उत्तर

 Given: 

\[f\left( x \right) = \frac{\sin 10x}{x}, x \neq 0\] is continuous at  \[x = 0\] .
\[\lim_{x \to 0} f\left( x \right) = f\left( 0 \right)\]
\[\Rightarrow \lim_{x \to 0} \frac{\sin 10x}{x} = f\left( 0 \right)\]

\[\Rightarrow \lim_{x \to 0} \frac{10 \sin 10x}{10x} = f\left( 0 \right)\]
\[ \Rightarrow 10 \lim_{x \to 0} \frac{\sin 10x}{10x} = f\left( 0 \right)\]
\[ \Rightarrow f\left( 0 \right) = 10\]
