Logical & analytical reasoning Medium

A joint family consists of seven members A, B, C, D, E, F and G with three females. G is a widow and sister-in-law of D’s father F. B and D are siblings and A is daughter of B. C is cousin of B. Who is E?

  1. 1.Wife of F
  2. 2.Grandmother of A
  3. 3.Aunt of C

Select the correct answer using the code given below:

Answer & explanation

Answer: (d) 1, 2 and 3

F is the father of B and D. G is F's widowed sister-in-law, so her late husband was F's brother, and C, B's cousin, is her child. The one slot left in the family — the mother of B and D — belongs to E, who is therefore F's wife, A's grandmother and C's aunt.

  1. F is D's father; B and D are siblings, so F is B's father too, and A (B's daughter) is F's granddaughter.
  2. G is a widow and F's sister-in-law, so her husband — F's brother — is no more.
  3. C is B's cousin, so C is the child of G and F's late brother.
  4. E completes the family as F's wife, the mother of B and D; the three females are then G, A and E.
  5. So E is F's wife, A's grandmother and, as the wife of C's uncle, C's aunt.
  • ✓ 1. E is the mother of B and D, hence F's wife.
  • ✓ 2. A is the daughter of E's son or daughter B, so E is A's grandmother.
  • ✓ 3. C is the child of F's brother; F's wife E is C's aunt.

Remember · Place each stated relation on a family tree; the leftover member usually fills the one slot the tree still needs.
