Answer» Correct Answer - Option 1 : (1, 3, 5) Given: A = (1, 2, 3, 4) B = (2, 4, 5) Concept used: If two sets X and Y, X - Y = Set of all the elements present in X but not in Y Y - X = Set of all the elements present in Y but not in X X ∪ Y = Set of all the elements present in either X or Y Calculation: A - B = (1, 2, 3, 4) - (2, 4, 5) ⇒ (1, 3) B - A = (2, 4, 5) - (1, 2, 3, 4) ⇒ (5) (A - B) ∪ (B - A) = (1, 3) ∪ (5) ⇒ (1, 3, 5) ∴ The value of (A - B) ∪ (B - A) is (1, 3, 5). |
