In the following state whether $\mathrm{A = B}$ or not :

$A = \{ x:x$ is a multiple of $10\} ;B = \{ 10,15,20,25,30 \ldots \ldots \} $

Option A

Option B

Option C

Option D

Solution

$A = \{ x:x$ is a multiple of $10\} $

$B=\{10,15,20,25,30 \ldots \ldots\}$

It can be seen that $15 \in B$ but $15 \notin A$

$\therefore A \neq B$
