In a certain code language,
'A + B' means 'A is the mother of B',
'A - B' means 'A is the brother of B',
'A × B' means 'A is the wife of B',
'A ÷ B' means 'A is the father of B'.
Based on the above information, how is Q related to S if ‘P + Q ÷ R × S − T'?
- AWife's sister
- BWife's mother
- CWife's brother
- DWife's father
Solution & Step-by-step Explanation
Let's decode the given expression step-by-step from left to right:
P+Q: P is the mother of Q.
Q÷R: Q is the father of R (Q is Male).
R×S: R is the wife of S (R is Female, S is Male).
S−T: S is the brother of T.
From steps 2 and 3:
Q is the father of R.
R is married to S (S is R's husband).
Therefore, Q is the father of S's wife, which means Q is the Wife's father of S.
P+Q: P is the mother of Q.
Q÷R: Q is the father of R (Q is Male).
R×S: R is the wife of S (R is Female, S is Male).
S−T: S is the brother of T.
From steps 2 and 3:
Q is the father of R.
R is married to S (S is R's husband).
Therefore, Q is the father of S's wife, which means Q is the Wife's father of S.
