Question

Solve the inequality $24x<100$ if $x$ is a natural number.

Answer 1

$24x<100$

$\Rightarrow x<\frac{100}{24}=4\frac{1}{6}$

Thus the natural number satisfying the inequality is $x=4$

Any other natural number less than $4$ also satisfies the inequality.

So the solution is the set $\{1,2,3,4\}$.
