In a certain code language,
A + B means 'A is the son of B'
A – B means 'A is the brother of B'
A x B means 'A is the wife of B'
A ÷ B means 'A is the father of B'

Based on the above, how is W related to G if 'W – O x R + K ÷ G'?

The correct answer is
Brother's wife's brother

Language Code Rules

First, establish the meaning of each coded symbol:

  • A + B means 'A is the son of B'
  • A – B means 'A is the brother of B'
  • A x B means 'A is the wife of B'
  • A ÷ B means 'A is the father of B'

Expression Breakdown: W – O x R + K ÷ G

Analyze the given expression step-by-step:

  • $W – O$: W is the brother of O.
  • $O x R$: O is the wife of R. This means R is the husband of O. Therefore, W is the brother of R's wife.
  • $R + K$: R is the son of K. This means K is R's parent.
  • $K ÷ G$: K is the father of G. This means G is K's child.

W's Relation to G Derivation

Combine the deduced relationships to find W's relation to G:

  • K is the father of G ($K ÷ G$).
  • R is the son of K ($R + K$). Thus, R is the sibling of G.
  • O is the wife of R ($O x R$).
  • W is the brother of O ($W – O$).

Since W is the brother of O, and O is the wife of R (who is G's sibling), W is the brother of the wife of G's sibling.

This relationship is described as 'Brother's wife's brother'.

Final Answer: W's Relation

W is the Brother's wife's brother of G.
