Manisha goes 40 m to the South of her house, then turns left and goes another 10 m. Then, turning to the North, she goes 20 m and then starts walking towards her house. In which direction is she walking now?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → North-West
A left turn moves the facing direction one step anticlockwise (South → East). Find where she ends up from her house; the way back is the opposite of that.
Facing South, 40 m: 40 m south of the house
Turns left, now facing East, 10 m: 40 m south, 10 m east
Turns to the North, 20 m: \(40-20=20\) m south, 10 m east
She is south and east of the house, so to reach it she must move north and west at the same time
She is walking North-West.
