Question

Solve the inequation
$8-2x\ge x-5;x\in N$.

• A. $1,2,3,4$
• B. $4,5,6,7,........$
• C. $1,2,3$
• D. $5,6,7,........$

Answer 1

The correct option is A $1,2,3,4$

Given, $8-2x\ge x-5$
$\Rightarrow 8+5\ge x+2x$
$\Rightarrow 3x\le 13$
$\Rightarrow x\le 4.33$
Since it is given that $x$ is a natural no.
$\therefore x=\{1,2,3,4\}$
