- AGrandmother
- BMother-in-law
- CMother's sister
- DMother's father
Solution & Step-by-step Explanation
Let's decode the expression P&T@R#S@W from left to right:
P&T→P is the mother of T.
T@R→T is the husband of R (so R is female).
R#S→R is the daughter of S.
S@W→S is the husband of W (so W is female and S is male).
From (3) and (4), S and W are the parents of R (S is the father, W is the mother).
Since R is married to T, W is the mother of T's wife, which means W is the Mother-in-law of T.
P&T→P is the mother of T.
T@R→T is the husband of R (so R is female).
R#S→R is the daughter of S.
S@W→S is the husband of W (so W is female and S is male).
From (3) and (4), S and W are the parents of R (S is the father, W is the mother).
Since R is married to T, W is the mother of T's wife, which means W is the Mother-in-law of T.
