Distance and direction theory, tricks and approach in Reasoning

DISTANCE AND DIRECTIONS- FOR ALL COMPETITIVE EXAMS.

It is one of the important part of the reasoning section and equally important like other topics in verbal reasoning. You will get two to three questions in banking examination while in rest of the exams including CSAT will find one to two questions. 

It is one of the popular topic from examiner point of view.

Direction-

According to the oxford dictionary, the direction means the path, line, or way along which a person or thing is moving, looking, pointing, developing, etc.

    In other words- Geographical / Analytical meaning

It is the information contained in the relative position of one person/ point with respect to another person/ point without knowing distance.

Ø   Direction is the pathway along which an object is moving.  Direction is also the location of a feature based on the position of another feature.

Ø  It may be absolute or may be in the relative form (Relative to some indicated reference.)

 

How we use our mind to assign directions on two dimensional sheet-

Ø          We assume that in our front the direction is North.

Ø       Behind ‘us’ is South.

Ø      To our left is West i.e., our left-hand

Ø      To our Right is East i.e., our right-hand

Ø      Sun rises in the East and sets in the west.

Assumptions Related to Direction Concepts in Problem solving

 Ø  The main direction change undergoes a 90° change in direction. When any person change his/her direction from west to north means taking 90° change  similarly from one basic direction to another basic direction then generally90° changes.

Ø  The change is only 45° change in cardinal direction. For example, there is a 45° change in North to North – East or North to North – West similarly West to North-West or South –west.

Ø The direction of the right turn is always taken clockwise during attempting questions.

Ø  The direction of the left turn is always taken anti-clockwise during attempting questions.

Ø  The problem on the distance covered or the minimal/shortest distance between two points in direction reasoning is solved with  the help of Pythagoras theorem.

Ø  All these distances are along straight lines and between specified points.

Ø  Always draw a line between starting point of travelling and final point, to find shortest distance between two points.

Distance: How we measure distance after showing situation in figure.

Distance is a measurement of the position of one thing with respect to another thing or a reference point.

Ø  Ø  Distance between two points is a measurement of the shortest distance such as the displacement between the two points. The shortest distance between two points may be different from the total distance covered in going from one point to another. 

Ø    Ø Use Pythagoras theorem to find shortest distance by drawing a line between initial and final point.
