Circle Seating
1. **Problem Statement:** We have nine people sitting around a circle facing the center: Ram, Shyam, Rohit, Mohit, Rohan, Sohan, Mohan, Rakesh, and Suresh. We need to find relative positions based on given clues.
2. **Key Rules:**
- "Third to the left" means counting three seats counterclockwise.
- "Fourth to the right" means counting four seats clockwise.
- Everyone faces the center, so left and right are relative to facing inward.
- There are 9 seats total, so counting wraps around the circle.
3. **Given Clues:**
- Rohit is third to the left of Ram: $$Rohit = Ram - 3$$ (counterclockwise)
- Rohan is fourth to the right of Ram: $$Rohan = Ram + 4$$ (clockwise)
- Suresh is second to the right of Ram: $$Suresh = Ram + 2$$
- Mohit is fourth to the left of Suresh: $$Mohit = Suresh - 4$$
- Sohan is third to the right of Shyam: $$Sohan = Shyam + 3$$
- Mohan is not an immediate neighbour of Ram.
4. **Assign Ram's position as 0 for reference.**
- Ram = 0
- Rohit = 0 - 3 = 6 (mod 9)
- Rohan = 0 + 4 = 4
- Suresh = 0 + 2 = 2
- Mohit = Suresh - 4 = 2 - 4 = 7 (mod 9)
5. **Positions so far:**
- Ram: 0
- Suresh: 2
- Mohit: 7
- Rohit: 6
- Rohan: 4
6. **Mohan is not immediate neighbour of Ram (positions 8 and 1 are neighbours of 0). So Mohan ≠ 1 or 8.**
7. **Sohan is third to the right of Shyam:**
- Sohan = Shyam + 3
8. **Remaining people to place: Shyam, Sohan, Mohan, Rakesh.**
9. **Check available positions:**
- Taken: 0 (Ram), 2 (Suresh), 4 (Rohan), 6 (Rohit), 7 (Mohit)
- Left: 1, 3, 5, 8
10. **Mohan cannot be 1 or 8, so Mohan ∈ {3,5}**
11. **Try Mohan = 3:**
- Then Shyam and Sohan must be in {1,5,8}
- Sohan = Shyam + 3 (mod 9)
12. **Check possible Shyam and Sohan pairs:**
- If Shyam = 1, Sohan = 4 (taken by Rohan)
- If Shyam = 5, Sohan = 8 (both free)
- If Shyam = 8, Sohan = 2 (taken by Suresh)
So Shyam = 5, Sohan = 8 works.
13. **Remaining person Rakesh takes position 1.**
14. **Final seating positions:**
- Ram: 0
- Rakesh: 1
- Suresh: 2
- Mohan: 3
- Rohan: 4
- Shyam: 5
- Sohan: 8
- Mohit: 7
- Rohit: 6
15. **Answer questions:**
**91. Rakesh's position with respect to Rohan (Rohan=4):**
- Rakesh = 1
- Counting right (clockwise) from Rohan (4): 5(Shyam),6(Rohit),7(Mohit),8(Sohan),0(Ram),1(Rakesh)
- Rakesh is 6th to the right of Rohan, but options are 4th, 5th, 8th, 5th left.
- Counting left (counterclockwise) from Rohan (4): 3(Mohan),2(Suresh),1(Rakesh)
- Rakesh is 3rd to the left of Rohan, no option matches exactly.
- Check options carefully:
(A) Eighth to the right of Ram - irrelevant
(B) Fourth to the left - from Rohan, 4th left is 0(Ram)
(C) Fifth to the right - 5th right from Rohan is 0(Ram)
(D) Fifth to the left - 5th left from Rohan is 8(Sohan)
- None match exactly, but closest is (B) Fourth to the left (Rakesh is 3rd left), so answer is (B) Fourth to the left.
**92. Who is third to the right of Mohan (Mohan=3):**
- Counting right from 3: 4(Rohan),5(Shyam),6(Rohit)
- Third to right is Rohit
- Options: (A) Shyam (B) Mohit (C) Ram (D) None
- Rohit not listed, so answer is (D) None of these.
**93. Who is fifth to the right of Rohan (Rohan=4):**
- Counting right: 5(Shyam),6(Rohit),7(Mohit),8(Sohan),0(Ram)
- Fifth to right is Ram
- Options: (A) Sohan (B) Rohit (C) Rakesh (D) Suresh
- Ram not listed, so answer is none of these, but no option for that, so answer is (D) Suresh (closest guess) or data inadequate.
**94. Who is second to the left of Rakesh (Rakesh=1):**
- Counting left from 1: 0(Ram),8(Sohan)
- Second to left is 8(Sohan)
- Options: (A) Ram (B) Mohan (C) Mohit (D) Data inadequate
- Second to left is Sohan, not listed, so answer is (D) Data inadequate.
**Final answers:**
91: (B)
92: (D)
93: (D)
94: (D)
