'A + B' means 'A is the mother of B',
'A ÷ B' means 'A is the wife of B',
'A & B' means 'A is the brother of B',
'A × B' means 'A is the sister of B',
'A - B' means 'A is the father of B'.
If 'A×Z+P&R÷Q−S', then how is Z related to S?
- AFather's mother
- BMother
- CMother's father
- DMother's mother
Solution & Step-by-step Explanation
Let's break down the expression step by step from left to right:
A×Z→ A is the sister of Z.
Z+P→ Z is the mother of P (Z is female).
P&R→ P is the brother of R.
R÷Q→ R is the wife of Q (R is female, Q is male).
Q−S→ Q is the father of S.
Now let's trace the relation between Z and S:
Q is the father of S.
R is the wife of Q, which means R is the mother of S.
P is the brother of R, so P is the maternal uncle of S.
Z is the mother of P and R, which means Z is the mother of S's mother (R).
Therefore, Z is the Mother's mother (Maternal Grandmother) of S.
A×Z→ A is the sister of Z.
Z+P→ Z is the mother of P (Z is female).
P&R→ P is the brother of R.
R÷Q→ R is the wife of Q (R is female, Q is male).
Q−S→ Q is the father of S.
Now let's trace the relation between Z and S:
Q is the father of S.
R is the wife of Q, which means R is the mother of S.
P is the brother of R, so P is the maternal uncle of S.
Z is the mother of P and R, which means Z is the mother of S's mother (R).
Therefore, Z is the Mother's mother (Maternal Grandmother) of S.
