Decoding E to K: Relationship Explanation

We are given a coded language relating individuals and need to find the relationship between E and K based on the expression 'E - F + G $\div$ H x K'.

Let's break down the expression step-by-step using the provided codes:

  • E - F means 'E is the brother of F'.
  • F + G means 'F is the daughter of G'. Since E is F's brother, E is also the son of G.
  • G $\div$ H means 'G is the father of H'. This confirms G is male and H is G's child.
  • H x K means 'H is the wife of K'. This means K is the husband of H.

Step-by-Step Relationship Analysis

Combining these facts:

  1. From E - F and F + G, we establish that E is the son of G.
  2. From G $\div$ H, we know G is the father of H.
  3. Since E and H share the same father (G), E and H are siblings. As E is male (brother of F), E is the brother of H.
  4. From H x K, we know H is the wife of K.
  5. Therefore, E is the brother of H, and H is the wife of K. This makes E the brother of K's wife.

The relationship of E to K is 'Brother's wife's brother'.
