Let's analyze the statement step-by-step: Statement:
Sohan said to Mohan, "This girl is the wife of the grandson of my mother."

Step 1: Identify the key people in the statement

• Sohan (the speaker)
• The girl (the person being referred to)
• The grandson of Sohan's mother

Step 2: Understand the relationships

• "My mother" refers to Sohan's mother.
• The "grandson of my mother" means the grandson of Sohan's mother.
• Since Sohan's mother is the grandmother, her grandson could be:
  • Sohan's son, or
  • Sohan's brother's son (Sohan's nephew).

Step 3: Check which grandson it refers to

• If the grandson is Sohan's son, then:
  • The girl is the wife of Sohan's son.
  • So, the girl is Sohan's daughter-in-law.
• If the grandson is Sohan's nephew (brother's son), then:
  • The girl is the wife of Sohan's nephew.
  • So, the girl is related as nephew's wife (no direct relation to Sohan).

Step 4: Most likely interpretation

Usually, in such puzzles, the grandson refers to Sohan's son (direct lineage).

Final answer:

Sohan is the father-in-law of the girl.
Or simply, the girl is Sohan's daughter-in-law.
