P is the father of Q and R. How are Q and R related?

Explanation:

• Given: P is the father of Q and R
• This means:
  • Q and R have the same father (P)

👉 When two people share the same parents, they are called siblings (brother/sister)

❌ Why other options are wrong:

• Father ❌ → Q and R are not fathers
• Grandmother ❌ → No such relation given
• Mother ❌ → Not mentioned

   • Brother or Sister
   • Same parents (or at least one common parent)
2. Types of siblings:
   • Full siblings → same mother & father
   • Half siblings → one parent same
