Pointing towards a lady in a photograph, a girl says, "Vidit's grandmother is the mother-in-law of this lady." How is the lady in the photograph related to Vidit?

Introduction / Context:

This blood-relation question involves indirect information given through a photograph and the term "mother-in-law". The aim is to connect Vidit, his grandmother and the lady in the photograph. Such questions are typical in verbal reasoning tests because they check whether you can track indirect relationships like in-laws and grandparents without mixing up the generations.

Given Data / Assumptions:

• A girl is pointing to a lady in a photograph.
• She says: "Vidit's grandmother is the mother-in-law of this lady."
• Vidit has a grandmother, who is the mother of one of Vidit's parents.
• A mother-in-law is defined as the mother of one's husband or wife.
• We assume the standard exam convention that the grandmother mentioned is the parent of Vidit's father or mother, and that she is mother-in-law only through Vidit's parent's marriage.
• We need to find how the lady in the photograph is related to Vidit.

Concept / Approach:

The phrase "Vidit's grandmother is the mother-in-law of this lady" means that this lady's spouse is a child of Vidit's grandmother. That child is very likely one of Vidit's parents. If we interpret this in the simplest, most standard way, the lady is married to Vidit's father or mother and is therefore Vidit's other parent. In most such reasoning questions, the intended interpretation is that she is Vidit's mother.

Step-by-Step Solution:

Verification / Alternative check:

Check alternative possibilities: G might have more than one child, and the lady could be married to another child of G, making her an aunt by marriage. However, typical exam questions assume a minimal family structure where the grandmother's role as mother-in-law arises through the marriage that created Vidit's branch of the family tree. The most direct and test-friendly reading is that the lady is married to Vidit's parent, making her his mother.

Why Other Options Are Wrong:

She is not Vidit's sister, because a sister would be a child of Vidit's parents, not their spouse.

She is not Vidit's grandmother, as the grandmother is explicitly a different person whose relationship to the lady is described as mother-in-law.

"Aunt" would require the lady to be married to Vidit's uncle or to be a sibling of Vidit's parent, which is not the direct reading of the given statement.

Common Pitfalls:

Many students confuse mother-in-law relationships and start imagining that the grandmother might herself be the lady in the photograph. Remember: the grandmother is the mother-in-law, not the person being pointed at. Also, do not overcomplicate the family unless the question forces you to; standard reasoning questions usually intend the simplest structure in which the described relation holds.

Final Answer:

The lady in the photograph is Vidit's mother.
