Solving Blood Relations Puzzle
This question asks us to determine the relationship between two individuals, L and M, based on a given coded expression representing familial ties. We need to decode the expression segment by segment using the provided rules.
Understanding the Relationship Codes
Here are the defined relationship codes:
- 'A + B' means 'A is the son of B' ($\text{A} \rightarrow \text{Son}, \text{B} \rightarrow \text{Parent}$)
- 'A - B' means 'A is the husband of B' ($\text{A} \rightarrow \text{Husband}, \text{B} \rightarrow \text{Wife}$)
- 'A $\times$ B' means 'A is the wife of B' ($\text{A} \rightarrow \text{Wife}, \text{B} \rightarrow \text{Husband}$)
- 'A $\div$ B' means 'A is the brother of B' ($\text{A} \rightarrow \text{Brother}, \text{B} \rightarrow \text{Sibling}$)
Decoding the Expression: K $\div$ Q $\times$ M + R $\times$ D + H - L
Let's break down the expression from left to right:
- K $\div$ Q: According to the $\div$ rule, K is the brother of Q. K and Q are siblings.
- Q $\times$ M: According to the $\times$ rule, Q is the wife of M. This means M is the husband of Q. Q and M are a married couple.
- M + R: According to the + rule, M is the son of R. R is the parent of M.
- R $\times$ D: According to the $\times$ rule, R is the wife of D. This means D is the husband of R. R and D are a married couple. Since M is the son of R, and R is the wife of D, M is also the son of D. R and D are the parents of M.
- D + H: According to the + rule, D is the son of H. H is the parent of D.
- H - L: According to the - rule, H is the husband of L. This means L is the wife of H. H and L are a married couple. Since D is the son of H, and H is the husband of L, D is also the son of L. H and L are the parents of D.
Tracing the Relationship between L and M
Let's connect the relationships we've found to link L and M:
- H and L are parents of D. (From H - L and D + H)
- D and R are parents of M. (From M + R and R $\times$ D)
So, L is the parent of D, and D is the father of M (since D is husband of R). This makes L the grandmother of M.
To determine if L is the maternal or paternal grandmother, we look at which parent of M (D or R) is related to L. L is a parent of D. D is the father of M. Therefore, L is related to M through M's father, D. This means L is the paternal grandmother of M.
Summary of Relationships
| Relation | Interpretation | Gender |
|---|---|---|
| K $\div$ Q | K is brother of Q | K: Male, Q: Female or Male |
| Q $\times$ M | Q is wife of M | Q: Female, M: Male |
| M + R | M is son of R | M: Male, R: Female or Male |
| R $\times$ D | R is wife of D | R: Female, D: Male |
| D + H | D is son of H | D: Male, H: Female or Male |
| H - L | H is husband of L | H: Male, L: Female |
From the table and decoding:
- H and L are a couple (H is husband, L is wife).
- D is the son of H (and L). So, D is their child.
- D and R are a couple (D is husband, R is wife).
- M is the son of R (and D). So, M is their child.
This chain shows: L $\rightarrow$ D (L is parent of D) $\rightarrow$ M (D is parent of M). Since L is female and parent of D, and D is father of M, L is M's paternal grandmother.
Conclusion: Relationship between L and M
Based on the step-by-step decoding of the expression K $\div$ Q $\times$ M + R $\times$ D + H - L, we determined that L is the wife of H, H and L are the parents of D, and D is the father of M. Therefore, L is the paternal grandmother of M.

Additional Information: Solving Coded Blood Relations Problems
Coded blood relations questions require careful decoding of each symbol or phrase. A useful strategy is to draw a family tree or diagram as you decode the expression. Represent individuals and generations clearly. Use symbols for relationships (like a double arrow for marriage, a single arrow for parent-child, and a horizontal line for siblings). Indicate gender where specified. This visual aid helps in tracing the final relationship requested in the question.
