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, how is R related to Q if 'P × Q ÷ T + S - R × V'?
- ASon's daughter
- BMother's father
- CDaughter's daughter
- DMother's mother
Solution & Step-by-step Explanation
Let's decode the given relationship tree expression step-by-step:
P × Q: P is the wife of Q (P
(−)
⇔Q
(+)
).
Q ÷ T: Q is the father of T (T is a child of Q and P).
T + S: T is the mother of S (T
(−)
is a parent of S).
S - R: S is the brother of R (S
(+)
−R, both are children of T).
R × V: R is the wife of V (R
(−)
⇔V
(+)
).
Now, let's analyze how R is related to Q:
T is the daughter of Q.
R is the daughter of T (since R is female and a sibling of S).
Therefore, R is Q's daughter's daughter (Daughter's daughter).
P × Q: P is the wife of Q (P
(−)
⇔Q
(+)
).
Q ÷ T: Q is the father of T (T is a child of Q and P).
T + S: T is the mother of S (T
(−)
is a parent of S).
S - R: S is the brother of R (S
(+)
−R, both are children of T).
R × V: R is the wife of V (R
(−)
⇔V
(+)
).
Now, let's analyze how R is related to Q:
T is the daughter of Q.
R is the daughter of T (since R is female and a sibling of S).
Therefore, R is Q's daughter's daughter (Daughter's daughter).
