‘P + Q’ means ‘P is the daughter of Q’.
‘P $ Q’ means ‘P is the husband of Q’.
‘P @ Q’ means ‘P is the brother of Q’.
‘P & Q’ means ‘P is the mother of Q’.
‘P % Q’ means ‘P is the son of Q’.
If ‘W @ S % K $ G & U & T @ R + C’, then which of the following statements is correct?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → G is the maternal grandmother of R
Read the expression one symbol at a time, each time between the two letters on either side of it. The mother of one’s mother is one’s maternal grandmother.
W @ S: W is the brother of S
S % K: S is the son of K
K $ G: K is the husband of G, so G is a female
G & U: G is the mother of U
U & T: U is the mother of T
T @ R: T is the brother of R, so U is also the mother of R
R + C: R is the daughter of C
G is the mother of U, and U is the mother of R, so G is the maternal grandmother of R
Why the other options are incorrect
Option (1) G is the paternal grandfather of R — Incorrect. G is the wife of K, a female, and is related to R through R’s mother U.
Option (3) G is the father of W — Incorrect. G is the wife of K, a female, so she cannot be anyone’s father.
Option (4) G is the father of U — Incorrect. G & U says G is the mother of U.
