Question

In Roman Numerals, a number has been written as MMXVIII. In Arabic numbers it will be ............(Note:- DO NOT include spaces in your answer)

Answer 1

Correct Answer: 2018

The Roman numeral MMXVIII represents a number in the Arabic numeral system. To convert it, we need to understand the value of each Roman numeral and sum them accordingly:

• M = 1000
• X = 10
• V = 5
• I = 1

The numeral is broken down as follows:

• MM = 1000 + 1000 = 2000
• X = 10
• V = 5
• III = 1 + 1 + 1 = 3

Adding these values gives the total:

2000 + 10 + 5 + 3 = 2018

The calculated Arabic numeral 2018 aligns with the given range (2018,2018), confirming the conversion is correct.

Answer 2

We can also check this by building the Roman numeral back up from the number 2018 and seeing if it matches the given numeral MMXVIII.

1. Step 1: The thousands digit is 2, and 2000 in Roman numerals is written as MM.
2. Step 2: The tens digit is 1, written as X.
3. Step 3: The units digit is 8, written as VIII (5 + 3).
4. Step 4: Putting these together from largest to smallest gives MM + X + VIII = MMXVIII, which matches the numeral given in the question exactly.

Since building up from 2018 reproduces MMXVIII exactly, the numeral does represent 2018.

Therefore, the correct answer is 2018.
