Directions : Read the following information carefully and answer the following

Eight persons—A, B, C, D, E, F, G and H—are sitting in a circular arrangement, all facing the center. Each of them has a unique card number ranging from 2 to 9. Each person holds a distinct card number ranging from 2 to 9.
Note: The difference between the card numbers of persons sitting adjacent to each other is more than 1.
C sits sixth to the right of the person whose card number is a prime number. Two persons sit between the person who sits second to the right of C and G. The person whose card number is a multiple of 5 is an immediate neighbour of G. F sits third to the right of the person whose card number is a multiple of 5. The person who sits opposite to the person whose card number is 5 has card number which is two less than card number G. The person whose card number is 8 sits second to the left of F. One person sits between the person who has 6 card number and H. A is an immediate neighbour of the person who has card number 6 and has card number that is a multiple of 3. Card number of B is not 2, 5 and 8. The person who sits second to the left of A has card number 4. The difference between card number of C and A is equal to card number of B. D is an immediate neighbour of the person who has card number 3. D is not an immediate neighbour of A and H. D doesn’t sit opposite to H and F. E is an immediate neighbour of G.

Who among the following person sits fourth to the right of the person who has card number 4?

  1. A.

    H

  2. B.

    B

  3. C.

    The person who has card number 5

  4. D.

    D

  5. E.

    None of these

Show answer & explanation

Correct answer: B

Concept

In a circular ‘facing-centre’ puzzle, every positional clue (right/left/opposite/between) fixes RELATIVE positions, while the value clues (card-number constraints) pin the numbers onto those seats. The winning method is to first lock the number clues that are most restrictive — here the adjacent-difference rule (any two neighbours differ by more than 1) plus the card-5 / card-8 / multiple-of-3 anchors — and only then read off the asked position. The arrangement is unique once all clues are combined; rotation of the whole circle never changes who sits relative to whom.

Application

Resolving the value clues step by step:

  1. ‘Opposite to card 5 has a number two less than G’ and ‘card 5 is G’s neighbour’ force G = 8 (so the seat opposite 5 holds 6) and place card 5 next to G.

  2. ‘Card 8 sits second to the left of F’ and ‘F sits third to the right of card 5’ position F, fixing F’s card as 4.

  3. ‘A is adjacent to card 6 and A’s card is a multiple of 3’ gives A = 9 (the only multiple of 3 left that satisfies every neighbour-difference).

  4. ‘Second to the left of A is card 4’, ‘|C − A| = B’, and ‘B is not 2, 5 or 8’ resolve the rest: C = 6, B = 3, D = 5, E = 2, H = 7.

  5. Every adjacent pair then differs by more than 1, confirming the single valid layout.

Final card mapping: A = 9, B = 3, C = 6, D = 5, E = 2, F = 4, G = 8, H = 7. The person holding card number 4 is F.

Cross-check / Result

Counting four positions to the right of F (card 4) lands on the person holding card 3, which is B. Re-tracing all neighbour differences (3, 2, 2, 6, 3, 2, 4, 2) confirms each exceeds 1, so the arrangement is consistent.

  • H (card 7): sits elsewhere in the circle, not four to the right of card 4 — rejected by the fixed positions.

  • ‘The person who has card number 5’ is D, who is not four to the right of F either.

  • D (card 5): same position as above — does not occupy the asked seat.

  • ‘None of these’ is wrong because a valid person, B, does occupy that seat.

  • Hence the person four to the right of card 4 is B (card 3).
