Question

A, B, C, D, E, F and G are sitting around a circular table facing the centre (but not necessarily in the same order) . Only two people sit between F and C when counted from the right of F. Only three people sit between B and G when counted from the right of G. C sits to the immediate right of G. D sits to the immediate right of A. Who sits fourth to the right of E?

• A. D
• B. G
• C. F
• D. A

Answer 1

Answer:

A. D

Let’s fix positions (7 people, all facing centre ⇒ right = anticlockwise, left = clockwise).

1. Fix G and C

• “C sits to the immediate right of G”
  So if G is at position 1 ⇒ C is at position 7.

  2. Place B using condition

• “Only three people sit between B and G when counted from the right of G”
  From G (1), moving right (anticlockwise):
  7 (C), 6, 5, 4 → so B = position 4

  3. Place F using condition

• “Only two people sit between F and C when counted from the right of F”
  C is at 7. Try F:

If F = 3: right → 2, 1, 7 ✔️ (two people between)
So F = 3

Place A and D

• “D sits to the immediate right of A”

Available seats: 2, 5, 6

Try:

• If A = 2 ⇒ D = 1 (occupied)

• If A = 5 ⇒ D = 4 (occupied)

• If A = 6 ⇒ D = 5

So A = 6, D = 5

Remaining seat

• Only position 2 left ⇒ E = 2

  Final arrangement (clockwise):

1(G), 2(E), 3(F), 4(B), 5(D), 6(A), 7(C)

Find fourth to the right of E

From E (2), move right (anticlockwise):

• 1st → 1 (G)

• 2nd → 7 (C)

• 3rd → 6 (A)

• 4th → 5 (D)

  Answer: D
