In a certain code language, A + B means ‘A is the daughter 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 E related to K if ‘E – F + G x H ÷ K’?
Husband
Brother
Son
Father
Brother
Work backwards from the expression E - F + G x H / K using a family tree structure: E-F (sibling), F+G (F daughter of G), G x H (G wife of H), H/K (H father of K).
Work backwards from the expression E - F + G x H / K using a family tree structure: E-F (sibling), F+G (F daughter of G), G x H (G wife of H), H/K (H father of K).
Analyze E - F
E - F means E is the brother of F. This establishes E is male and is at the same generational level as F.
Analyze F + G
F + G means F is the daughter of G. Since E is the brother of F, E and F are children of G.
Analyze G x H
G x H means G is the wife of H. Therefore, H is the father of both E and F.
Analyze H / K
H / K means H is the father of K. Since H is the father of E, F, and K, E and K are siblings.
A: Husband is incorrect as E is the sibling of K; C: Son is incorrect as E is the same generation as K; D: Father is incorrect as H is the father of both.
B is correct because the logical sequence confirms E is the brother of F, and they share parents H and G, making E a brother to sibling K.
