Write the following in Hindu-Arabic (Indian) numerals:

$\mathrm{XXXII}$

Convert Roman numerals to Hindu numerals using appropriate rules.

We know that $\mathrm{X}=10,\mathrm{I}=1$

$$\begin{gathered} \mathrm{XXXII}=\mathrm{XXX}+\mathrm{II} \\ =(10+10+10)+2 \end{gathered}$$

Therefore the required answer is $\mathrm{XXXII}=32$
