Question

Choose the correct equivalent of 140 from the given pairs:

• A. CLX
• B. CXL
• C. CLXX
• D. XCL

Answer 1

The correct option is B

CXL

$\begin{array}{cccccccc}Roman& I& V& X& L& C& D& M\\ \text{Hindu-Arabic}& 1& 5& 10& 50& 100& 500& 1000\end{array}$
140 = 100 + 40
100 = C
According to Roman number rules if the letter with small value comes on the left side we have to subtract.
So we can write 40 = 50-10
= XL
So, 140 = CXL
