Tips and Tricks for Directional Senses
Directions problems questioned in the exam are based on 2 principles-
- Distance
- Direction
There are mainly four directions – East, West, North & South and 4 types of cardinal directions such as North East, North West, South East, and South West as represented below
Left and Right side Movements
- If a person is looking at northside, on making a move towards left will face to west direction and on making a move towards right will face to eastside.
- If a person is looking at west direction, on making a move towards left will face to southside and on making a move towards right will face to north.
- If a person is looking to east, on making a move towards left will face to north and on making a move towards right will face to south.
- If a person is looking to south, on making a move towards left will face east and on making a move towards right will face to west.
Hence, the above facts can be sum up as:
Every time an individual moves to her/his left side, he/she will move in the direction of anti- clockwise.
Every time an individual moves to her/his right side, he/she will move in the direction of clockwise.Message: if a question says to move towards left side or right side, we solve the problem by assuming the movement at an angle of 90 degrees.
