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)

Explanation:

A = {2, 3}, B = {2, 4}, C = {4, 5}

B ∩ C = {4}

∴ A × (B ∩ C) = {(2, 4) , (3, 4)}.
