Question

Write the Hindu-Arabic numbers of the following:

$\text{XIX}$

Answer 1

In the given question,

In Hindu- Arabic numbers,

We have,

$\text{X}=10$

$\text{IX}=\left(10-1\right)=9$

So,

$$\begin{gathered} \text{XIX}=\left[10+\left(10-1\right)\right] \\ =\left(10+9\right) \\ =19 \end{gathered}$$

Hence, the correct answer is $19$
