Detailed Solution

It is given that we have to find the roman numeral representation of the greatest three-digit number.
We know that the largest

3

digit number is

999

.
Let's convert that into Roman numerals.

M = 1000

D = 500

C = 100

X = 10

V = 5

I = 1

Hence, we can write that,

900 = CM

90 = XC

9 = IX

Adding the numbers we get,

900 + 90 + 9 = 999

Therefore,

999 = CMXCIX

(1000 - 100) + (100 - 10) + (10 - 1)

.
Let's cross verify,

CMXCIX = (1000 - 100) + (100 - 10) + (10 - 1)

= 900 + 90 + 9

= 999

Correct option is 3.
