Solving Blood Relations Coding Questions

This question involves decoding relationships represented by symbols. We are given a set of codes for different blood relations. Our task is to find which given expression correctly translates to the statement 'M is the wife of O'.

Understanding the Given Blood Relation Codes

Let's first list the meaning of each symbol provided:

Target Relationship: M is the Wife of O

We need to find an expression where M is married to O, M is female, and O is male. The relationship 'M is the wife of O' implies that 'O is the husband of M'. Using our codes, this would look like 'O # M' or an equivalent relationship derived through other family members.

Analyzing Each Option to Decode Relationships

Let's decode each given expression step-by-step to determine the relationship between M and O.

Option 1: O @ R + K + P % M

• O @ R: O is the brother of R. (O is Male)
• R + K: R is the sister of K. (R is Female)
• K + P: K is the sister of P. (K is Female)
• P % M: P is the mother of M. (P is Female)

From this, we can build a family connection: P is M's mother. K is P's sister. R is K's sister. O is R's brother. This means O, R, K, and P are siblings. Since P is M's mother, O, who is P's brother, is M's maternal uncle. This expression denotes 'O is the uncle of M', not 'M is the wife of O'.

Option 2: M % P # K + R $ O

• M % P: M is the mother of P. (M is Female)
• P # K: P is the husband of K. (P is Male, K is Female)
• K + R: K is the sister of R. (K is Female)
• R $ O: R is the daughter of O. (R is Female, O is Male)

Let's trace the relationships: R is the daughter of O (O is M). K is the sister of R, so K is also the daughter of O (K is F). P is the husband of K, so P is the son-in-law of O (P is M). M is the mother of P. So, M is the mother of O's son-in-law. This expression does not denote 'M is the wife of O'.

Option 3: P $ M % R + K % O

• P $ M: P is the daughter of M. (P is Female)
• M % R: M is the mother of R. (M is Female)
• R + K: R is the sister of K. (R is Female)
• K % O: K is the mother of O. (K is Female, O is Male)

Let's trace the relationships: K is the mother of O (K is F, O is M). R is the sister of K, so R is O's aunt (R is F). M is the mother of R, so M is the mother of O's aunt. This means M is also K's mother, making M the grandmother of O (M is F). P is the daughter of M, so P is R's sister and K's sister, making P also O's aunt (P is F). This expression denotes 'M is the grandmother of O', not 'M is the wife of O'.

Option 4: M % P + K @ R $ O

• M % P: M is the mother of P. (M is Female)
• P + K: P is the sister of K. (P is Female)
• K @ R: K is the brother of R. (K is Male)
• R $ O: R is the daughter of O. (R is Female, O is Male)

Let's trace the relationships: R is the daughter of O (R is F, O is M). K is the brother of R, so K is also the son of O (K is M). P is the sister of K, so P is also the daughter of O (P is F). M is the mother of P. Since P is the daughter of O and M, and we know O is male and M is female, this implies that M and O are the parents of P. Therefore, M is the wife of O.

Conclusion

Based on our analysis, the expression M % P + K @ R $ O correctly translates to 'M is the wife of O'.

Additional Information: Strategies for Blood Relations Coding

Solving blood relations coding problems requires careful decoding and often visualizing or sketching a family tree. Here are some tips:

• Decode Symbol by Symbol: Break down the expression and decode each symbol individually, establishing the direct relationship between the two people it connects.
• Determine Gender: Some relationships (like husband, wife, mother, father, son, daughter) immediately tell you the gender of one or both individuals. Use this information. Symbols like brother/sister only give the gender of the first person.
• Build the Family Tree: As you decode, try to mentally or physically build a simple diagram or family tree showing how the people are related. This helps visualize connections.
• Work Backwards or Forwards: Depending on the expression, you might trace relationships from the beginning to the end or from the end back to the beginning to see how two specific people are connected.
• Identify the Core Relationship: Focus on the two individuals mentioned in the question (M and O in this case) and trace the path connecting them through the relationships given in the expression.
