Solving Blood Relation Puzzles with Code Decoding
This question asks us to determine the relationship between two individuals, L and Y, based on a coded expression representing blood relationships. We are given a set of codes and their meanings, and we need to decode the given expression step-by-step to build the family links and find the required relationship.
Understanding the Blood Relation Codes
First, let's understand what each symbol in the code represents:
A + Bmeans ‘A is the father of B’.A – Bmeans ‘A is the sister of B’.A × Bmeans ‘A is the brother of B’.A ÷ Bmeans ‘A is the mother of B’.
Decoding the Expression U + H × L – Q ÷ R – Y
Let's break down the given expression segment by segment from left to right:
- U + H: According to the code,
+means 'father'. So, U is the father of H. - H × L: According to the code,
×means 'brother'. So, H is the brother of L. Since U is the father of H, and H is the brother of L, U is also the father of L. H and L are siblings. - L – Q: According to the code,
–means 'sister'. So, L is the sister of Q. Since U is the father of L, and L is the sister of Q, U is also the father of Q. L, H, and Q are all siblings. - Q ÷ R: According to the code,
÷means 'mother'. So, Q is the mother of R. Since Q is a sibling of L and H, and U is their father, U is the maternal grandfather of R. - R – Y: According to the code,
–means 'sister'. So, R is the sister of Y. Since Q is the mother of R, and R is the sister of Y, Q is also the mother of Y. R and Y are siblings.
Determining the Relationship between L and Y
From our decoding, we know the following relationships:
- L is the sister of Q.
- Q is the mother of Y.
If Q is Y's mother, and L is Q's sister, then L is Y's mother's sister. A mother's sister is also known as a maternal aunt.
Analyzing the Options
Let's look at the given options:
- Sister: L and Y are not siblings. L is from the previous generation relative to Y.
- Mother’s sister: This matches our derived relationship. L is the sister of Q, and Q is the mother of Y.
- Mother’s brother: L is female (L is the sister of Q). A mother's brother is a maternal uncle.
- Maternal grandmother: A maternal grandmother is the mother of one's mother. L is Q's sister, not Q's mother.
Based on our analysis, the relationship between L and Y is that L is Y's mother's sister.
| Expression Segment | Meaning | Inferred Relationship |
|---|---|---|
| U + H | U is father of H | U → Father; H → Child |
| H × L | H is brother of L | H, L → Siblings; U → Father of L |
| L – Q | L is sister of Q | L, H, Q → Siblings; U → Father of Q |
| Q ÷ R | Q is mother of R | Q → Mother; R → Child; U → Maternal Grandfather of R |
| R – Y | R is sister of Y | R, Y → Siblings; Q → Mother of Y; U → Maternal Grandfather of Y |
From the inferred relationships, L is the sister of Q, and Q is the mother of Y. Therefore, L is the mother's sister of Y.

Additional Information: Tips for Solving Blood Relation Questions
Blood relation questions involving codes or complex expressions can be solved systematically:
- Identify the meaning of each symbol or code.
- Break the given expression into smaller parts.
- For each part, determine the relationship between the two individuals.
- Link these individual relationships together to form a family tree or diagram. You can use symbols like
<-->for siblings,↓for parent-child, etc., and note gender. - Trace the path between the two individuals whose relationship is asked.
- Be careful with gender; sometimes, the code only specifies the relation of the first person to the second, not the second person's gender. However, 'sister' and 'brother' imply gender.
Practice decoding different types of expressions to become proficient in solving blood relation problems quickly and accurately.
