Puzzle Solution

Quick Solution

This puzzle requires building a family tree from the given clues to determine the relationships between the members.

1. Deduce the Family Structure

  • The clue "The grandfather is the family is the heaviest" combined with other weight-related clues establishes that A is the grandfather.
  • The clue "E who married a person heavier than C" means E must be married to A. Since A is the grandfather, E is the grandmother. This forms the first married couple.
  • The remaining people are B, C, D, and F. We are told B is male, C is a lady (female), and D is a brother (male).
  • Since "D is the brother of F," they are siblings and cannot be a married couple.
  • This leaves B and C as the only possible second married couple.
  • For the family to have three generations, D and F must be the children of B and C.

2. Answer the Question

The question asks for the relationship of E to D.

  • From our family tree, E is the grandmother.
  • D is the child of B and C, making him the grandson of A and E.

Therefore, E is D's Grandmother.

Final Answer: E is related to D as his Grandmother.
