A river flows west to east and on the way turns left and goes in a semicircle round hillock, and then turns left at right angle. In what direction is the river finally flowing ?

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

Answer: B

The river finally flows east.

Trace each turn:

  • It starts flowing east.
  • A left turn makes it flow north.
  • Going round a hillock in a semicircle reverses its direction, so it now flows south.
  • A left turn at a right angle from south points it east.

North is the direction after the first turn only, and west would follow from a right turn at the end. South is the direction before the final turn.
