Javier Jorge starts walking towards South. After walking 25 meters he reaches the bus stop and then he goes towards North. After walking 30 metres, he turns towards East and walks another 10 metres.

B. 10 m, North

Let the bus stop be (0, 0). He walks 30m North to (0, 30), turns East for 10m to (10, 30), and turns South for 30m to (10, 0). He is exactly 10m East of the bus stop.
A and B are standing at a distance of 20 km from each other on a straight road running East-West. From there they start moving towards east and west at the same time. After covering a distance of 5 km, A turns to his left and walks 10 km, while B after covering a distance of 5 km turns to his right and walks 10 km. After that both turn to their left and cover a distance of 5 km. What is the distance between them now?
Explanation:
Assume A at (0,0), B at (20,0). A moves east 5 → (5,0); left (north) 10 → (5,10). B moves west 5 → (15,0); right (north) 10 → (15,10). Both turn left (west) 5: A → (0,10), B → (10,10). Distance = 10 km.
Vinayak walks 5m in South and then he turns to his left and walks 12m. After that he again turns towards south and walks 8 metres. Then he turns to his right and walks 15 metres. In which direction is Vinayak now with respect to his starting point?
Explanation:
Path: 5m South, 12m East (left turn), 8m South, 15m West (right turn). Total South = 5 + 8 = 13m. Total West = 15 - 12 = 3m. Since he is South and West of his origin, he is in the South-West direction.
