Question

If $A=\{1,3,5\},B=\{2,4,6\},C=\{1,4\}$ then which of the following is universal set?

• A. $\{0,1,2,3,4,5\}$
• B. $\{1,2,3,4,6\}$
• C. $\{1,2,3,4,5,6,7,8\}$
• D. $\varphi$

Answer 1

The correct option is C $\{1,2,3,4,5,6,7,8\}$

A set which contains all elements of set $A$, $B$ and $C$ is universal set
$\therefore 1,2,3,4,5,6$ should be there
So, option $\left(c\right)$ is correct
