Each of the following questions is based on the following information:
A # B means B is at 1 metre to the right of A.
A $ B means B is at 1 metre to the North of A.
A * B means B is at 1 metre to the left of A.
A @ B means B is at 1 metre to the south of A.
In each question first person from the left is facing North.
According to M # N $ T, T is in which direction with respect to M?
- A.
North-West
- B.
North-East
- C.
South-West
- D.
South-East
Show answer & explanation
Correct answer: B
Concept: Each symbol in this code defines one unit displacement along a compass axis — "#" = 1 m East, "*" = 1 m West, "$" = 1 m North, "@" = 1 m South. To find the net direction between any two points in a chain, add up the East-West and North-South displacements separately, then read the resulting direction from the sign of each component.
Application
Place M at the origin, with East-West as the horizontal axis and North-South as the vertical axis.
M # N: N lies 1 m East of M.
N $ T: T lies 1 m North of N — so, relative to M, T is displaced 1 m East and 1 m North overall.
Cross-check:
Since T's horizontal displacement from M is Eastward (positive) and its vertical displacement is Northward (positive), both components point away from M into the same quadrant — the North-East direction.
