RAS question
Seema starts from her home, walks 5 km towards East, turns left and walks 3 km, turns left again and walks 5 km. In which direction is she now facing?
Correct answer: (A) West.
After starting east and making two left turns, Seema is facing west.
Explanation
Seema begins by facing east and walks 5 km in that direction. A left turn from east puts her facing north, so her next 3 km are northward. She then turns left again; from north, a left turn points west. The final 5 km only changes her position, not her facing direction, so she is now facing west. This follows the standard cardinal-direction frame used in map and compass work: north, east, south and west are the four cardinal points, with east at 90 degrees and west at 270 degrees. Tracking the facing direction after each turn is enough here; the distances help describe the path but do not change the left-turn logic.
Why the other options are wrong
- (B) East is only Seema's initial facing direction; after two left turns her direction has rotated away from east to west.
- (C) North is her direction after the first left turn, but the second left turn changes her facing direction from north to west.
- (D) South would require a right turn from east or an additional left turn sequence, neither of which occurs in the given path.
Concept
This tests direction sense in Reasoning and Mental Ability: the candidate must update orientation after each turn rather than only plot distance. Such questions recur in RAS because they check quick spatial reasoning using the cardinal directions.
