Direction-notation decoding: Find S's direction relative to Q from the symbolic expression.
Notation: A × B ⇒ A is south of B; A + B ⇒ A is north of B; A % B ⇒ A is east of B; A − B ⇒ A is west of B.
Expression: P % Q + R − S
Task: Determine the direction of S with respect to Q.
Difficulty: Medium
Correct Answer: South-East
Explanation:
Decode each relation
P % Q ⇒ P is east of Q (not directly needed for S vs Q).
Q + R ⇒ Q is north of R ⇒ R is south of Q.
R − S ⇒ R is west of S ⇒ S is east of R.
CombineR is south of Q and S is east of R ⇒ S lies south-east of Q.
