Question

B is the 100m North East of C.if A is 100m North West of C ,A is in which direction of B

Answer 1

                North
                   |
                   |
West - - - - - - - - - - - - - - - East
                   |
                   |
                South
B is North East of C by 100m
A is North West of C by 100m
If we tally the position
               North
            A     |        B
                   |
West - - - - - - - C - - - - - - - - East
                   |
                   |
                South
Hence , A is Due west of B and vice versa

Answer 2

Let us consider that C is at the center of a point. 

As given in the question, B is 100 m Northeast to C. So, if C is facing in the North direction, then B should be onto the front right corner side since it is at the Northeast direction.

Since A is 100 m Northwest to C, it should be on the front left corner if it is assumed to be facing in the north direction.

So, A will lie on the right side of B and B will be on the left side of A.

Therefore, by relating these positions to the normal cardinal directions, we can say that A is on the west of B. Similarly, B will be on the east of A.
