Class 12 Maths · Relations And Functions · Conceptual Answer #159

An equivalence relation partitions A into three distinct classes A₁,A₂,A₃. Find their union and their common intersection.

✅ Step-by-Step Solution

Final Answer: A₁∪A₂∪A₃=A; A₁∩A₂∩A₃=∅.
  1. Equivalence classes cover A and distinct classes are disjoint.
  2. A₁∪A₂∪A₃=A; A₁∩A₂∩A₃=∅.

📋 CBSE Stepwise Marking Scheme

  • [0.5 marks] Equivalence classes cover A and distinct classes are disjoint.
  • [0.5 marks] A₁∪A₂∪A₃=A; A₁∩A₂∩A₃=∅.
