A % B means ‘A is the daughter of B’ A = B means ‘A is the sister of B’ A $ B means ‘A is the father of B’ X % Y = Z % W $ V, then how is Z related to V?
Sister
Solving Blood Relation Puzzles
This question involves understanding relationships based on coded symbols. Let's break down the meaning of each symbol provided:
- A % B means ‘A is the daughter of B’
- A = B means ‘A is the sister of B’
- A $ B means ‘A is the father of B’
We are given the expression: X % Y = Z % W $ V. We need to find out how Z is related to V.
Let's analyze the expression step by step:
- X % Y: According to the definition, X is the daughter of Y. This tells us the gender of X (female) and that Y is X's parent.
- Y = Z: According to the definition, Y is the sister of Z. This tells us the gender of Y (female) and that Y and Z are siblings. Since Y is the sister of Z, Z could be a brother or a sister.
- Z % W: According to the definition, Z is the daughter of W. This tells us the gender of Z (female) and that W is Z's parent.
- W $ V: According to the definition, W is the father of V. This tells us the gender of W (male) and that W is V's parent.
Now let's combine the relevant parts to find the relationship between Z and V.
From step 3, we know that Z is the daughter of W.
From step 4, we know that W is the father of V.
If W is the father of V, then W is V's parent. Since W is also the parent of Z (Z is W's daughter), W is a common parent for both Z and V.
When two individuals share a common parent, they are siblings. We know that Z is female because Z is the daughter of W.
Therefore, Z is the sister of V.
Let's summarize the key relationships we used:
- Z is the daughter of W (Z is female).
- W is the father of V (W is male).
Since Z is the daughter of W and W is the father of V, Z and V share W as a parent. This makes them siblings. As Z is female, Z is the sister of V.

Additional Information: Understanding Blood Relations
Blood relation questions test your ability to decipher family connections from a series of given relationships. These problems often involve building a mental or visual family tree to track individuals and their links.
- Key Terms: Daughter, Son, Sister, Brother, Mother, Father, Aunt, Uncle, Grandparent, Grandchild, Sibling, Cousin, Niece, Nephew.
- Building a Family Tree: Start with a known relationship and build outwards. Represent individuals and draw lines connecting them with labels indicating the relationship (e.g., parent-child, siblings, spouse). Use symbols (like circles for females, squares for males) if helpful.
- Tracking Gender: Pay close attention to phrases that indicate gender (e.g., 'daughter', 'sister' indicates female; 'father', 'brother' indicates male). If a relationship doesn't specify gender (e.g., 'child', 'sibling'), the gender of that person might be unknown unless stated elsewhere.
- Working Backwards or Forwards: You can start from one end of the given expression and deduce relationships sequentially, or identify the two individuals whose relationship is asked and trace the path between them through common relatives.
In the given problem, by breaking down the expression X % Y = Z % W $ V, we isolated the relationships involving Z and V (Z % W and W $ V), which clearly showed W is the parent of both, and Z is female, leading to the conclusion that Z is V's sister.
