Understanding Blood Relations Coding

In blood relations problems involving codes, each symbol represents a specific relationship. We need to decode the given expression using the provided information and then determine the relationships between the individuals.

The given information defines the following relationships:

• ‘A + B’ means ‘A is the brother of B’.
• ‘A = B’ means ‘A is the daughter of B’.
• ‘A @ B’ means “A is the wife of B’.

The expression we need to analyze is ‘U + Y = T @ G’.

Decoding the Expression U + Y = T @ G

Let's break down the expression into smaller parts based on the symbols:

1. U + Y: According to the first rule, 'A + B' means 'A is the brother of B'. So, 'U + Y' means 'U is the brother of Y'. This tells us U is male.
2. Y = T: According to the second rule, 'A = B' means 'A is the daughter of B'. So, 'Y = T' means 'Y is the daughter of T'. This tells us Y is female and T is her parent.
3. T @ G: According to the third rule, 'A @ B' means 'A is the wife of B'. So, 'T @ G' means 'T is the wife of G'. This tells us T is female and G is male, and they are married.

Now, let's combine these relationships to understand the family structure:

• From (2), Y is the daughter of T.
• From (3), T is the wife of G. This means G is the husband of T.
• Since Y is the daughter of T and T is married to G, G must be the other parent of Y. Therefore, G is the father of Y.
• From (1), U is the brother of Y.
• Since U and Y are siblings, and their parents are T (mother) and G (father), U's parents must also be T and G.
• Therefore, U is the son of T and G.

Based on the expression ‘U + Y = T @ G’, we have established the following key relationships:

• U is the brother of Y.
• Y is the daughter of T.
• T is the wife of G.
• Consequently, G is the father of Y, T is the mother of Y, G is the father of U, and T is the mother of U.

Evaluating the Given Statements

Now let's examine each statement provided in the options based on our derived relationships:

1. G is the father of U. We derived that U is the son of G (and T). This statement matches our finding.
2. T is the sister of U. We derived that T is the mother of U. A mother is not a sister. This statement is incorrect.
3. G is the paternal uncle of Y. We derived that G is the father of Y. A paternal uncle is the brother of the father. A father is not a paternal uncle of his own child. This statement is incorrect.
4. T is the maternal aunt of U. We derived that T is the mother of U. A maternal aunt is the sister of the mother. A mother is not a maternal aunt of her own child. This statement is incorrect.

Based on the evaluation, only the first statement is correct.

Additional Information: Solving Blood Relations

Solving blood relations problems, especially those with coded relationships, requires careful step-by-step analysis. Here are some tips:

• Break down the complex expression into smaller, manageable parts based on the symbols.
• Decode each part to identify the direct relationship between the two individuals involved in that segment.
• Use the decoded relationships to build a family tree or list the relationships between all individuals mentioned in the expression. Determine the gender of individuals if possible.
• Once the family structure is clear, evaluate each option provided in the question against the derived relationships.
• Be careful with terms like 'paternal' (related to the father's side) and 'maternal' (related to the mother's side).

Practice with different types of blood relations puzzles, including those with coded language, to improve speed and accuracy.
