Question

The product obtained when $28$ is multiplied by $2$ in roman number.
A. LIV
B. LII
C. LVI
D. LVII

Answer 1

Hint: First we will calculate the number that we get when we multiplied $28$ with $2$. Now we will split the number into thousands, hundreds, tens and units. From this we will check each corresponding roman value for the digit in each place and finally we will place the roman values of each digit of the number at one place to get the final result.

Complete step-by-step answer:
Given numbers are $28$ and $2$.
Product of the given number is $28\times 2=56$.
Dividing the number $56$ with $10$ then we will get
$\begin{align}
  & 10)56(5 \\
 & \text{ }\underset{\scriptscriptstyle-}{5}\underset{\scriptscriptstyle-}{0} \\
 & \text{ }6 \\
\end{align}$
So, we can write $56$ as
$\begin{align}
  & 56=5\times 10+6 \\
 & \Rightarrow 56=50+6 \\
\end{align}$
Now the roman number that represents the number $50$ is L.
The roman number that represents the number $6$ is VI.
Now we can write $56$ in roman format by using the above values as LVI.
$\therefore $ The product of $28$ and $2$ is LVI.

So, the correct answer is “Option C”.

Note: We can directly write the roman numbers for $1$ to $100$ by using below chart

If you are unaware of the concept of the roman numbers, you can refer the following
A Roman number is the collection of the symbols (or letters/characters) C, D, I, L, M, V, X written in a sequential order. Generally, a subtractive notation is used in some cases to avoid four characters being replicated in sequences, such as IIII or XXXX, as shown below
If “I” is placed before V or X, it represents one less, then four is IV (one less than 5), and 9 is IX (one less than 10)
If “X” is placed before L or C, it represents ten less, then 40 is XL (10 less than 50), and 90 is XC (10 less than 100)
If “C” is placed before D or M, it represents a hundred less, then 400 is CD (100 less than 500), and 900 is CM (100 less than 1000)
