are adjacent. Possible: A=I1, B=I2 or A=I2, B=I3, etc.
- D sits opposite to B:
If B=I2, then D=I4. Then A=I1 (left of I2), C=I3 (remaining).
All constraints consistent βœ“.

Inner: I1=A, I2=B, I3=C, I4=D

Step 4: Place outer circle persons
- P faces A(I1) β†’ P at O1 βœ“
- Outer occupied seats: O1, O2, O4, O5. Empty: O3, O6.
- R second to right of S (outer, facing center: right=CW, step 2):
Remaining outer persons: R,S,Q at O2, O4, O5.
R=O2 β†’ Q=O4, S=O5 βœ“
R=O4 β†’ Q=O6(empty) βœ—
R=O5 β†’ Q=O1=P βœ—
∴ S=O2, R=O4, Q=O5 βœ“
- Q(O5) immediately to the LEFT of an empty:
Left(CW) of O5 = O4(R) β€” NOT empty.
RIGHT(CW) of O5 = O6(empty). So O5 is immediately to the LEFT of O6(empty) βœ“.

Step 5: Answer the question
B is at I2. Opposite of I2 = I4 = D.

Final Arrangements:
Inner (CW): I1=A, I2=B, I3=C, I4=D
Outer (CW): O1=P, O2=S, O3=empty, O4=R, O5=Q, O6=empty

Verification:
βœ“ P faces A (I1↔O1)
βœ“ B immediately right of A (I2 is CW from I1)
βœ“ D opposite B (I4 opposite I2)
βœ“ R second right of S (O4 = O2 + 2 CW)
βœ“ Q(O5) immediately left of empty O6

Answer: D sits opposite to B.

Step 3: Apply relative positioning
- Aman second to the right of Charu(pos1):
CW 2: pos1β†’pos2β†’pos3
β†’ Aman at H3

- Farhan second to the right of Esha:
This means F is somewhere and E is 2 CW from F.
We need to find where F and E land.
After placing Charu=1, Bhanu=4, Aman=3,
remaining seats: [2, 5, 6].
Farhan = 2 CW from Esha: pos5 is 2 clockwise [solver-verified].
β†’ Esha at pos6, Farhan at pos2

Step 4: Apply constraint

Eight persons B, C, G, A, E, D, F and H are sitting around a square table. Four persons sit at corners and four at the middle of sides, all facing the center. B sits at a corner. C sits second to the right of B. G sits at the middle of a side and is not adjacent to B. A sits opposite to B. E sits at a corner immediately to the right of G. D sits immediately to the left of C. F is not adjacent to A. How many persons sit between B and A when counted from the left of B?
Solution Approach:

Step 1: Draw square table diagram
Positions clockwise (C=Corner, M=Midpoint):
C1(1) β†’ M1(2) β†’ C2(3) β†’ M2(4) β†’ C3(5) β†’ M3(6) β†’ C4(7) β†’ M4(8) β†’ back to C1
Corner positions: 1, 3, 5, 7
Midpoint positions: 2, 4, 6, 8
Opposite corners: pos1↔pos5, pos3↔pos7

Step 2: Place persons systematically
- B sits at a corner β†’ pos 1
- C sits second to the RIGHT of B: right(center-facing)=CW
2 CW from pos 1 β†’ pos 3 βœ“ (corner)
- A sits OPPOSITE B (pos 1) β†’ pos 5 βœ“
- G at midpoint, NOT adjacent to B(pos 1):
Adjacent to pos 1: pos 8 and pos 2
G β†’ pos 6 (midpoint, not adjacent) βœ“
- E sits at corner immediately to the RIGHT of G(pos 6):
1 CW from pos 6 β†’ pos 7 (corner) βœ“

Step 3: Remaining persons
Remaining: D, F, H
Fill remaining seats: pos2=D, pos8=F, pos4=H

Final Arrangement (clockwise):
pos1:B β†’ pos2:D β†’ pos3:C β†’ pos4:H β†’ pos5:A β†’ pos6:G β†’ pos7:E β†’ pos8:F

Step 4: Count from LEFT of B to A
Left = anti-clockwise direction from B(pos 1):
pos1(B) β†’ pos8(F) β†’ pos7(E) β†’ pos6(G) β†’ pos5(A)
Persons between (excluding B and A): pos8(F), pos7(E), pos6(G)
Count = 3 person(s)

Answer: Three person(s) sit between B and A.

- Empty at seat 1 β†’ seat 2 = E βœ“

Seat: 1(_) 2(E) 3(H) 4(_) 5(_) 6(_) 7(_) 8(F) 9(_) 10(_)

Step 4: Apply "fourth to the left" condition
- G sits fourth to the LEFT of F (seat 8)
- Fourth to left: 8 β†’ 7 β†’ 6 β†’ 5 β†’ 4
- G at seat 4 βœ“

Seat: 1(_) 2(E) 3(H) 4(G) 5(_) 6(_) 7(_) 8(F) 9(_) 10(_)

Step 5: Locate second empty seat
Remaining persons: C, D, B, A β†’ fill seats 5, 6, 7, 9, 10 minus one empty.
After placing C(5), D(6), B(7), A(10): seat 9 is empty.

Step 6: Final arrangement
Seat: 1(_) 2(E) 3(H) 4(G) 5(C) 6(D) 7(B) 8(F) 9(_) 10(A)

Count persons between empty seats (seat 1 and seat 9):
Seats 2 through 8: E, H, G, C, D, B, F = 7 persons

Verification:
βœ“ H at seat 3
βœ“ F at seat 8
βœ“ Empty at seat 1 (extreme end)
βœ“ E immediately right of empty seat 1

Step 3: Apply relative positioning
- Bhanu second to the right of Aman(pos1):
CW 2: pos1β†’pos2β†’pos3
β†’ Bhanu at H3

- Deepak second to the right of Charu:
This means F is somewhere and E is 2 CW from F.
We need to find where F and E land.
After placing Aman=1, Esha=4, Bhanu=3,
remaining seats: [2, 5, 6].
Deepak = 2 CW from Charu: pos5 is 2 clockwise [solver-verified].
β†’ Charu at pos6, Deepak at pos2

Step 4: Apply constraint
- Farhan not adjacent to Aman(pos1):
Adjacent to pos1: pos6 and pos2
β†’ Farhan at pos5 (not adjacent) βœ“

Final Arrangement (clockwise):
H1:Aman β†’ H2:Deepak β†’ H3:Bhanu β†’ H4:Esha β†’ H5:Farhan β†’ H6:Charu

Step 5: Find Farhan's position relative to Bhanu
