Raj is married to Meena, and they have two children, Rahul and Priya. Meena's brother, Arun, is married to Divya, and they have a son named Vikram. Explain how Divya is related to Rahul and how Vikram is related to Priya. Finally, describe what relationship Raj has to Arun. Respond very briefly.
Divya is married to Arun, who is Meena's brother. Meena is Rahul's mother. Therefore, Divya is Rahul's aunt by marriage. Rahul would refer to Divya as his aunt since she is his mother's brother's wife.

Vikram is Arun and Divya's son. Arun is Meena's brother, and Meena is Priya's mother, making Arun her uncle. This means Vikram is Priya's cousin because their parents are siblings.

Raj is married to Meena, and Arun is Meena's brother. Thus, Raj is Arun's brother-in-law, as he is the husband of Arun's sister.
