Suresh walks 18 km from his house towards the North. Then he turns towards the East and covers 12 km. He then turns towards the South and covers 6 km. Finally, he turns towards the West and covers 12 km. In which direction is he from his house?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → North
Keep a running total of the distance north (or south) and east (or west) of the house after each part of the walk.
18 km North: 18 km north of the house
12 km East: 18 km north, 12 km east
6 km South: \(18-6=12\) km north, 12 km east
12 km West: 12 km north, \(12-12=0\) km east
The east and west parts cancel, so Suresh is 12 km due North of his house.
