Question

How will 23 be written in Roman numerals?

• A. XXIII
• B. XIII
• C. XIV
• D. XVIII

Answer 1

The correct option is A XXIII

$\begin{array}{cccccccc}\text{Roman}& \text{I}& \text{V}& \text{X}& \text{L}& \text{C}& \text{D}& \text{M}\\ \text{Hindu-Arabic}& 1& 5& 10& 50& 100& 500& 1000\end{array}$

XXIII = 10 + 10 + 1 + 1 + 1 = 23

XIII = 10 + 1 + 1 + 1 = 13

XIV = 10 + 5 - 1 = 14

XVIII = 10 + 5 + 3 = 18

Thus, XXIII = 23 is the correct answer.
