Question
Solve: 12x < 50, when x ∈ N
Solution
\[\text{ We have }, 12x < 50\]
\[ \Rightarrow x < \frac{50}{12} \left[ \text{ Dividing both the sides by } 12 \right]\]
\[ \Rightarrow x < \frac{25}{6}\]
\[ x \in N\]
\[\text{ Then, the solution of the given inequation is } \left\{ 1, 2, 3, 4 \right\} .\]
