Important Concepts and Tips to Solve Direction Sense Questions in Reasoning – Download in PDF:
Dear Readers,  we have given the Important Concepts and Tips to Solve Direction Sense Questions in Reasoning. Candidates who are preparing for the upcoming IBPS PO/ Clerk 2016 examination can make use of distance & direction concepts here.
Distance And Direction
According to geography, there are 8-directions:
·         4-cardinal directions – North, South, East and West
·         4-subsidiary directions – North-East, North-west, South-east, South-west
Â
DIRECTION OFÂ RIGHT TURN: Clockwise
DIRECTION OFÂ LEFT TURN: Anti-clockwise
PYTHAGORAS THEOREM:
This theorem is sometimes needed to find out the distance covered by an individual in the question.
It states that, in a right angled triangle the length of the hypotenuse is equal to the square root of the sum of squares of the other two sides.
Where, H=Hypotenuse
            X=Height
            Y=Base
Therefore, according to the theorem H2 = X2 + Y2
i.e., H= √(X2+ Y2)
IMPORTANT POINTS TO REMEMBER WHILE SOLVING DISTANCE-DIRECTION QUESTION:
–        To know the directions on the plane of paper
–        To sketch out the directions as per the instructions in the question
–        To remember that on the surface of paper
·         The direction of right turn is always in the clockwise direction
·         The direction of left turn is always in the anti-clockwise direction
·         The direction of North is upwards
·         The direction of South is downwards
·         The direction of East is ‘to the right’
·         The direction of West is ‘to the left’
–Â Â Â Â Â Â Â Â To formulate a step by step analysis of directions and distances
–Â Â Â Â Â Â Â Â To find the final direction or the distance between the starting and final point or both
QUESTION:
Ajith walks 10km towards North. From there he walks 6km towards south, then he turns left and walks 3km.
1)Â Â Â Â At what distance is Ajith from the original position?
(a)  7km         (b) 5km         (c) 3km         (d) 4km
2)Â Â Â Â In which direction is Ajith with reference to his starting point?
(a)  North-East         (b) West         (c) South-East         (d) East
Practice Distance & Direction Mock Test
SOLUTION:
·         Take the starting point as ‘A’
·         Now, Ajith walks 10km towards North.
·         The point 10km to the north is taken as ‘B’, AB=10km
·         ‘From there he walks 6km towards south’ i.e., from B Ajith walks 6km downwards again.
·         The point at 6km towards south is taken as ‘C’, such that BC=6km
·         So AC=4km [AB-BC=10-6=4]
·         ‘then he turns left and walks 3km’ i.e., he turns in the anti-clockwise direction from ‘C’ i.e., towards east and walks 3km in the same direction
·         The point 3km in the east is taken as ‘D’, such that CD=3km and D is the end point of the journey of Ajith
1)Â Â Â Â At what distance is Ajith from the original position?
(a)7km         (b) 5km         (c) 3km         (d) 4km
·         Starting point of Ajith is ‘A’
·         End point of Ajith is ‘D’
·         Therefore, the distance of Ajith from the original position is the distance between A and D
·         To find AD, Consider right angle triangle, ACD
AD = hypotenuse = X
AC = 4km
CD = 3km
By Pythagoras theorem, X2 = AC2 + CD2 = 42 + 32 = 16+9
                                          X2 = 25
                                     X = √25 = 5km
·         Therefore, distance at which Ajith is from the original position is 5km
ANSWER:Â (b) 5km

If the question was:
What is the total distance covered by Ajith?
Then the answer will be the sum of all the distances given in the question irrespective of their directions.
i.e., 10km+6km+3km = 19km
Â
2)Â Â Â Â In which direction is Ajith with reference to his starting point?
(a)  North-East         (b) West         (c) South-East         (d) East
·         Present position of Ajith is at ‘D’
·         Now, the direction in which Ajith is with respect to his starting point (A) is asked
·         The answer is the direction in which point ‘D’ is present with respect to point ‘A’, which clearly is towards the North-East direction as per the final figure.
ANSWER:Â (a) North-East
If the question was:
         In which direction is Ajith facing?
·         Then the answer would have been (d) East.
·         Direction faced by point D
