Comprehension
Eight people A, B, C, D, E, F, G and H are sitting on eight chairs kept symmetrically around a circular table, all facing the centre.
The following are known:
(i) F is sitting exactly opposite to C.
(ii) D is not next to F.
(iii) H is the only one sitting between G and C.
(iv) E is sitting two places to the right of B and is not next to F.
Question: 1

Which of the following is the correct position of H?

Show Hint

In circular seating, fix one person to break rotation, then test mutually exclusive patterns quickly; eliminate the impossible branch early to avoid heavy casework.

The Correct Option is B

Solution and Explanation

Step 1: Fix anchors using symmetry.
Place \(C\) at the top (without loss of generality). Since \(F\) is opposite \(C\), put \(F\) opposite \(C\).
Condition (iii) “\(H\) is the only one sitting between \(G\) and \(C\)” - the three consecutive seats are either \(G\!-\!H\!-\!C\) or \(C\!-\!H\!-\!G\).
Step 2: Try both orders; reject the impossible one.
If \(G\!-\!H\!-\!C\) (clockwise), then using (iv) \(E\) two to the right of \(B\) and “\(E\) not next to \(F\)” leads to a contradiction (no place for \(E\)).
Hence the only feasible order is \(C\!-\!H\!-\!G\) (clockwise).
Step 3: Place \(E\) and \(B\).
\(E\) is two to the right of \(B\) and not next to \(F\). The only way to satisfy both is \(E\) on the seat just before \(C\) (clockwise), which forces \(B\) two seats to its left (clockwise).
Step 4: Fill the remaining seats.
The last two seats go to \(A\) and \(D\), with \(D\) not next to \(F\) - \(D\) sits two to the right of \(F\).
Final circular order (clockwise): \(C,\;H,\;G,\;A,\;F,\;B,\;D,\;E\).
Here, \(H\) is directly opposite \(B\). \(\Rightarrow\) \(\boxed{\text{Exactly Opposite of B}}\).

Question: 2

Based on the same arrangement, which of the following statements is not correct?

Show Hint

After you lock a unique circular order, verify option statements directly from the ring—draw arrows for left/right (clockwise/counterclockwise) to avoid confusion.

  • B is to the immediate right of F.
  • G is sitting two places to the left of F.
  • There are only six persons whose sitting positions can be exactly determined.
  • All of these.

The Correct Option is C

Solution and Explanation

From the finalized order \(C,\;H,\;G,\;A,\;F,\;B,\;D,\;E\) (clockwise):
\(\bullet\) Immediate right of \(F\) is \(B\) \(\Rightarrow\) (a) is true.
\(\bullet\) Two places to the left of \(F\) is \(G\)\( \Rightarrow\) (b) is true.
\(\bullet\) All eight positions are uniquely fixed, not just six\( \Rightarrow \)(c) is false.
Hence the only statement that is not correct is \(\boxed{(c)}\).
