Solving the Blood Relation Puzzle

This question asks us to determine the relationship between P and N based on a given expression and a set of coded relationships. We need to decode the expression step-by-step using the provided rules.

Understanding the Code

Let's first understand what each symbol represents:

Now, let's break down the given expression: P + M $\div$ Q $\times$ N $\times$ T - U

Step-by-Step Decoding of the Expression

1. P + M: According to the rule, 'A + B' means 'A is the father of B'. So, P + M means P is the father of M. This tells us P is male.
2. M $\div$ Q: According to the rule, 'A $\div$ B' means 'A is the sister of B'. So, M $\div$ Q means M is the sister of Q. This tells us M is female. Since P is the father of M, and M is the sister of Q, P is also the father of Q. M and Q are siblings.
3. Q $\times$ N: According to the rule, 'A $\times$ B' means 'A is the daughter of B'. So, Q $\times$ N means Q is the daughter of N. This tells us Q is female. We already know P is the father of Q. If Q is the daughter of P (father) and also the daughter of N, then N must be the mother of Q. This implies that P and N are married, with P being the husband and N being the wife.
4. N $\times$ T: According to the rule, 'A $\times$ B' means 'A is the daughter of B'. So, N $\times$ T means N is the daughter of T. This confirms N is female, which aligns with our previous deduction that N is the mother of Q and potentially P's wife.
5. T - U: According to the rule, 'A - B' means 'A is the husband of B'. So, T - U means T is the husband of U. This tells us T is male and U is female. This step provides information about N's parents but isn't directly needed to find the relationship between P and N.

Determining the Relationship between P and N

From the decoding steps, we found that:

• P is the father of Q.
• Q is the daughter of N.

For Q to be the daughter of both P and N, P and N must be the parents of Q. Since P is the father, N must be the mother. This means P and N are a married couple.

Therefore, P is the husband of N.

Checking the Options

Let's compare our derived relationship with the given options:

1. Son: Incorrect. P is N's husband.
2. Husband: Correct. Our deduction shows P is the husband of N.
3. Paternal Uncle: Incorrect. P is N's husband, not her brother or brother-in-law.
4. Brother: Incorrect. P is N's husband.

Based on the decoded relationships, P is the husband of N.

Additional Information on Blood Relation Puzzles

Blood relation questions test your ability to understand and trace family relationships. Here are some tips for solving them:

• Draw a family tree: Visualizing the relationships can make it easier to solve complex puzzles. Use symbols for gender (e.g., a square for male, a circle for female) and relationships (e.g., a double line for marriage, a single line for siblings, a vertical line for parent-child).
• Determine gender: Pay close attention to the rules as they often indicate the gender of the person mentioned first in the relationship (A in 'A + B').
• Work backwards or forwards: Start from the known individuals and trace the relationships towards the person whose relation you need to find.
• Break down the expression: For coded relations like in this question, decode each part of the expression sequentially.
• List known facts: Keep track of the relationships and genders you deduce at each step.

Practicing different types of blood relation puzzles, including those with symbols, is key to mastering this topic for competitive exams.
