Question

If the replacement set is the set of Natural number (N) the solution set of $3x+4<16$ will be

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

Answer 1

The correct option is A

{1,2,3}

$\Rightarrow 3x<16-4$
$\Rightarrow 3x<12\Rightarrow x<4$
Since the replacement set = N (natural numbers)
Therefore, Solution set = {1,2,3}
