- ASouth-East
- B(b) South-west
- C(c) North-East
- D(d) North-westCorrect
Explanation
The house faces East, so its backside is West.
- The man walks 25 meters straight down the backside of his house. This means he walks 25 meters West from his starting point.
- He then turns right. From facing West, a right turn means he is now facing North. He walks 50 meters North.
- He then turns left. From facing North, a left turn means he is now facing West. He walks 25 meters West.
From the starting point, he has moved a total of (25 + 25) = 50 meters West and 50 meters North. Therefore, his final position is North-West from his starting point.
Analyzing the options: A) South-East: Incorrect. This would imply moving East and South. B) South-west: Incorrect. This would imply moving West and South. C) North-East: Incorrect. This would imply moving East and North. D) North-west: Correct. His final position is West and North of his starting point.
The final answer is D) North-west.
