Radha walks 14 km towards north. She turns right and walks 22 km. She turns right and walks 24 km. She turns left and walks 26 km. She finally rotates by an angle of 90 degrees in anti-clockwise direction and walks 24 km. How far and in which direction is her starting point from the finishing point?
  • A76 km, south-east
  • B76 km, north-west
  • C50 km, south-west
  • D50 km, north-west
Correct answer: C

Explanation

Radha ends up 48 km east and 14 km north of the start (14 N, then 22 E, 24 S, 26 E, 24 N). The distance is √(48² + 14²) = 50 km, and the start lies to her south-west.
