There are 3 ladies who are not seated next to each other. J is between L and F. G is between I and F. H, a lady member is second to the left of J. F, a male member is seated opposite to E, a lady member. There is a lady member between F and I. Who among the following is to the immediate left of F ?

  1. A.

    G

  2. B.

    I

Show answer & explanation

Correct answer: C

Concept: In a circular or square-table seating puzzle, an 'X is between Y and Z' clue fixes X's two immediate neighbours as Y and Z. Two such clues sharing a common person merge into one continuous chain of neighbours, and an 'opposite' clue together with a 'nth-to-the-left-of' clue then anchor the remaining people onto that chain to complete the full seating ring.

Application:

  1. “J is between L and F” fixes one of F's neighbours as J, with L on J's far side: chain L - J - F.

  2. “G is between I and F” fixes F's other neighbour as G, since F can only have two neighbours: chain I - G - F. Merging both chains through F gives I - G - F - J - L.

  3. Three people (E, H, K) remain to be placed on the three still-empty seats of the eight-seat ring.

  4. “F, a male, is seated opposite E, a lady” places E exactly four seats from F, going round the ring in the same direction as the F-to-J step - i.e. three seats past J, past L.

  5. “H, a lady, is second to the left of J” places H two seats past J in that same direction - one seat past L.

  6. With E and H both fixed, the one seat still empty (between H and I) is taken by K.

  7. The completed ring, read consistently in this one direction, is: F - J - L - H - E - K - I - G - back to F.

Cross-check:

  • G is between I and F: the ring shows I - G - F consecutively.

  • J is between L and F: the ring shows F - J - L consecutively.

  • H is second to the left of J: going J, L, H is exactly two steps.

  • F (male) is opposite E (lady): F and E sit four seats apart on the eight-seat ring.

  • The three ladies (G, H and E) do not all sit together as one consecutive block, matching the condition given in the stem.

Reading the completed ring in the same fixed direction used throughout (F - J - L - H - E - K - I - G), F's immediate neighbour on this side is J.
