A man walks 5 km toward south and then turns to the right. After walking 3 km he turns to the left and walks 4 km. And then he goes back 10 km straight. Now in which direction is he from the starting place ?

  • A.South-East
  • B.North-West
  • C.South
  • D.West

Answer: B

Correct answer: North-West

Track the turns one at a time. He starts south for 5 km, turns right to face west and covers 3 km, turns left to face south again for 4 km, and then goes back - reversing his heading to north - for 10 km. Southward he has gone \( 5+4=9 \) km and northward 10 km, so he ends 1 km north of his start and 3 km west of it. That puts him north-west of the starting place.
