In almost all the Objective Type Multiple Choices Examinations a few questions on Direction Sense Test are asked regularly.
In this type of questions a successive follow-up of directions and/or distance is formulated and on the basis of given information you are required to ascertain the final direction with respect to the starting point or the shortest distance between the starting point and the final point. Sometimes both the final direction and the distance covered are asked.
Thus, in this test, the questions consist of a sort of direction and/or distance puzzle. Obviously, such questions are meant to judge the candidate's ability to trace, follow and perceive the direction, described in somewhat complicated language, correctly. In order to solve such questions correctly you must have the knowledge of directions on the plane of a paper. At the same time, it is necessary to sketch out the directions as per the information provided in the question in proper sequence. An error at any point would alter your answer choice .
The diagram given below shows the four main directions (cardinals) and the four subsidiary directions on a plane paper:
Generally right and left turns are frequently employed in the questions in order to confuse the candidates. Remember that examiner does possess the uncanny knack and he/she may confuse you by making verbose statements also. But, there is nothing to panic. You may note that on the surface of paper, the direction of right turn is always clockwise and that of left turn is anticlockwise. Thus,
Now try to comprehend the following deductions:
(i) A person facing towards North, on taking left turn will face towards West and on taking the right turn towards East.
Left turn means anticlockwise rotation and right turn means clockwise rotation. Thus,
(ii) A person facing towards South, on taking left turn will face' towards East and on taking right turn towards West.
(iii) A person facing towards East, on taking left turn will face towards North and on taking right turn towards South.
(iv) A person facing towards West, on taking left turn will face towards South and on taking right turn towards North.
(v) A person facing towards North-West, on taking left turn will face towards South-West and on taking right turn will face towards North-East.
(vi) A person facing towards South-West on taking left turn will face towards South-East and on taking right turn towards North-West.
(vii) A person facing towards South-East, on taking left turn will face towards North-East and on taking right turn towards South-West.
(viii) A person facing towards North-East, on taking left turn will face towards North-West and on taking right turn towards South-East.
In order to determine the distance travelled or the shortest straight distance between the two given points, the Pythagoras formula
2 2 2
h = b + p proves to be helpful.
h = Hypotenuse
p = Perpendicular
b = Base
Now consider the following examples to understand the nature and pattern of the questions on Distance and Direction Test:
Ex.1. Early morning after sunrise, Rajesh was standing in front of his house in such a way that his shadow was falling exacUy behind him. He starts walking straight and walks 5 metres. He turns to his left and walks 3 metres and again turning to his left walks 2 metres. Now in which direction is he from his starting point?
Answer : The shadow of Rajesh was falling exactly behind him. It implies that he was facing towards East.
