Show answer & explanation
Correct answer: D
In a direction-coding problem, each symbol is a fixed instruction that moves the next person one unit along a map direction. Resolve a chain by applying the symbols in order, treating the map as a grid where North is up, South is down, East is right and West is left for a person facing North. The final direction is read from the first person to the last.
"X @ B": the "@" symbol means 1 metre to the south, so B is placed 1 metre directly south of X.
"B * P": the "*" symbol means 1 metre to the left; for a person facing North, left is West, so P is placed 1 metre west of B.
Combine the two moves from X: 1 metre south, then 1 metre west.
A point that is both south and west of the start lies in the south-west quadrant, on the diagonal between due-south and due-west. So P is south-west of X.
