Question

If $A\subseteq B\text{and}B\subset ̸A$ this means

• A. $A=B$
• B. $A\ne B$

Answer 1

The correct option is B $A\ne B$

Given two sets $A\&B$ such that $A\subseteq B\text{and}B\subset ̸A.$
From the first condition we can see:
$A$ is a subset of $B.$
This means $A$ can either be equal or not equal to $B.$
But since, $B\subset ̸A\Rightarrow A\ne B.$
Hence, from the two conditions, we can say $A\ne B.$
