If ‘A – B’ means A is mother of B, ‘A $ B’, A is daughter of B, ‘A @ B’ means A is father of B and ‘A = B’ means A is son of B.

If M – N @ O $ P, then how O is related to M?

The correct answer is

Granddaughter

Solving Blood Relation Code Puzzles

This question involves decoding relationships based on a set of defined codes for blood relations. We are given an expression involving these codes and asked to find the relationship between two individuals.

Decoding the Blood Relation Codes

Let's first understand what each symbol represents:

  • A – B: A is mother of B
  • A $ B: A is daughter of B
  • A @ B: A is father of B
  • A = B: A is son of B

Analyzing the Given Expression: M – N @ O $ P

We will break down the expression segment by segment from left to right to build the family tree:

  1. M – N: According to the first code, M is the mother of N. This tells us M is female and is one generation above N.
  2. N @ O: According to the third code, N is the father of O. This tells us N is male and is one generation above O.
  3. O $ P: According to the second code, O is the daughter of P. This tells us O is female and P is one generation above O.

Constructing the Family Relationship

From the analysis above, we can establish the following connections:

  • M is the mother of N.
  • N is the father of O.
  • O is the daughter of P.

Since N is the father of O and O is the daughter of P, it implies that N and P are the parents of O. If N is the father, then P must be the mother of O. This also means N and P are married or partners.

Now, let's connect M to O:

  • M is the mother of N.
  • N is the father of O.

This structure indicates that N is the child of M, and O is the child of N. Therefore, M is in the generation above N, and N is in the generation above O. This places M two generations above O. M is the mother of N, who is O's father. This makes M the paternal grandmother of O.

The relationship O $ P tells us O is a daughter, confirming O's gender as female.

Determining the Relationship of O to M

We found that M is the paternal grandmother of O. The question asks how O is related to M. If M is the grandmother of O, then O is the grandchild of M. Since we know O is female (O is the daughter of P), O is specifically the granddaughter of M.

Evaluating the Options

Let's look at the given options based on our deduced relationship:

  • Granddaughter: This matches our conclusion that O is the granddaughter of M.
  • Husband: Incorrect, O is female and multiple generations below M.
  • Wife: Incorrect, O is female and multiple generations below M.
  • Grand Father: Incorrect, this describes M's relationship to O if M were male and two generations above, but M is female and O is the grandchild.

Based on the decoding and relationship analysis, the correct relationship is that O is the granddaughter of M.

Expression Part Relationship Deduction
M – N A is mother of B M is mother of N (M is female)
N @ O A is father of B N is father of O (N is male)
O $ P A is daughter of B O is daughter of P (O is female)

Summary of Relationships

  • M is the mother of N.
  • N is the father of O.
  • O is the daughter of P.
  • Combining N@O and O$P, N is father of O and O is daughter of P, so P is mother of O.
  • N and P are parents of O.
  • M is the mother of N (O's father).
  • Therefore, M is O's paternal grandmother.
  • If M is O's grandmother, O is M's grandchild.
  • Since O is female (daughter), O is M's granddaughter.

Blood Relation Puzzle Answer

The relationship between O and M is that O is the granddaughter of M.

Additional Information: Solving Blood Relation Questions

Blood relation questions test your ability to understand and deduce relationships between family members. When solving code-based blood relation problems, it's helpful to:

  • Carefully note down what each code or symbol represents.
  • Break down the given expression into smaller segments.
  • Analyze each segment to determine the direct relationship between the two individuals mentioned.
  • Combine the relationships sequentially to build a family tree or diagram. This helps visualize the connections.
  • Determine the gender of individuals whenever possible based on the codes (e.g., 'mother' implies female, 'father' implies male, 'son' implies male, 'daughter' implies female).
  • Pay attention to the question asking for the relationship of X to Y, versus Y to X, as the relationship might be different depending on the direction.
  • Practice decoding various combinations of symbols and individuals to improve speed and accuracy.

Building a simple diagram, even mentally, can prevent errors when dealing with multiple generations or complex relationships.
