Question

If the replacement set is the set of whole number (W) the solution set of $4x-2<2x+10$ will be

• A. {1,2,3}
• B. {1,2,3,4}
• C. {0,1,2,3,4,5}
• D. {0,1,2,3,4,5,6}

Answer 1

The correct option is C {0,1,2,3,4,5}

$\Rightarrow 4x-2x<10+2$
$\Rightarrow 2x<12andx<6$
Since the replacement set = W (whole numbers)
Therefore, Solution set = {0,1,2,3,4,5}
