Question

Find out the truth sets of the following open sentences replacement sets are given against them.
$\frac{5}{x}>2;\{1,2,3,4,5,6\}$

• A. $\{2,3,4\}$
• B. $\{1,2\}$
• C. $\left\{5\right\}$
• D. none

Answer 1

Answer: (B)

$\{1,2\}$

$\frac{5}{x}=2$

$⟹x<\frac{5}{2}$

$⟹x<2.5$

Hence only $two$ values satisfies from set, i.e $\{1,2\}.$
