Question

Add the following and write the answer in Hindu-Arabic numerals.

$\text{XXX}+\text{XX =}$

Answer 1

We know that, In roman numerals $X=10$

Therefore,

$$\begin{gathered} \text{XXX}=\left(10+10+10\right)=30 \\ \text{XX}=\left(10+10\right)=20 \end{gathered}$$

So, $\text{XXX}+\text{XX =}\left(30+20\right)\text{= 50}$

Hence, $\text{XXX}+\text{XX}=\text{L}$
