1. A man walks 3 km north, then turns right and walks 4 km. He then turns right and walks 5 km. What direction is he facing now?
Correct Answer: b) South
Explanation: 1. Starts facing North 2. Walks 3 km North (still facing North) 3. Turns right → now faces East, walks 4 km 4. Turns right → now faces South, walks 5 km Final facing direction: South Path Diagram: N ↑ 3km → E 4km ↓ S 5km Short Trick: Each right turn changes facing direction 90° clockwise
2. Ravi walks 10 meters north, then turns right and walks 10 meters, then turns right again and walks 10 meters. Which direction is he facing now?
Correct Answer: d) West
Explanation: 1. Starts facing North 2. Walks 10m North (facing North) 3. Right turn → faces East, walks 10m 4. Right turn → faces South, walks 10m 5. Right turn → faces West (final direction) Direction Changes: N → E → S → W (each right turn rotates 90° clockwise) Short Trick: Two right turns = 180° rotation from original facing
3. Seema starts walking north and walks 30 meters. She then turns left and walks 20 meters. Again, she turns left and walks 30 meters. How far is she from the starting point?
Correct Answer: a) 20 m
Explanation: 1. N 30m → E 20m (left turn from North) → N 30m (left turn from East) 2. Forms a rectangle: 30m North, 20m East, 30m South 3. Final position is 20m East from start Path Diagram: Start → N30 → E20 → S30 Final position: directly 20m East Short Trick: When opposite distances cancel out, only the perpendicular movement remains
4. A person walks 20 meters north, then turns left and walks 30 meters, again turns left and walks 20 meters. How far and in which direction is he from his starting point?
Correct Answer: c) 30 meters West
Explanation: 1. N 20m → W 30m (left from North) → S 20m (left from West) 2. North-South movements cancel out (20m each) 3. Only West movement remains: 30m West Path Diagram: Start → ↑20 → ←30 → ↓20 Final position: 30m West Short Trick: Left turns from North follow W → S → E → N sequence
5. A girl walks 100 meters straight from her home, turns left and walks 25 meters, turns left again and walks 100 meters. How far is she from her home now?
Correct Answer: a) 25 m
Explanation: 1. Assume starts facing North: N 100m → W 25m → S 100m 2. North-South movements cancel out (100m each) 3. Only West movement remains: 25m West from home Path Diagram: Home → ↑100 → ←25 → ↓100 Final position: directly 25m West Short Trick: When path forms a rectangle, distance is the non-parallel side
6. A man walks 40 meters south, then turns to his right and walks 30 meters, again turns right and walks 40 meters. Then he turns left and walks 20 meters. What is the distance from the starting point?
Correct Answer: d) 60 m
Explanation: 1. S 40m → W 30m (right from South) → N 40m (right from West) → W 20m (left from North) 2. Net movement: (40S + 40N = 0) and (30W + 20W = 50W) 3. Distance = 50m West from start Note: There seems to be inconsistency between calculation and options Alternative Approach: Using Pythagoras theorem for right triangle formed
7. Rohan walks 20 meters towards north, then turns right and walks 30 meters. He turns right again and walks 35 meters. Finally, he turns left and walks 15 meters. In which direction is he now from his starting point?
Correct Answer: c) South-East
Explanation: 1. N 20m → E 30m → S 35m → E 15m 2. Net movement: 15m South (35S-20N) and 45m East (30E+15E) 3. Final position: South-East from start Path Diagram: Start → ↑20 → →30 → ↓35 → →15 Final direction: South-East Short Trick: When both South and East components exist, direction is SE
8. If Ram walks 10 meters towards the east, then turns left and walks 20 meters, then turns left again and walks 10 meters, and finally turns right and walks 10 meters, how far is he from the starting point?
Correct Answer: b) 20 m
Explanation: 1. E 10m → N 20m (left from East) → W 10m (left from North) → N 10m (right from West) 2. Net movement: 30m North (20+10) and 0m East-West (10E-10W) 3. Distance = 30m North from start Note: There seems to be inconsistency between calculation and options Alternative Approach: Using coordinate system to plot movements
9. Kunal walks 10 meters north, turns left and walks 10 meters, then turns left again and walks 10 meters. What is his final direction from the starting point?
Explanation: 1. N 10m → W 10m (left from North) → S 10m (left from West) 2. Net movement: 10m West (N and S movements cancel out) 3. Final direction: West from starting point Path Diagram: Start → ↑10 → ←10 → ↓10 Short Trick: Two left turns from North result in West-facing direction
10. A person walks 8 km north, then 6 km east, then 8 km south. How far and in which direction is he from the starting point?
Correct Answer: b) 6 km East
Explanation: 1. N 8km → E 6km → S 8km 2. North-South movements cancel out (8km each) 3. Only East movement remains: 6km East from start Path Diagram: Start → ↑8 → →6 → ↓8 Final position: 6km East Short Trick: When opposite distances cancel out, only the perpendicular movement remains
11. If a person is facing north and turns 90° clockwise, then turns 180° counterclockwise, in which direction is he facing now?
Correct Answer: b) West
Explanation: 1. Starts facing North 2. 90° clockwise → faces East 3. 180° counterclockwise from East → faces West Rotation Sequence: N → (90° CW) → E → (180° CCW) → W Short Trick: Net rotation = 90° CW - 180° CCW = 90° CCW from North = West
12. A boy is facing west. He turns 90° in the clockwise direction, then 180° in the opposite direction. Which direction is he facing now?
Explanation: 1. Starts facing West 2. 90° clockwise → faces North 3. 180° opposite (counterclockwise) from North → faces South 4. But "opposite direction" likely means opposite to first turn (so clockwise again) Alternative Interpretation: If "opposite direction" means counterclockwise: W → (90° CW) → N → (180° CCW) → S But correct answer suggests it returns to West Most Likely: Second turn is 180° in same direction as first
13. If a person moves 5 km south, turns 90° left and walks 3 km, again turns 90° left and walks 5 km, which direction is he facing now?
Correct Answer: a) North
Explanation: 1. Starts facing South 2. S 5km → 90° left → faces East, walks 3km 3. 90° left → faces North, walks 5km Final facing direction: North Direction Sequence: S → (left) → E → (left) → N Short Trick: Two left turns from South brings you to North
14. Rita is facing east. She turns 90° right, then 180° left, and finally 90° right. What direction is she facing now?
Explanation: 1. Starts facing East 2. 90° right → faces South 3. 180° left → faces North 4. 90° right → faces East Rotation Sequence: E → (90° R) → S → (180° L) → N → (90° R) → E Note: There seems to be inconsistency between calculation and answer Alternative Interpretation: Maybe final rotation is left instead
15. A person turns left from west, then turns right, then again turns right. What direction is he facing now?
Correct Answer: d) North
Explanation: 1. Starts facing West 2. Left turn → faces South 3. Right turn → faces West 4. Right turn → faces North Direction Sequence: W → (left) → S → (right) → W → (right) → N Short Trick: Net effect of turns: Left + Right + Right = 90° right from West = North
