Given relationships:
- Amit and Pankaj are brothers
- Rekha is the daughter of Kapil
- Rekha is the sister of Amit
Since Rekha is the daughter of Kapil, this means:
Kapil is Rekha's father
Since Rekha is the sister of Amit, this means:
Amit and Rekha are siblings with the same parents
Therefore, Kapil is also Amit's father
Since Amit and Pankaj are brothers, they share the same parents.
Since Kapil is Amit's father, Kapil is also Pankaj's father
