Question

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’ and A ÷ B means ‘A is the father of B’. Based on the above, how is S related to K if ‘S + D ÷ F x H – K’?

1. A. Brother's wife's father
2. B. Wife's brother
3. C. Wife's father
4. D. Brother's wife's brother (Correct answer)

Correct Answer

Option D — Brother's wife's brother

Detailed Solution & Explanation

The correct answer is Brother's wife's brother.

Key Points

• Decode S + D ÷ F × H − K one symbol at a time:
  • S + D → S is the son of D
  • D ÷ F → D is the father of F
  • F × H → F is the wife of H
  • H − K → H is the brother of K
• Since D is the father of both S and F, S and F are siblings; F being a wife is female, so F is S's sister.
• The question asks how S is related to K, so trace outward from K:
  • K's brother is H → H's wife is F → F's brother is S.
• So S is K's brother's wife's brother.

Additional Information

• Direction matters. Read from the person named second in the question. Tracing from S instead gives "sister's husband's brother" — the same relationship described from the opposite end, and not among the options.
• Gender is often established indirectly rather than stated. Here F must be female because F is a wife, and that inference is what makes S and F brother and sister rather than two brothers.
• Draw a quick family tree with generations on separate rows and marriages as horizontal links; symbolic relation questions become unreadable if held in the head.
• Work the symbols strictly left to right as given, building the tree incrementally rather than trying to interpret the whole expression at once.
