Any letter cannot be repeated more than 3 times as we all know therefore; meaning of X is 10 XXX is 30 but we can't do it XXXX, because we know the rule of roman numerals one of the rule from it is "Rule Of Subtraction" so we will follow this rule. 50 means L 10 means X and in rule of Subtraction if there is any small number before any large number so we subtract the small one with the large one, so we will write XL because in XL X is smaller and L is larger so we'll subtract X from L answer will be 40 in Hindu Arabic numeral and in roman it will be XL.

Identifying the Missing Digit in the Equation
To find the missing digit in the equation X + XXX = ___, we need to determine the value of X.
Breaking down the Equation
- X represents a single-digit number.
- XXX represents a three-digit number where X is repeated three times.
Solving the Equation
Given X + XXX, we can substitute X with a digit that satisfies the equation:
X + XXX = 10X + X = 11X
To find the value of X that satisfies the equation, we can try different single-digit numbers until we find the correct one.
Identifying the Correct Answer
Looking at the options provided:
a) IV (which is equal to 4)
b) L (which is equal to 50)
c) XL (which is equal to 40)
d) M (which is equal to 1000)
Since X is a single-digit number, the correct answer should be a single-digit number as well. Therefore, the missing digit in the equation X + XXX = ___ is 4, making the answer option C - XL.
