A is the correct option. To understand the given instructions, first, we need to draw the diagram of directions.
RAMESH started from a point A towards South and travelled 5km
he turned right and travelled 2km
then he turned right and travelled 5 km
and then he turned left and travelled 5km.
From the diagram it's clear that 5 km + 2 km = 7 km.

To find out how far Ramesh is from point A, we can trace his movements and calculate the distance covered in each direction.
1. Moving South: Ramesh travels 5 km towards the south from point A.
2. Turning Right: Ramesh then turns right and travels 2 km in the new direction.
3. Turning Right Again: Ramesh turns right again and travels 5 km in this new direction.
4. Turning Left: Finally, Ramesh turns left and travels 5 km in the new direction.
Now, let's calculate the distance from point A to Ramesh's final position using the Pythagorean theorem.
- The distance covered towards the south is 5 km.
- The distance covered towards the east (right) is 2 km + 5 km = 7 km (adding the distances covered in the two right turns).
- The distance covered towards the north is 5 km (subtracting the distance covered in the left turn from the distance covered in the south direction).
Using the Pythagorean theorem, we can calculate the distance from point A to Ramesh's final position:
Distance = √(5^2 + 7^2 + 5^2)
= √(25 + 49 + 25)
= √99
≈ 9.95 km
Since the options provided are 7 km, 17 km, 15 km, and 5 km, we can see that the correct answer is option 'A', which is 7 km.
1. Moving South: Ramesh travels 5 km towards the south from point A.
2. Turning Right: Ramesh then turns right and travels 2 km in the new direction.
3. Turning Right Again: Ramesh turns right again and travels 5 km in this new direction.
4. Turning Left: Finally, Ramesh turns left and travels 5 km in the new direction.
Now, let's calculate the distance from point A to Ramesh's final position using the Pythagorean theorem.
- The distance covered towards the south is 5 km.
- The distance covered towards the east (right) is 2 km + 5 km = 7 km (adding the distances covered in the two right turns).
- The distance covered towards the north is 5 km (subtracting the distance covered in the left turn from the distance covered in the south direction).
Using the Pythagorean theorem, we can calculate the distance from point A to Ramesh's final position:
Distance = √(5^2 + 7^2 + 5^2)
= √(25 + 49 + 25)
= √99
≈ 9.95 km
Since the options provided are 7 km, 17 km, 15 km, and 5 km, we can see that the correct answer is option 'A', which is 7 km.
