Abdul, Rahila, Karan, Rahul, Reena, Manju and Heena are members of a family consisting of four adults and three children. Two of them, Manju and Heena are girls. Abdul and Rahul are brothers and Abdul is a doctor. Reena is an Engineer married to one of the brothers and has two children. Rahila is married to Rahul and Heena is their child. Who is Karan?

Abdul's Son

The correct answer is Option (1) → Abdul's Son

Given Information:

• There are 7 members: Abdul, Rahila, Karan, Rahul, Reena, Manju, Heena.
• 4 adults, 3 children. Girls: Manju, Heena.
• Abdul and Rahul are brothers; Abdul is a doctor.
• Reena is an engineer, married to one of the brothers, and has two children.
• Rahila is married to Rahul, and Heena is their child.

Deductions:

• Rahul is married to Rahila → Heena is their daughter → Heena is Rahul & Rahila's child.
• Reena is married to the other brother (Abdul) and has two children.
• Manju must be one child of Abdul and Reena (girl).
• Only one person left unassigned: Karan.
• Since Abdul and Reena have two children (Manju and Karan), and Karan is the only male child left,

Therefore, Karan is Abdul's son.
