Directions : Study the following information carefully and answer the questions that follow:

Seven persons are sitting in a straight line. Four of them are facing south and remaining of them are facing north. They also like different fruits Apple, banana, grapes, guava, kiwi, mango and orange but not necessarily in the same order. Those seven people are also sitting in alphabetical order from left end.
The person who likes grapes sits second to the left of P. Two persons sit between the one who likes grapes and the one who likes banana. The immediate neighbours of the one who likes banana face opposite directions (i.e. if one faces north then the other faces south and vice versa). Q likes kiwi. The one who likes mango sits second to the right of Q. Only one person sits between R and the one who likes guava. The persons who like banana and Apple are immediate neighbours. The one who likes orange sits third to the right of the person who likes Mango. Q and R face opposite directions (i.e. if one faces north then the other faces south and vice versa). The one who likes banana faces south. The person who likes guava faces north.

Correct answer: A

Concept

In a row where people face north or south, each person reads "left" and "right" from their own viewpoint, so a directional clue is only usable once you know how that person faces. The dependable method is: fix the people first from the strongest positional clue, settle the facing of each anchor person using the direction clues, and only then convert each "left/right" clue into a seat. With seats numbered 1-7 from the left, a north-facing person's right hand points to the lower numbers and their left to the higher numbers, while a south-facing person's right points to the higher numbers and their left to the lower numbers.

Applying it

  1. The seven people sit in alphabetical order from the left end, so seats 1-7 are P, Q, R, S, T, U, V.

  2. Q likes kiwi, so kiwi is at seat 2. The direction clues force Q (seat 2) to face south and P (seat 1) to face north in the only consistent scenario, which is what makes the left/right clues resolve uniquely below.

  3. "Mango sits second to Q's right": Q faces south, so Q's right runs toward higher seat numbers; two seats that way from seat 2 is seat 4. Mango is at seat 4.

  4. "Orange sits third to the right of the mango-liker": the mango-liker at seat 4 also faces south, so three seats to their right is seat 7. Orange is at seat 7.

  5. "Grapes sits second to P's left": P (seat 1) faces north, so P's left runs toward higher seat numbers; two seats that way from seat 1 is seat 3. Grapes is at seat 3 - and seat 3 is R.

  6. Two people sit between the grapes-liker (seat 3) and banana, which places banana at seat 6.

  7. Banana and apple are immediate neighbours, so apple is at seat 5.

  8. The only fruit left, guava, takes seat 1; the clue that exactly one person sits between R (seat 3) and guava (seat 1) is satisfied, with seat 2 in between.

Result: R sits at seat 3, where grapes is placed, so R likes grapes.

Cross-check

Each fruit is used once and the direction clues hold: the banana-liker (seat 6) faces south with its two neighbours facing opposite each other, the guava-liker (seat 1) faces north, and Q (south) and R (north) face opposite directions. The arrangement is consistent and R likes grapes.
