निम्नलिखित समुच्चयों के सभी अवयवों ( सदस्यों) को सूचीबद्ध कीजिए

$B =\left\{x: x\right.$ एक पूर्णांक है, $\left.-\frac{1}{2}< x< \frac{9}{2}\right\}$

Option A
Option B
Option C
Option D

Solution

$B = \{ x:x$ is an integer, $ – \frac{1}{2} < n < \frac{9}{2}\} $

It can be seen that $-\frac{1}{2}=-0.5$ and $\frac{9}{2}=4.5$

$\therefore B=\{0,1,2,3,4\}$
