If $A=\{3,5,7,9,11\},B=\{7,9,11,13\},C=\{11,13,15\}$ and $D=\{15,17\}$.Find (v) $B\cap D$

$\begin{array}{1 1}(A)\;\phi&(B)\;\{7,9,11,13\}\\(C)\;\{11,13,15\}&(D)\;\{7,9,11,13,15\}\end{array} $

1 Answer

$B=\{7,9,11,13\}$
$D=\{15,17\}$
$\therefore$ There is no common element in B & D
$\therefore B \cap D=\{7,9,11,13\}\cap \{15,17\}$
$\Rightarrow \phi$
Hence (A) is the correct answer.
