Deva comes out of his house and runs 30 meters in north-east direction. Afterwards, he runs 30 meters towards south-east direction. Afterwards, he runs 30 meters south-west. Finally, he runs 30 meters towards north-west direction. How far is he from his house?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 0 m
The four runs are of the same length, and each one turns a right angle from the one before (north-east, south-east, south-west, north-west), so the path is a square. The south-west run cancels the north-east run and the north-west run cancels the south-east run, so Deva is back at his house.
