8th Class Mental Ability Direction Sense Test Direction Sense Test

Main Directions:

There are four main directions viz. East, West, North and South.

East and West as well as North and South are opposite to each other as shown below.

The sun always rises in the East and sets in the West.

Four Other Directions:

There are four other directions which lie in between the four main directions.

These are: North-East (N-E), North-West (N-W), South-East (S-E), South-West (S-W)

Two Cyclic Directions:

There are two cyclic directions namely clockwise and anticlockwise.

The direction in which the hands of a clock move is called clockwise direction while its opposite direction is called anticlockwise direction as shown below.

EXAMPLE

Priya goes 12 km towards North from a fixed point and then she goes 8 km towards South from there. In the end she goes 3 km towards East. How far and in which direction is she from her starting point?

(a) 5 km, North-East        (b) 5 km. West     

(c) 7 km, West                   (d) 7 km. East

Explanation (a):

Let Priya starts from the point P and reach Q.

Then from Q, she returns to R. At the end she goes from R to S.

Clearly, Priya is finally at S.

S is in North-East of P.

In APRS, ZPRS =          

Using Pythagoras theorem, we get

Thus Priya is 5 km away from the initial point in North-East of the initial point.

So the correct option is (a).
