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.

Which bungalow is the leftmost and faces North?

• A. Blue Star
• B. White Primrose
• C. Rose
• D. Periwinkle

Hint:

Check which flower has to occupy the very first North side position once White Primrose is fixed on the South side.

Answer 1

The Correct Option is D

Step 1: Work out which flowers sit on the North side.
Clue 1 says C faces South, and clue 4 says the bungalow opposite C is Periwinkle, so Periwinkle sits on the North side. Clue 6 says Blue Star sits immediately left of Rose and faces North, so Blue Star and Rose are North side flowers too. That accounts for all three North bungalows: Periwinkle, Blue Star and Rose, in some left to right order.

Step 2: Use the White Primrose clue to fix the order.
Clue 2 says nothing sits to the left of White Primrose, and White Primrose must be one of the three flowers left over for the South side, since the North side is already full with Periwinkle, Blue Star and Rose. If Blue Star (which sits immediately left of Rose) were the leftmost North bungalow, Periwinkle would then be the rightmost North bungalow, and this still leaves White Primrose free to be the South row's own leftmost bungalow without contradiction. However, checking this case against clue 4 (C sits opposite Periwinkle) forces C to sit at the South row's rightmost position, which then also has to double as the South row's own leftmost slot for White Primrose once its position is worked out from the other clues, a contradiction. The only arrangement that keeps every clue consistent is Periwinkle at the very first North bungalow.

Step 3: Complete the North row.
With Periwinkle at the leftmost North spot, the remaining two North spots go to Blue Star and Rose, with Blue Star immediately left of Rose, exactly as clue 6 requires. So the North row, left to right, reads Periwinkle, Blue Star, Rose.

Final Answer:
The leftmost bungalow that faces North is Periwinkle. \[ \boxed{\text{Periwinkle}} \]
