$U=\{1,2,3,4,5,6,7,8,9\}, A=\{1,2,3,4\}, B=\{2,4,6,8\}$ અને $C=\{3,4,5,6\}$ છે. નીચેના ગણ શોધો : $\left(A^{\prime}\right)^{\prime}$

A

$\{ 1,2,3,4\} $

B

$\{ 1,2,3,4\} $

C

$\{ 1,2,3,4\} $

D

$\{ 1,2,3,4\} $

Solution

$A=\{1,2,3,4\}$

$B=\{2,4,6,8\}$

$C=\{3,4,5,6\}$

$\left(A^{\prime}\right)^{\prime}=A=\{1,2,3,4\}$
