In a certain code language,
'A + B' means 'A is the mother of B',
'A - B' means 'A is the father of B',
'A x B' means 'A is the brother of B' and
'A & B' means 'A is the sister of B'.
How is Q related to N if N-DxP + Q & C?
Understanding the Code Language
The problem provides a specific code language to represent family relationships. It's important to understand each rule clearly before applying it to the given expression.
| Code | Meaning |
| A + B | A is the mother of B |
| A - B | A is the father of B |
| A x B | A is the brother of B |
| A & B | A is the sister of B |
Decoding the Family Relationship Expression
The core task is to decipher the relationship puzzle presented by the expression: N - D x P + Q & C. We will break this down step-by-step, applying the defined rules.
- Step 1: Analyze
N - D
Using the rule 'A - B' means 'A is the father of B', we deduce that N is the father of D. This tells us N is male. - Step 2: Analyze
D x P
Using the rule 'A x B' means 'A is the brother of B', we find that D is the brother of P. Since D is male, P is D's sibling. As established in Step 1, N is the father of D. Therefore, N is also the father of P. - Step 3: Analyze
P + Q
Using the rule 'A + B' means 'A is the mother of B', we determine that P is the mother of Q. This confirms that P is female. Since N is the father of P (from Step 2), and P is the mother of Q, it means P is N's daughter. Consequently, N is the father of his daughter, P. - Step 4: Analyze
Q & C
Using the rule 'A & B' means 'A is the sister of B', we learn that Q is the sister of C. This confirms that Q is female. While this detail is useful for Q's gender, it doesn't change the established relationship between N and Q.
Determining Q's Relation to N
Now, let's combine the information derived from the steps above to understand the connection between Q and N:
- From Step 3, we established that N is the father of P.
- From Step 3, we also know that P is the mother of Q.
Putting these together, N is the father of Q's mother. This makes N the maternal grandfather of Q.
The question asks specifically how Q is related to N. Since N is the maternal grandfather, Q is his grandchild.
To be more precise, N's daughter is P, and P is Q's mother. Therefore, Q is the daughter of N's daughter.
This relationship signifies that Q is N's granddaughter. The option "Daughter's daughter" accurately describes this granddaughter relationship from N's perspective.
