A boy starts from his home. After walking 10 km towards north he turns right and walks for 5 km. Again he turns right and walks for 15 km. In which direction is he from his home :

ASouth-East

BSouth-West

CNorth-East

DNorth-West

Answer:

A. South-East

Read Explanation:

The boy is in the South-East direction from his home.

Start: He begins at his home, which we can consider as the starting point $(0,0)$ .
First Move: He walks 10 km North.
Second Move: Turning right faces him East, where he walks 5 km East.
Third Move: Turning right again faces him South, where he walks 15 km South.

Since he walked 10 km North and then 15 km South, he ends up 5 km South of his original starting latitude. Combined with his 5 km East movement, his final position places him south and east of his home.
