Blood Relation Symbol Meanings

First, understand the meaning of each symbol:

  • 'P @ Q' means 'Q is the mother of P'.
  • 'P $ Q' means 'Q is the husband of P'. (This implies P is the wife)
  • 'P # Q' means 'Q is the sister of P'.
  • 'P & Q' means 'Q is the son of P'. (This implies P is the parent)

Expression Breakdown: Z # M $ C & D & E

Now, let's break down the given expression step-by-step:

  1. Z # M: Based on the definition, 'M is the sister of Z'. This tells us M is female.
  2. M $ C: Based on the definition, 'C is the husband of M'. This means M and C are married, and C is male. M is female.
  3. C & D: Based on the definition, 'D is the son of C'. This tells us D is male, and C is a parent (father) of D.
  4. D & E: Based on the definition, 'E is the son of D'. This tells us E is male, and D is a parent of E.

Deriving E's Relationship to M

Let's combine the deduced relationships to form the family structure:

  • M is married to C.
  • C is the father of D.
  • Since C is D's father and married to M, M is D's mother.
  • D is the parent of E.
  • Since D is E's parent and E is male, E is the son of D.

Therefore, the lineage is:

  • M and C are the parents of D.
  • D is the parent of E.

This makes M the grandmother of D's child, E. E is the son of D, making him the grandson of M.

Final Relation: E to M

The question asks how E is related to M. Based on the analysis, E is the grandson of M.
