Question

The symbol that can never be repeated is
A.\[{\text{I}}\]
B.\[{\text{V}}\]
C.\[{\text{X}}\]
D.\[{\text{M}}\]

Answer 1

Hint: Here, we will find the correct option by repeating each symbol in the given question up to three times using the concept of Roman symbols.

Complete step-by-step answer:
We know that when the same symbol in a Roman Numeral is repeated, the value of the symbol is added to get the value of the numeral.
Since the symbols \[{\text{I}}\], \[{\text{X}}\] and \[{\text{M}}\] can be repeated only up to three times, but the value \[{\text{V}}\] is never repeated.
As when we repeat \[{\text{I}}\], it becomes 2 or 3 and there is no replacement, so the symbol \[{\text{I}}\] is repeated, if we repeat \[{\text{X}}\], it becomes 20 or 30 and there is no replacement, so the symbol \[{\text{X}}\] is repeated and if we repeat \[{\text{M}}\], it becomes 1000 or 3000 and there is not replacement, so the symbol \[{\text{M}}\] is repeated.

So, the only symbol that can never be repeated is \[{\text{V}}\].
Hence, the option B is correct.

Note: In this question, we have to use the concept of Roman numerals to understand the repetition of symbols. Also, we are supposed to write the values properly to avoid any miscalculation.
