Question

Seven people A, B, D, E, G, H and K are sitting in a straight line facing the north. E is sitting at an extreme end of the line. B is an immediate neighbour of E. Only three people are sitting between A and E. A is sitting second to the right of G. H is neither an immediate neighbour of A nor B. K is sitting second to the right of D. How many people are sitting to the right of K?

• A. Zero
• B. Three
• C. One
• D. Two

Answer 1

Answer:

C. One

One person is sitting to the right of K.

1. E sits at an extreme end, and B is an immediate neighbour of E.

   • Let's test E on the far left (Position 1):

     • Position 1 = E

     • Position 2 = B

2. Only three people sit between A and E.

   • Leaving 3 spaces after E (positions 2, 3, 4), A must sit at position 5.

     • Position 5 = A

3. A is sitting second to the right of G.

   • This means G must be 2 spots to the left of A (Position 3).

     • Position 3 = G

4. K is sitting second to the right of D.

   • We need two empty spots separated by one seat. The only available spots left are positions 4, 6, and 7.

   • This forces D into position 4 and K into position 6.

     • Position 4 = D

     • Position 6 = K

5. Fill the remaining spot with H.

   • Position 7 is the only open slot left.

     • Position 7 = H

   • Check rule: H is neither an immediate neighbour of A (next to 5) nor B (next to 2). Since H is at position 7, it satisfies this condition perfectly.

Final Seating Arrangement

Position 1	Position 2	Position 3	Position 4	Position 5	Position 6	Position 7
E	B	G	D	A	K	H

Looking at position 6 (K), there is only one person (H) sitting to his right.
