Show answer & explanation

Correct answer: B

A coded blood-relation puzzle uses symbols in place of relationship words. Following the standard convention for this puzzle type, each person belongs to one simple, single family: a person's spouse is treated as the co-parent of all of that person's children, and anyone described as a sibling is assumed to share the same two parents, unless the puzzle explicitly states otherwise (for example, a step-relation or half-sibling). The method is always the same: replace each symbol with the relation it stands for, note the gender it fixes for the person on the left, then link the relations end to end to find how the two named people are connected.

  1. 'A – B' means A is daughter of B, so A is female and one generation below B.

  2. 'B ÷ C' means B is sister of C, so B and C are siblings in the same generation.

  3. 'C # D' means D is mother of C, so D is female and one generation above C.

  4. 'D + E' means D is wife of E, so E is D's husband and, therefore, C's father.

  5. Since B is C's sibling, D and E are the parents of B as well as of C.

  6. Since A is the daughter of B, and B is a child of D and E, A belongs two generations below D and E, linked through B.

E is male (D's husband) and A is female (fixed in the first step), so A's link to E, formed two generations apart through a child (B), matches only the female grandchild relation — ruling out a relation formed by marriage (son-in-law) or a one-generation direct-child relation (son). So A is E's grand-daughter.
