Ajay is Kavita's brother. Kavita is married to Suresh, and they have two children, Rahul and Priya. Suresh has a sister named Deepa, who is married to Anand and they have a daughter named Reena. Describe how Ajay is related to Deepa and Reena, and discuss Anand's relationship to Kavita and Rahul.
Respond very briefly.
Ajay is Kavita's brother. Kavita's husband, Suresh, is Deepa's brother. This means Ajay is Suresh's brother-in-law. Since Deepa is Suresh's sister, Ajay is Deepa's brother-in-law as well.

Reena is the daughter of Deepa and Anand. Deepa is Suresh's sister and Kavita is Suresh's wife, which makes Reena, Suresh's niece. As Ajay is Suresh's brother, Reena is also Ajay's niece.

Anand, being married to Deepa, is Suresh's brother-in-law. As Kavita is Suresh's wife, Anand is also Kavita's brother-in-law. Furthermore, since Rahul is Kavita and Suresh's son, Anand is Rahul's uncle through marriage.
