Similarly, Amit walks 2 kms North and turns to west and walks 3 kms and finally turns to North, walks 4 kms and meets Arun at point 'C'. What is the distance between Arun and Amit's starting points?

 A) 5 km B) 8 km C) 11 km D) 13 km

PQ + RC + ST = 3 + 5 + 3 = 11 kms.

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

Explanation:

Starting From his house, Sumanth walks 200 feet straight towards Noarth; we can write it as $\inline N_{200}$. 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)

$\inline N_{200}S_{100}E_{900}$ 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 : $\inline N_{100}E_{900}$

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

Q:

A man is facing north-west. He turns $\inline 90^{o}$ in the clockwise direction, then $\inline 180^{o}$ in the anticlockwise direction and then another $\inline 90^{o}$ in the same direction. Which direction is he facing now?

 A) South B) South-west C) South-east D) East

As shown in fig. the man initially faces in the direction OP. On moving $\inline 90^{o}$ clockwise, he faces in the direction OX. On further moving $\inline 180^{o}$ anticlockwise, he faces in the direction OY. Finally, on moving $\inline 90^{o}$ anticlockwise, he faces in the direction OZ, which is South-east
