If the data either in statement I alone or in statement II alone is sufficient to answer the question.
Step-by-step solution
Following description is about a family.
What is the difference between the total number of males and females in the family?
Statement I:& Veena has six daughters, who have a brother. Veena is the wife of Shyam.
Statement II:& Shyam is the father of six daughters. Ram’s mother Veena is married to Shyam. Ram is a male.
Checking statement I:
Veena is the wife of Shyam, this means that Veena is a female and Shyam is a male. Veen has six daughters, who have a brother means that Veena has a son. Thus total number of males are 2 and females are 7.
Clearly, the required difference is 5.
Hence data in statement I is sufficient to answer the question.
Checking statement II:
Ram and Shyam are the male members.
Veena and her six daughters are the female members.
So, the required difference is 5.
Hence data in statement II is also sufficient to answer the question.
Therefore data in either statement I alone or II alone is sufficient to answer the question.
Hence option C is correct.

Statement II:& Shyam is the father of six daughters. Ram’s mother Veena is married to Shyam. Ram is a male.
Checking statement I:
Veena is the wife of Shyam, this means that Veena is a female and Shyam is a male. Veen has six daughters, who have a brother means that Veena has a son. Thus total number of males are 2 and females are 7.
Clearly, the required difference is 5.
Hence data in statement I is sufficient to answer the question.
Checking statement II:
Ram and Shyam are the male members.
Veena and her six daughters are the female members.
So, the required difference is 5.
Hence data in statement II is also sufficient to answer the question.
Therefore data in either statement I alone or II alone is sufficient to answer the question.
Hence option C is correct.
