1.Set Theory
easy
જો $A=\{3,5,7,9,11\}, B=\{7,9,11,13\}, C=\{11,13,15\}$ અને $D=\{15,17\} ;$ હોય, તો શોધો : $\left( {A \cup D} \right) \cap \left( {B \cup C} \right)$
A
$\{ 7,9,11,15\} $
B
$\{ 7,9,11,15\} $
C
$\{ 7,9,11,15\} $
D
$\{ 7,9,11,15\} $
Solution
$(A \cup D) \cap(B \cup C)=\{3,5,7,9,11,15,17\} \cap\{7,9,11,13,15\}$
$=\{7,9,11,15\}$
