Given information:
- Radha moves towards South-East a distance of 7 km,
- then she moves towards West and travels a distance of 14 km,
- From here she moves towards North-West a distance of 7 km,
- and finally she moves a distance of 4 km towards east.
To find: How far is she now from the starting point?
Solution:
Let's assume that the starting point is O and the position of Radha after each movement is shown as A, B, C, and D as follows:
O ----- A (7 km SE) ----- B (14 km W) ----- C (7 km NW) ----- D (4 km E)
We need to find the distance OD, which is the final position of Radha from the starting point.
Now, let's draw a diagram to visualize the movements of Radha:
```

W ---- O ---- E
|
S
```
From the diagram, we can see that:
- The movement towards South-East is a combination of South and East directions.
- The movement towards North-West is a combination of North and West directions.
So, we can break down the movements of Radha as follows:
- Movement 1: 7 km towards South
- Movement 2: 7 km towards East
- Movement 3: 14 km towards West
- Movement 4: 7 km towards North
- Movement 5: 4 km towards East
Now, we can calculate the final position of Radha as follows:
- The movements towards South and North cancel out each other, so the net movement in the North-South direction is 0 km.
- The movements towards East and West cancel out each other, so the net movement in the East-West direction is 7 km (i.e., 7 km towards East).
- Therefore, the final position of Radha is 7 km towards East from the starting point.
Hence, the correct answer is option (c) 10 km.
- Radha moves towards South-East a distance of 7 km,
- then she moves towards West and travels a distance of 14 km,
- From here she moves towards North-West a distance of 7 km,
- and finally she moves a distance of 4 km towards east.
