From a point, Shalu starts walking towards North. After walking 20 metres, she…

Concept: On a standard compass, facing North, each right turn rotates the direction clockwise (North → East → South → West → North), and each left turn rotates it anticlockwise (North → West → South → East → North). To find the final direction from the start, track the walker's position on two perpendicular axes — north–south (vertical) and east–west (horizontal) — by summing the signed distance walked along each axis across every leg; the net displacement on both axes fixes the final direction (equal positive north and east displacement gives North-East, and so on).

Applying this to the walk:

1. Start at O (0, 0), facing North. Walk 20 m North to point B (0, 20).

2. At B, turn right — from North, a right turn faces East. Walk 10 m East to point C (10, 20).

3. At C, turn right again — from East, a right turn faces South. Walk 20 m South to point D (10, 0).

4. At D, turn left — from South, a left turn faces East. Walk 10 m East to point E (20, 0).

5. At E, turn left again — from East, a left turn faces North. Walk 20 m North to point F (20, 20), the final point.

Cross-check: summing the vertical legs separately, net north-south displacement = 20 m north + 20 m north − 20 m south = 20 m north. Summing the horizontal legs, net east-west displacement = 10 m east + 10 m east = 20 m east. The two net displacements are equal and both positive, so F lies exactly North-East of O.

Therefore, Shalu is in the North-East direction with reference to the starting point.
