XC

Answer

To convert the Roman numeral "XC" into a Hindu-Arabic numeral, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Roman Numerals**: The Roman numeral "XC" consists of two letters: X and C.

2. **Determine the Values of Each Letter**:
- The letter "X" represents the number 10.
- The letter "C" represents the number 100.

3. **Understand the Order of the Letters**: In Roman numerals, if a smaller numeral appears before a larger numeral, you subtract the smaller from the larger. Here, "X" (10) is before "C" (100).

4. **Perform the Calculation**: Since "X" is before "C", we subtract the value of "X" from "C":
- C (100) - X (10) = 100 - 10 = 90.

5. **Write the Final Answer**: Therefore, the Hindu-Arabic numeral for "XC" is 90.
