Understanding Blood Relation Coding

This question involves understanding a coded system that represents blood relations. We are given specific codes for different relationships:

Our goal is to find which expression among the options represents the relationship ‘X is the mother of Y’.

To figure out ‘X is the mother of Y’, we need to think about what makes someone a mother. A mother is the wife of the father. So, X is the mother of Y means X is the wife of Y's father. Let's say Y's father is M. Then, two conditions must be met:

• X is the wife of M. Looking at the codes, 'R is the wife of S' is represented by R2S. So, 'X is the wife of M' is X2M.
• M is the father of Y. Looking at the codes, 'R is the father of S' is represented by R8S. So, 'M is the father of Y' is M8Y.

Combining these two, the expression for ‘X is the mother of Y’ should be X2M8Y.

Now let's examine each option based on these codes.

Analyzing the Options

We will break down each expression based on the given blood relation codes:

Option 1: X8M2Y

• X8M means ‘X is the father of M’.
• M2Y means ‘M is the wife of Y’.

Conclusion for Option 1: X is the father of M, and M is the wife of Y. This does not represent ‘X is the mother of Y’.

Option 2: X7M6O2Y

• X7M means ‘X is the sister of M’.
• M6O means ‘M is the brother of O’.
• O2Y means ‘O is the wife of Y’.

Conclusion for Option 2: X is the sister of M, M is the brother of O, and O is the wife of Y. This is a complex set of relations and does not represent ‘X is the mother of Y’.

Option 3: X2M8O2Y

• X2M means ‘X is the wife of M’.
• M8O means ‘M is the father of O’.
• O2Y means ‘O is the wife of Y’.

Conclusion for Option 3: X is the wife of M, M is the father of O, and O is the wife of Y. This describes X and M as parents of O, and O as wife of Y. This does not represent ‘X is the mother of Y’.

Option 4: X2M8Y

• X2M means ‘X is the wife of M’.
• M8Y means ‘M is the father of Y’.

Conclusion for Option 4: X is the wife of M, and M is the father of Y. If M is the father of Y and X is M's wife, then X must be the mother of Y. This correctly represents ‘X is the mother of Y’.

Therefore, the expression X2M8Y represents ‘X is the mother of Y’.

Additional Information on Blood Relation Questions

Blood relation questions are common in reasoning sections of competitive exams. They test your ability to understand relationships within a family structure. These questions can come in various forms:

• Direct Relations: Stating relations between individuals explicitly (e.g., "A is the brother of B").
• Puzzle Format: Giving a set of relationships and asking about the relation between two specific individuals.
• Coding Format: Like this question, where relations are represented by codes or symbols.
• Family Tree: Questions requiring you to draw or understand a family tree based on given information.

When solving coding blood relation questions, it's helpful to:

• Write down the meaning of each code clearly.
• Break down the target relationship you are looking for into simpler, coded relationships.
• Analyze each option step-by-step, translating the codes into relationships to see if it matches the target.
• Assign genders (if possible) to individuals based on the relations (e.g., wife is female, father is male, brother/sister indicates gender). Be careful not to assume gender unless specified by the relation.
