Detailed Solution

Roman numerals are a number system that originated in ancient Rome. Numbers in this system are represented by combinations of letters of the Latin alphabet. For example, I stands for 1, V stands for 5, X stands for 10, L stands for 50, C stands for 100, D and M stand for 500 and 1000 respectively. The notation IV can be read as "one less than 5" and VI can be read as "one more than 5”. Each digit of the counting number is represented by a fixed symbol or combination of symbols.
Now let's get to the question. We are given the Roman numerals XC and we need to find the correct expression to represent them in the form of counting numbers.
Since C represents 100 and X represents 10, the notation XC can be read as "10 less than 100" because X is present before C, which is equal to 90, so XC represents 90.
Now 90 can be written as 100 - 10. So XC represents 100 - 10.
So option (1) is the correct answer.
