Analyzing the Family Relationships

This question involves a logic puzzle about family connections. We need to carefully break down the statements to figure out how Sadhna is related to Durgesh.

Step 1: Understanding Geeta's Immediate Family Connections

  • We are told Geeta has a mother-in-law. This means Geeta is married. Let's call her husband 'H'.
  • Geeta's mother-in-law is the mother of H.
  • The problem states that this mother-in-law has only one son. This means H is the only son of his mother.
  • Mohan is the son of H. Therefore, Mohan is the son of Geeta and her husband H.
  • Sadhna is the sister of Mohan. Since Mohan and Sadhna share the same father (H) and mother (Geeta), Sadhna is also a child of Geeta.
  • So, Mohan and Sadhna are siblings, and Geeta is their mother.

Step 2: Clarifying Geeta's Parentage

  • The question states that Geeta is the only daughter of Vibha. This tells us that Vibha has just one child, and that child is Geeta.
  • We also learn that Ramesh is married to Vibha.
  • Since Geeta is Vibha's only child, it follows that Geeta's parents are Vibha and Ramesh.

Step 3: Determining Durgesh's Position in the Family

  • We are told that Durgesh is the only son of Ramesh.
  • We know Ramesh is married to Vibha, and their only child is Geeta (a daughter).
  • If Durgesh is Ramesh's son, but Geeta is the *only* child of Vibha (Ramesh's wife), then Durgesh cannot be the son of both Ramesh and Vibha.
  • This implies that Durgesh must be Ramesh's son from a different relationship, not with Vibha.
  • Therefore, Durgesh is Geeta's half-brother (they share the same father, Ramesh).

Step 4: Connecting Sadhna and Durgesh

  • From Step 1, we know that Geeta is the mother of Sadhna.
  • From Step 3, we know that Durgesh is the half-brother of Geeta.
  • If Durgesh is Geeta's half-brother, he is Sadhna's maternal half-uncle (he is the brother of Sadhna's mother).
  • Conversely, if Durgesh is Sadhna's uncle, then Sadhna is Durgesh's niece.

Conclusion Summary

Based on the logical breakdown:

  • Geeta is the daughter of Ramesh and Vibha.
  • Mohan and Sadhna are the children of Geeta.
  • Durgesh is the son of Ramesh, making him Geeta's half-brother.
  • Since Durgesh is the brother of Sadhna's mother (Geeta), Durgesh is Sadhna's maternal uncle.
  • Therefore, Sadhna is Durgesh's niece.
