All questions of Direction Sense Test for Class 7 Exam

Solution:

Given,
A man walks 15 km towards South and then turns to the right. After walking 7 km he turns to the left and walks 9 km.

Let us represent the above movements on a diagram:

Starting point -> 15 km towards South -> right turn -> 7 km -> left turn -> 9 km

From the above diagram, we can see that the man is facing towards the South-West direction.

Therefore, the correct answer is option D) South-West.

To solve this problem, we need to visualize Rakesh's movements on a coordinate plane. Let's break down his movements step by step:

1. Rakesh walks 50 km towards East.
- Starting from the origin (0,0), he moves 50 km to the right in the positive x-direction. His new position is (50,0).

2. Rakesh turns right and walks 15 km.
- After turning right, he walks 15 km in the positive y-direction. His new position is (50,15).

3. Rakesh turns right again and walks 50 km.
- Now, he turns right again and walks 50 km in the negative x-direction. His new position is (0,15).

4. Rakesh moves 10 km after turning right.
- Finally, he moves 10 km in the negative y-direction. His new position is (0,5).

Now, we can use the distance formula to find the distance between his final position and the origin:

Distance = √((x2 - x1)^2 + (y2 - y1)^2)

Plugging in the values, we get:

Distance = √((0 - 0)^2 + (5 - 0)^2)
Distance = √(0 + 25)
Distance = √25
Distance = 5 km

Therefore, Rakesh is 5 km away from his original position. Hence, the correct answer is option D.

East

Degrees to her right and walked for some distance. She then turned left again and walked straight. In which direction is she now headed?

The girl is now headed towards the north.

Explanation:
Ronak turns left, then right, then right again, and finally left. This means he has made a complete turn of 360 degrees in a clockwise direction. Therefore, his final direction is to the right of his starting direction.

Directional analysis:

Starting direction: Facing the sun (which is in the west in the afternoon)
First turn: Left (towards the south)
Second turn: Right (towards the west)
Third turn: Right again (towards the north)
Fourth turn: Left (towards the west)

Conclusion:

After making these turns, Ronak is facing towards the west, which is to his right of his starting direction. Therefore, the correct answer is option B, which is West.

Explanation:

Given transformations:
- South-East becomes North
- North-East becomes West
- West becomes South

Logical analysis:
- South-East is located to the bottom right of a map.
- North-East is located to the top right of a map.
- West is located to the left of a map.

Applying the given transformations:
- South-East becomes North: If South-East becomes North, then North-East will become West.
- North-East becomes West: Following the same logic, West will become South.
- Therefore, West will become South-East.
Therefore, West will become South-East when the given transformations are applied.

Golu's Directions and Distances:

1. Southwards: Golu walks 1 km in the south direction.
2. Left Turn: After walking 1 km south, Golu takes a left turn.
3. Straight: Golu walks straight for 6 km.
4. Left Turn: After walking for 6 km, Golu takes a left turn.
5. Straight: Golu walks straight for 5 km.
6. Right Turn: After walking for 5 km, Golu takes a right turn.
7. Straight: Golu walks straight for 5 km.

Final Direction:

Based on the given information, we can determine Golu's final direction from the starting point.

1. Southwards: Golu initially walks 1 km southwards.
2. Left Turn: After the left turn, Golu is now facing eastwards.
3. Straight: Golu walks straight for 6 km, still facing eastwards.
4. Left Turn: After the second left turn, Golu is now facing northwards.
5. Straight: Golu walks straight for 5 km, still facing northwards.
6. Right Turn: After the right turn, Golu is now facing eastwards.
7. Straight: Golu walks straight for 5 km from this point.

Therefore, Golu is now in the east direction from the starting point.

Explanation:

To determine the final direction, we need to analyze the turns Golu takes and the distances he walks in each direction.

Golu starts by walking 1 km southwards. Then, he takes a left turn and walks straight for 6 km. This means he is now facing eastwards. After that, he takes another left turn and walks straight for 5 km. Now, he is facing northwards.

Finally, Golu takes a right turn and walks straight for 5 km. This means he has made a complete turn and is now facing eastwards again. From this point, he walks straight for 5 km.

Therefore, Golu's final direction from the starting point is eastwards.

Tatii

Stood facing north, then Tulsi would be facing south.

Analyzing the problem:
To solve this problem, we need to carefully analyze the given information and the directions mentioned. Let's break it down step by step:

1. Ankit starts from his house and walks Westwards.
2. He takes a left turn.
3. He takes a right turn.

Understanding the directions:
To understand the directions, let's consider the four main cardinal directions:

- North (N)
- South (S)
- East (E)
- West (W)

Visualizing the directions:
To visualize the directions, let's consider a map:

```
N
|
W--|--E
|
S
```

Step by step analysis:
1. Ankit starts from his house and walks Westwards.
- This means Ankit is initially moving towards the West direction (W).

2. He takes a left turn.
- A left turn from the West direction (W) would lead Ankit towards the South direction (S).

3. He takes a right turn.
- A right turn from the South direction (S) would lead Ankit towards the West direction (W).

Final direction:
After taking a left turn and a right turn, Ankit is now walking towards the West direction (W).

Therefore, the correct answer is option 'C' - West.

Summary:
Ankit starts walking Westwards, takes a left turn towards the South direction, and then takes a right turn towards the West direction. So, he is currently walking towards the West direction (W).
