If ‘A + B’ means ‘A is the mother of B’, ‘A - B’ means ‘A is the father of B’, ‘A × B’ means ‘A is the brother of B’, ‘A & B’ means ‘A is the son of B’, then how is M related to K in the expression ‘N − M + T × L & G & K’?
Solving the Blood Relation Puzzle: N − M + T × L & G & K
This question asks us to determine the relationship between two individuals, M and K, based on a given expression and a set of defined relationships represented by symbols. Let's break down the expression step by step using the provided definitions:
- ‘A + B’ means ‘A is the mother of B’
- ‘A - B’ means ‘A is the father of B’
- ‘A × B’ means ‘A is the brother of B’
- ‘A & B’ means ‘A is the son of B’
The expression given is: N − M + T × L & G & K
Breaking Down the Expression
Let's analyze the expression piece by piece from left to right to build the family tree:
- N − M: According to the definition ‘A - B’ means ‘A is the father of B’, this part means N is the father of M. So, N is male.
- M + T: According to the definition ‘A + B’ means ‘A is the mother of B’, this part means M is the mother of T. Since N is M's father, this relation implies that N is M's father, and M is T's mother. N is not directly related to T based on these two steps alone in the chain N-M+T. However, M is a child of N and M is a parent of T.
- T × L: According to the definition ‘A × B’ means ‘A is the brother of B’, this part means T is the brother of L. Since M is the mother of T, and T is the brother of L, M is also the mother of L. T is male. The gender of L is not yet determined by this step alone.
- L & G: According to the definition ‘A & B’ means ‘A is the son of B’, this part means L is the son of G. We already know that M is the mother of L. If L is the son of G, and M is the mother of L, it means that G must be the father of L. Thus, M and G are the parents of L (and T). G is male.
- G & K: According to the definition ‘A & B’ means ‘A is the son of B’, this part means G is the son of K. G is male, which we already established.
Establishing the Relationships
From the analysis, we have the following relationships:
- N is the father of M.
- M is the mother of T and L.
- T is the brother of L (T is male).
- L is the son of G (L is male).
- G is the father of L (and T), and G is the husband of M.
- G is the son of K.
We are asked to find how M is related to K.
We know that G is the son of K, and M is the wife of G.
Therefore, M is the wife of K's son.
Final Relationship
Based on the step-by-step analysis, M is related to K as K's son's wife.
This matches the relationship: Son’s wife.
