Question

 If A = { x; x² – 5x + 6 = 0} 

B = {2, 4}, C = {4, 5} then A × (B ∩ C) is - 

 (A) {(2, 4), (3, 4)} 

 (B) {(4, 2), (4, 3)} 

 (C) {(2, 4),(3, 4), (4, 4)} 

 (D) {(2, 2),(3, 3),(4, 4), (5, 5)} 

Answer 1

Correct option (A) {(2, 4), (3, 4)}

Explanation: 

A = {3, 2}; B = {2, 4}; C = {4, 5} 

⇒ A ×(B ∩ C) = {3, 2} × {4} 

⇒ A× (B ∩ C) = { (3, 4),(2, 4)}
