Correct Answer: 13 km towards South-East


Solution : Firstly, we will draw the diagram as per the given instructions –

From the above diagram, it is clear that Rahul is in the South-East direction from his starting point.

For the shortest distance (AB) between the starting point and the endpoint, use Pythagoras theorem,
⇒ (AC) 2 + (BC) 2 = (AB) 2
⇒ (12) 2 + (5) 2 = (AB) 2
⇒ 144 + 25 = (AB) 2
⇒ (AB) 2 = 169
⇒ AB = 13 km

Thus, Rahul is towards the South-East direction and 13 km away from the starting point. Hence, the fourth option is correct.
