मान लीजिए कि $U =\{1,2,3,4,5,6,7,8,9\}, A =\{1,2,3,4\}, B =\{2,4,6,8\}$ और $C =\{3,4,5,6\}$ तो निम्नलिखित ज्ञात कीजिए

$\left( A ^{\prime}\right)^{\prime}$

A

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

B

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

C

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

D

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

Solution

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

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

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

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