Solving Blood Relation Puzzles with Symbols

This problem involves understanding relationships represented by specific symbols and then deducing the relationship between two individuals based on a given expression. Let's first understand what each symbol represents:

  • A = B means ‘A is the father of B’
  • A # B means ‘A is the mother of B’
  • A @ B means ‘A is the son of B’

The given expression is Q = K # D @ H = R. We need to break this expression down into individual relationships:

  1. Q = K: Using the rule A = B meaning ‘A is the father of B’, we interpret Q = K as ‘Q is the father of K’.
  2. K # D: Using the rule A # B meaning ‘A is the mother of B’, we interpret K # D as ‘K is the mother of D’.
  3. D @ H: Using the rule A @ B meaning ‘A is the son of B’, we interpret D @ H as ‘D is the son of H’.
  4. H = R: Using the rule A = B meaning ‘A is the father of B’, we interpret H = R as ‘H is the father of R’.

Now let's combine these relationships to determine how Q is related to H.

  • From 1, we know Q is the father of K.
  • From 2, we know K is the mother of D.
  • From 3, we know D is the son of H.

If K is the mother of D and D is the son of H, it means that K and H are the parents of D. Since K is the mother, H must be the father of D. This also implies that K and H are a couple (husband and wife), with H being K's husband.

We established that Q is the father of K. Since K is H's wife, Q is the father of H's wife. The father of one's wife is known as the father-in-law.

Therefore, Q is the father-in-law of H.

Let's summarize the key relationships deduced:

Relationship Interpretation
Q = K Q is the father of K
K # D K is the mother of D
D @ H D is the son of H
Combining K#D and D@H K and H are parents of D. K is mother, so H is father of D. K is H's wife.
Combining Q=K and K is H's wife Q is father of K, K is H's wife. So Q is father of H's wife.

The relation between Q and H is that Q is H's father-in-law.

Additional Information on Blood Relation Reasoning

Blood relation reasoning questions test your ability to understand and decipher complex family relationships. These questions often use symbols, codes, or direct statements to describe relationships between members of a family. To solve these problems effectively, it is helpful to:

  • Read the instructions carefully to understand what each symbol or code represents.
  • Break down the given expression or statement into smaller, manageable parts.
  • Draw a family tree or diagram to visually represent the relationships. This helps in seeing the connections between different individuals.
  • Determine the gender of each person if possible, as relations like son, daughter, father, mother, brother, sister depend on gender. Symbols might or might not explicitly state gender, but relationships like 'father of' or 'mother of' imply the gender of the first person.
  • Trace the relationship step-by-step from the first person mentioned to the last person you need to find the relation with.
  • Be mindful of common pitfalls, such as confusing maternal and paternal relationships or misinterpreting symbols.

Practice with various types of blood relation questions using symbols, coded language, or direct statements to improve your speed and accuracy in solving these reasoning problems.
