Question

If $X=3,5,7,9$ and $Y=2,4,6$, then

• A. $4\in X$
• B. {4} $\subset X$
• C. $Y\subseteq X$
• D. $4\in Y$

Answer 1

The correct option is D $4\in Y$

As per the question, 4 is an element of $Y$, not of $X$. Hence, $4\in Y$.

For the same reason, $4\notin X$ and $4⊊X$.

Also, $Y$ is not a subset of $X$, as the elements present in set $Y$, i.e., 2, 4, 6 are not elements of set $X$.
