(3) Raghu is the brother of meghna

Answer 2

Of the given statements, the one that cannot be said to be definitely true is that Raghu is the brother of Meghna (Statement 3)

• From the given clues, we can decipher that Varun has two siblings, Meghna and Nikhil
• Since it is given that Prerna is Nikhil's brother, she is also Varun and Meghna's mother
• It is also given that Raghu is Varun's father, which indicates that he is also the paternal figure of Meghna and Nikhil

With this information available to us, we can eliminate and check the given statements;

• It is true that Varun is the son of Prerna
• We can also infer that Raghu and Prerna are husband and wife since they share three children
• Prerna is Varun's mother based on the observations made above

The only statement that does not make any sense is that Raghu is the brother of Meghna since it is already established that he is her father
