Question

Which of the following is the product of XII and L in numerical form.
A. 600
B. 310
C. 620
D. 2447

Answer 1

Hint: To find the product of XII and L in numerical form, we have to convert these Roman numerals into numerical form. The numerical form of XII is 12 and L is 50. Now, multiply 12 with 50 to get the required result.

Complete step by step answer:
We have to find the product of XII and L in numerical form. We can see that the numbers are given in Roman numerals. We will have to first convert it into numerical form to perform the multiplication operation.
We know that XII in numeral form is
XII = 12
We also know that L in numeral form is
L = 50
Now, let us multiply 12 with 50.
An easy way to do this is to multiply 15 with 5 and put a 0 at the end of their result.
\[\begin{align}
  & \begin{matrix}
   {} & 1 & 2 \\
\end{matrix} \\
 & \begin{matrix}
   \times & {} & 5 \\
\end{matrix} \\
 & \_\_\_\_\_\_\_\_ \\
 & \begin{matrix}
   {} & 6 & 0 \\
\end{matrix} \\
\end{align}\]
We obtained 60 on multiplying 12 and 5. Now, let’s put a 0 at the end of 60. We will get 600. Hence, the product of 12 and 50 is 600.
In other words, we can say that the product of XII and L is 600.

So, the correct answer is “Option A”.

Note: You should not convert the product into Roman numerals. You must know the numerical values of common Roman numerals to solve this question.
