Study the following information and answer the question given below.
In a family of six members, Ram is the father of Rinku. Radha is the mother of Ramesh. Ramesh is the uncle of Rita. Ritika is the daughter-in-law of Ram, and Ritika has a daughter.
Who is the grandmother of Rita?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Radha
The six members are Ram, Rinku, Radha, Ramesh, Rita and Ritika. A daughter-in-law is the wife of one’s son, so Ritika is married to a son of Ram.
Ritika’s husband is a son of Ram in the family: Rinku or Ramesh. If he were Ramesh, his daughter would have to be one of the six, but Rita is his niece, Radha is his mother and Rinku is Ram’s child; so Ritika’s husband is Rinku
Ritika’s daughter is then not Rinku (her husband) and not Radha (Radha’s son Ramesh would be Ritika’s grandson, too young to be the uncle of anyone in the family), so she is Rita
So Rita’s parents are Rinku and Ritika, and Ramesh, her uncle, is a brother of one of them
Radha is the mother of Ramesh, so she is the mother of one of Rita’s parents
So Radha is the grandmother of Rita
The figure shows Ramesh as Rinku’s brother; if he is Ritika’s brother instead, Radha is Rita’s maternal grandmother, and the answer is the same.
Why the other options are incorrect
Option (1) Ram — Incorrect. Ram is a male, the father of Rinku and so Rita’s grandfather.
Option (2) Rinku — Incorrect. Rinku is Ritika’s husband and Rita’s father.
Option (3) Ramesh — Incorrect. Ramesh is Rita’s uncle, as given.
