Question

Max was told to number the pages of a book using Roman numerals. How would he number the ninetieth page?

• A. XL
• B. XC
• C. LXXXX
• D. XLXXXX

Answer 1

The correct option is B XC

We know that 100= C and 10=X.
$\therefore$90 = 100 - 10 = XC

We have used the following rule to write this:

If a Roman numeral with smaller value is to the left of the one with greater value, then we subtract the lower value from the higher value.
