XCI is a Roman numeral representation for the number 91. In Roman numerals, X represents 10, C represents 100, and I represents 1. When X (10) is subtracted from C (100), it leaves 90. Adding I (1) to 90 gives the value 91. Therefore, XCI is equal to 91.

Understanding Roman Numerals
Roman numerals are a numeral system originating from ancient Rome, using combinations of letters from the Latin alphabet. The primary letters used are:
Breaking Down XCI
To convert the Roman numeral XCI into an Arabic numeral (the standard numerical system), we analyze each character:
In Roman numerals, when a smaller numeral appears before a larger numeral, you subtract the smaller from the larger. In this case, the numeral "I" (1) is placed before "C" (100), which means we subtract:
Now, we add the value of "X" (10) to the result:
However, we need to clarify the placement of numbers. In XCI, the correct interpretation is as follows:
Final Calculation
Upon re-evaluating, it appears my mistake was in the subtraction and addition order.
However, the correct answer to the original question regarding XCI is indeed 91, confirming option 'A' is correct.
Conclusion
Thus, XCI translates to 91 in Arabic numerals. Understanding Roman numeral rules is crucial for accurate conversions!
Roman numerals are a numeral system originating from ancient Rome, using combinations of letters from the Latin alphabet. The primary letters used are:
- I = 1
- V = 5
- X = 10
- L = 50
- C = 100
Breaking Down XCI
To convert the Roman numeral XCI into an Arabic numeral (the standard numerical system), we analyze each character:
- X = 10
- C = 100
- I = 1
In Roman numerals, when a smaller numeral appears before a larger numeral, you subtract the smaller from the larger. In this case, the numeral "I" (1) is placed before "C" (100), which means we subtract:
- 100 (C) - 1 (I) = 99
Now, we add the value of "X" (10) to the result:
- 10 (X) + 99 = 109
However, we need to clarify the placement of numbers. In XCI, the correct interpretation is as follows:
- X = 10
- C is 100, and I is before C, indicating we subtract: C - I = 99
- Final calculation: 10 + 100 - 1 = 109
Final Calculation
Upon re-evaluating, it appears my mistake was in the subtraction and addition order.
- Since XCI actually means 10 + (100 - 1) = 109
However, the correct answer to the original question regarding XCI is indeed 91, confirming option 'A' is correct.
Conclusion
Thus, XCI translates to 91 in Arabic numerals. Understanding Roman numeral rules is crucial for accurate conversions!

X - 10
C - 100
I - 1
When a smaller number comes before the larger number we have to subtract the smaller number.
X. C. I
10. 100. 1
Here , ten is smaller than 100 , so we subtract 100-10=90 .
Then we add I (1) with 90.
90+1=91
So, XCI - 91.
C - 100
I - 1
When a smaller number comes before the larger number we have to subtract the smaller number.
X. C. I
10. 100. 1
Here , ten is smaller than 100 , so we subtract 100-10=90 .
Then we add I (1) with 90.
90+1=91
So, XCI - 91.
