If A = {1, 2, 3}; B = {3, 4, 5}; C = {4, 6}, then $\text{A}\times(\text{B}\cap\text{C})=?$
  • A
    {(2, 4)(1, 4)}
  • B
    {(2, 4)(3, 4)(5, 6)}
  • C
    {(1, 4)(2, 4)(3, 4)}
  • D
    None of these

Answer

  1. {(1, 4)(2, 4)(3, 4)}

Solution:

Given,

A = {1, 2, 3}

B = {3, 4, 5}

C = {4, 6}

Now, $\text{B}\cap\text{C}=\{{4\}}$

$\therefore\text{A}\times(\text{B}\cap\text{C})=\{(1,4),(2,4),(3,4)\}$
