Direction is the most puzzling concept in reasoning studies. Often out of 10, almost 5 questions student attempt wrong, just due to impractical ways they apply. With direction, rotation additionally makes the puzzle harder to crack.





North, South, East, West start revolves in your puzzling mind and left with no option except picking any answer which is completely a matter of chance. DO NOT DO IT! As I have simplest & practical ways to solve the Direction- I. NO Trapping! No Difficulty! Just an easy way to get all done in few seconds.

Let’s see how….
Direction-I
These are names of directions in our schooling we read and known with. However, rotating the directions clockwise and anticlockwise is the biggest question of the time. Do you know anything about it? See here

Clockwise Rotation:The direction which usually clock follows i.e. Right to left.



Direction CLOCKWISE


Anticlockwise Rotation: The direction opposite to Clockwise i.e. left to Right



Direction Anti-CLOCKWISE


Starting with Puzzles

Problem1: From his house, A person went 10kms to the North. Then he turned to his left and walks 5kms. He again turned to left and walks 10 kms. How much distance covered from his house and In which direction is he from his house.

Solution:


Step1: From his house, A person went 10kms to the North.
Direction Problem 1


Step2: Then he turned to his left and walks 5kms.



Step3: He again turned to left and walks 10 kms. Applying clockwise rotation, left will come down.



Step 4: How much he distance covered and in which direction is he from his house.

Right now he is in West of his house and the distance between house and West is 5km.
Problem2: A person walks 4km towards south. Then he turned east and walks 3 km. At what distance he is from starting point?

Solution:


Step1:A person walks 4 km towards south

Direction Problem 2


Step2: He turned east and walks 3 km



Step 3: At what distance he is from starting point?



From Starting point i.e. 0 the distance can be calculated by Pythagoras theorem(Find one side of Triangle when other sides given)



The formula is H2 = P2 + B2

Putting values H2 = 42 + 32 = 25

Hypotenuse= 5KM = Distance from Starting point
Problem3: Neena Moved 7km towards east, then turned to her left and 5km. Then she turned to her left and moved 7km.How far she from starting point?

Solution:

Step 1:
Neena Moved 7km towards east

Direction Problem 3


Step 2: Then turned to her left and 5km, Going clockwise left will go up towards North.



Step 3: Then she turned to her left and moved 7km, left will fo left as we ae in clockwise rotation



The distance from starting point and now where he is 5km.
Problem4: Steve Traveled from police-post straight for 400m.He turned left and traveled 500m straight after which he turned left again and travelled for 400m straight. He then turned to right and walked for another 600m straight. How he far from police post?

Solution:

Step1:
Steve walks 10km south of his house

Direction Problem 4


Step2: He turned left and traveled 500m straight.In Clockwise rotation, left will come left



Step3: He turned left again and travelled for 400m straight. According to clockwise rotation, left will come down.



Step4:He then turned to right and walked for another 600m straight.Now he is going into theAnti-clockwise rotation, now his right will come left.



Step5: How he far from police post?

Adding 600 + 500 =1100 m or 11km is the actual distance from Police Post.
