Question

Six persons, A, B, C, D, E and F, live in six bungalows, three of which face North and three face South. The bungalows are named after six different flowers: Yarrow, Periwinkle, Rose, Orchid, Blue Star and White Primrose, not necessarily in that order. The following facts are known:
1. C lives in the Yarrow bungalow and faces South.
2. There is no bungalow to the left of White Primrose.
3. The bungalow of D is to the right of the bungalow opposite that of B.
4. The bungalow opposite C is Periwinkle.
5. The bungalow opposite B faces North and it is not Rose.
6. The Blue Star bungalow is to the immediate left of Rose, and it faces North.
7. E lives in a bungalow that is to the right of F.

Who lives to the immediate left of B?

• A. A
• B. C
• C. F
• D. D

Hint:

Remember that the South row's own sense of left runs the opposite way to the North row's, since the two rows face each other.

Answer 1

The Correct Option is A

Rather than tracking each clue in the order given, it is quicker to fill a complete seating table first and then simply read off any neighbour relationship the question asks about.

1. North row flowers: Periwinkle sits opposite the South facing C, so Periwinkle is North. Blue Star sits right before Rose and also faces North, so the whole North row is Periwinkle, Blue Star and Rose in some order, and the South row is left with Yarrow, Orchid and White Primrose.
2. Exact order: since White Primrose (South) needs nothing to its left, Periwinkle has to be first in the North row, giving North as Periwinkle, Blue Star, Rose from left to right. C, sitting opposite Periwinkle, takes the Yarrow spot directly across from it. Because the South row looks the other way, its own leftmost spot is the one across from Rose, which goes to White Primrose, leaving Orchid in the middle South spot, across from Blue Star.
3. People: B cannot sit opposite Rose, so B takes the middle South spot, Orchid, across from Blue Star. D sits to the right of Blue Star (the bungalow across from B), so D takes the Rose bungalow. Of the three names left, A, E and F, only the two North bungalows and the White Primrose bungalow remain; since E must be to the right of F, F takes Periwinkle and E takes Blue Star, and A is left with White Primrose.

Now write the completed South row in its own left to right order: since South faces away from North, its own leftmost bungalow is White Primrose (A), then the middle one is Orchid (B), then Yarrow (C) at the far end.

Let's summarize:

• South row, South's own left to right order: A in White Primrose, B in Orchid, C in Yarrow.
• The bungalow immediately before B in that order belongs to A.

So A lives immediately to the left of B, option (a).
