A & B means 'A is the brother of B'.
A # B means 'A is the wife of B'.
A ^ B means 'A is the mother of B'.
A + B means 'A is the father of B'.
If U + Q ^ R @ N & C ^ I @ J # A, then which of the following statements is NOT correct?
Decoding Relationship Symbols
First, let's understand the meaning of each symbol:
- $+$ means 'is the father of'
- $^$ means 'is the mother of'
- $@$ means 'is the sister of'
- $&$ means 'is the brother of'
- $#$ means 'is the wife of'
Analyzing the Relationship String
We are given the string: $U + Q ^ R @ N & C ^ I @ J # A$. Let's break it down step-by-step to build the family tree:
- $U + Q$: U is the father of Q.
- $Q ^ R$: Q is the mother of R. (So, U is the father of Q, and Q is the mother of R).
- $R @ N$: R is the sister of N. (So, Q is the mother of both R and N. R and N are siblings).
- $N & C$: N is the brother of C. (So, Q is the mother of R, N, and C. R, N, and C are siblings).
- $C ^ I$: C is the mother of I. (So, C is a parent of I).
- $I @ J$: I is the sister of J. (So, C is the mother of both I and J. I and J are siblings).
- $J # A$: J is the wife of A. (So, A is the husband of J).
Constructing the Family Tree
From the breakdown, we can infer the following:
- U and Q are the parents of R, N, and C.
- Q is the mother of R, N, and C. Therefore, U is the maternal grandfather of R, N, and C.
- C is the mother of I and J.
- J is the wife of A. This means A is the son-in-law of C.
- Since C is the mother of I and J ($C ^ I$), C is female. As Q is the mother of C, C is the daughter of Q.
- Since R is the sister of N ($R @ N$), R is female. Since N is the brother of C ($N & C$), N is male.
Evaluating the Options
Now, let's check each statement based on our family tree:
- Option 1: A is the son of C.
- We know J is the wife of A, and C is the mother of J.
- This makes A the son-in-law of C, not the son.
- This statement is NOT correct.
- Option 2: Q is the mother of N.
- From step 3 and 4 of the analysis, Q is the mother of R, N, and C.
- This statement is correct.
- Option 3: U is the maternal grandfather of R.
- U is the father of Q (step 1), and Q is the mother of R (step 2).
- Therefore, U is the maternal grandfather of R.
- This statement is correct.
- Option 4: C is the daughter of Q.
- From step 4, Q is the mother of C.
- From step 5, C is the mother of I, meaning C is female.
- Since Q is the mother of C and C is female, C is the daughter of Q.
- This statement is correct.
Conclusion
The statement that is NOT correct is "A is the son of C."
