Q:

Sumanth walks 200 feet straight from his house, which is facing north and then he walks 100 feet in reverse direction.Further he takes a left turn and walks 300 yards.In Which direction is Sumanth now from his original position?

A) South-East	B) North-East
C) South-West	D) North-West

Answer & Explanation Answer: B) North-East

Explanation:

Starting From his house, Sumanth walks 200 feet straight towards North; we can write it as $N_{200}$ . Similarly, the other distances and directions can be considered and written as follows : (Notice that he covers 300 yards towards East; one yard = 3 feet and hence 300 yards = 900 feet)

$N_{200} S_{100} E_{900}$ Adding all south and all North distances and finding the net result, and also adding all East and all West distances and finding the net result, this can further be summarized as : $N_{100} E_{900}$

Thus, the direction from his original position is North-East.
